Graphics Slow After Upgrade 14.04 - 14.10

Status changed to 'Confirmed' because the bug affects multiple users.

Affects me too.

Using Xubuntu. Graphics very slow on something as simple as the moving balls on the google search page.

I'm admittedly using an old machine (Dell Latitude D400) but some simple graphics operations are far far slower on 14.10 than with 14.04 or 12.04

its crazy youtube and similar videos became enjoyless.
Video is slow and dashed

Affects me too.

Google Chrome, Image Viewer, GVim, Gnome Terminal are all very slow.
Switching workspace to the above applications are very slow as well.

However, playing Team Fortress 2 on Steam works perfectly.

I am using System76 15.6" Gazelle Professional laptop with Intel High Definition Graphics 4600. Ubuntu Gnome 14.10 upgraded from 14.04

Affects me too. I see identical behavior.

My system is a relatively newer Dell Optiplex 7010 with Integrated Intel graphics.

00:02.0 VGA compatible controller: Intel Corporation Xeon E3-1200 v2/3rd Gen Core processor Graphics Controller (rev 09)

So far, it looks like everyone reporting the problem has Intel graphics.

This bug affects me too. I have a Dell inspiron 1525 with intel graphics. I tried a fresh install but the problem persists.

If the graphics driver is the problem, would it be possible/sensible to downgrade it to whatever version we had und 14.04? Does anyone know how to do this?

After a 14.10 install from scratch (no update) with Gnome Shell on Intel 915 graphics (Lenovo S440), I still have the same issue. Most noticeable is the very slow text editing in gedit.
There is no issue when I use Unity, Gnome Classic or Xfce.

My understanding is that the problem doesn't necessarily lie in Intel graphics driver, if that would be the case, sluggish performance would affect desktop as a whole, regardless of applications currently running. At the moment, my 14.10 Gnome desktop is perfectly smooth until I launch certain applications like Google Chrome or Image Viewer. Gedit also caused this issue until I upgraded it to 3.12.2 from gnome3-team's ppa - now runs without a hitch. That makes me think that these applications are rendered using different library/method which is not accelerated by graphics driver - that's how in laymans words I would describe my understanding of the case.

I have also reported #1385764 which has been marked as duplicated of this bug, where I explained the issue further.

I can confirm the observations made by Dawid Lorenz

I tried replicating the actions in the video he posted in his own bug report, and found the results to be the same.

- Opening the image viewer made desktop switching noticably slower.
- Launching Google Chrome brings about very noticable performance changes overall
- Upgrading my Gedit from 3.10 to 3.12 eliminated the issue with slow performance in the text editor

Definitely seems that at least part of issue bight be in drawing/updating of gnome 3.10 applications

However, I've noticed:

- Opening a gnome terminal window (NB: Version 3.12) also brings about the sluggish performance in desktop switching

So I'm not sure the issue can be solely attributed to the the 3.10 vs. 3.12 changes.

Additionally, Rhythmbox 3.0.3 is itself and makes everything else, ie. the user interface painfully slow.

Only does this when the program visible, there is no problem when it's playing in the background (Alt-F4)

Similar issue for my NVIDIA GeForce 610M Optimus hybrid graphics laptop. Xorg is working harder and taking more CPU % than in 14.04. Occasionally, the graphics hang with the HDD running. In 14.04 it also occurred but it tended to come back after 30 seconds or so. 14.10 takes longer and a couple times it hung completely and I had to crash the system using the power button.

I'm having the same issue - but only since upgrading from 14.04 to 14.10. I've been a long time gnome3-team ppa and gnome3 user.

The *big* difference I'm seeing is that it's not consistent. Maybe 1 out of 10 boots the UI is so sluggish it's unusable.

Otherwise my issues match everyone else's: once I open Chrome or switch virtual desktops, the UI starts crawling. Some games work fine, others play at less than 1 fps.

I'm on a sys76 w/ Intel Corporation Crystal Well Integrated Graphics Controller (rev 08) for graphics.

Sorry for the double-post. Launchpad was giving me 500s and timeouts. Please delete this and one of the duplicate comments.

Ubuntu Gnome 14.04 to 14.10. Slow switching between workspaces when certain apps are running. So far seems when Firefox and Evolution are running, switching between workspaces is very slow. Quit these apps and things speed up. Don't experience same issue if I run Epiphany instead of Firefox. So certain apps seem to be slow for workspace switching for me. TJ

My Wine based games are so much choppy after upgrading from 14.04 to 14.10.

I'm just running standard Ubuntu with Unity, upgraded from 14.04 to 14.10. Video playback is choppy from youtube, netflix, etc. I am experiencing some of the same problems as #17, switching between workspaces is slow on occasion. The worst problem is that the Dash is quite slow, it takes about 3 seconds to pop up after I press Super, when it used to be more or less instantaneous. And typing in the Dash search box takes about 1 second per letter.

My hardware is a desktop with Intel integrated graphics. It's not new (an i3 chip from several years ago) but I never had a problem with 14.04.

OK, an oddity for me today I thought I would post.

I also had very slow UI since updating from Ubuntu Gnome 14.04 to 14.10. Workspace or window switching was slow as molasses. Seemed the two apps for me that made window switching real slow were Evolution and Firefox. Once I quit those things seemed normal.

I have been running my i7 based system from the Intel 4000 based on board graphics as I could not get my nVidia 750ti to work. Therefore I had BIOS set to use the on-board video.

Today I decided to set video back to PCI1 that my nVidia is connected to but leave the HDMI display connected to my on-board video. Took longer to boot but she did boot and guess what..... my system is running much faster UI now. Those problem apps from before that bogged down the workspace switching.... not doing it any more.

Really strange but for me.... the UI is peppy again.

I will run like this for a day or two to see what happens.

Just updated from 14.04 and I have the issue. Tried the proprietary nvidia driver and the free one. I see no difference. I have Intel + Nvidia in an Asus laptop.

Affects me too.

Fresh install of Ubuntu 14.10 on brand new desktop computer with Intel integrated graphics. Launching directly gedit as only graphical application after boot, display freezes for a noticeable period of time (10-20 seconds) when editing with a mix of keyboard entry, keyboard shortcuts and mouse edition.

I see this too on my Thinkpad T410 (14.10 upgraded from 14.04). Chrome is particularly bad but, strangely, it's much worse when maximized. When not maximized, refresh is still slow but not as unbearable.

As suggested here: http://ubuntuforums.org/showthread.php?t=2249774, a workaround is to upgrade to gnome staging. The forum post suggests testing, but staging solved all problems for me:

sudo apt-add-repository ppa:gnome3-team/gnome3
sudo apt-add-repository ppa:gnome3-team/gnome3-staging
sudo apt-get update
sudo apt-get dist-upgrade

This can of course introduce other problems.

Can confirm that upgrading to 3.14 according to the instructions written here has seemingly fixed the issue for me:

http://www.webupd8.org/2014/10/how-to-install-gnome-314-in-ubuntu.html

Everything seems very responsive right now, vlc, rhythmbox, chrome, firefox, gedit and terminal.

Cannot say however what other consequences this may have had..

I have the same problem with two different notebooks with intel graphics after upgrade to 14.10. (Acer - Intel Core i3 380M - HD Graphics, Asus - Intel Core i3 3217U - HD Graphics 4000).
I use Ubuntu with Unity.

Affects me too.

I have Unity and 14.10 upgraded from 14.04, Dell E7240 notebook with Core i7-4600U and integrated Intel Haswell-ULT video.
First the problem seemed to appear after upgrade when I decided to try unity8 and installed it packages (the graphics remained slow even when I was in classic Unity session), and everything disappeared, when I removed unity8.
Now the problem reappeared, and I found unity8 installed again. So I removed it with all the stuff depended on it and the is likely went away again.
WARNING: if anyone would try my method, it removes indicator-network. I myself prefer nm-applet, it requires network-manager-gnome to be installed.

Guys, I fixed the issue by installing xserver-xorg-video-intel package.
It have been deleted during updating and system used the vmware driver, which is pretty slow

I'm seeing xserver-xorg-video-intel already installed. It needed an update which I did. Currently, running kernel 3.16.0-24-generic and have been experiencing consistently many system hangs. Can move the mouse pointer, even flash videos continue playing because can hear the sound but the entire display is frozen. Seems to happen when the display is being stressed usually with a second monitor and under load. Couple days ago booted with 3.13.0-34-generic and the same thing happened. With 14.04, typically when freezes occurred if I waited a minute or 2 the system would recover and I didn't need to force a hard reboot. Using NVIDIA GeForce 610M Optimus hybrid graphics laptop and Bumblebee 3.2.1-5. Considering going back to 14.04.

The problem described by Matthew Tucker-Simmons, affect me too on an acer 5742 g notebook with intel/nVidia drivers (Optimus).

The bash is very slow and it take more than a second to type a letter in the search box.

Moreover: when I use Gnome Shell and stast gnome monitor, a CPU core is always at 49%-50%

Considering going back to 14.04 where everything was OK

I was experiencing something very similar to this and stumbled across https://bugs.launchpad.net/ubuntu/+source/gedit/+bug/1376494 which suggested installing ibus-gtk.

1. sudo apt-get install ibus-gtk
2. reboot

Now my gedit seems to work fine.

HTH

This affects me too on Ubuntu Gnome 14.10 with Lenovo Yoga 13 and Intel HD 4000. Basic gnome animations are slow, or better said, they always get at least one lag during animation. I have to say that I played with unity and unity8, then uninstalled it.
ibus-gtk was installed so this was no fix for me. I am going to try Gnome Shell staging as suggested. Wanted to try it before anyway...

useful info for owners intel cards with i915 driver - i managed to resolve the issue with video lags by driver (installing xserver-xorg-video-intel) from https://launchpad.net/~xorg-edgers/+archive/ubuntu/ppa/+packages?field.name_filter=intel&field.status_filter=published&field.series_filter=
now all works smoothly and fast, similarly to 14.04

Just to add: http://askubuntu.com/questions/540964/upgraded-to-ubuntu-14-10-and-everything-lags?noredirect=1#comment743103_540964 and the link to another Askubuntu question of this sort.
Very annoying this topic. I can't really work anymore (Lenovo X1 Carbon; upgraded from 14.04 to 14.10)

Same thing on the HP's Chromebook 14 on Intel, on the latest kernels (3.17-3.18). It happens after couple of hours of work or moments with high CPU load. Bug brings slow redrawing in Opera (presto) and Chromium, but Firefox refreshing stays smooth. Also, appears a high CPU consumption by XOrg, when browsers are opened.

After installing gnome-staging, gnome stopped to lag. However, my wine games are very slow. Not sure if this is related to same problem, or other problem from upgrade.

same thing to me, vaio, nvidia geforce
but not directly after upgrading !
after upgrade it seems good... however i forgot my laptop not unplugged, battery is down. When i restart it, i found everything is tooo slow makes me little bit crazy :/
what to do?

Occurs with me also.
Asus X553 MA Notebook.
Intel HD Graphics 4000, Baytrail 3530 processor.
Browser/Image viewer etc behaving too much slow and unusable.

After upgrading to 14.10 tonight, I noticed a slowdown especially while using totem. I was getting about 0.2 frames per second using totem. VLC appeared to run but was choppy at larger resolutions.

Other than totem, the primary symptom was sluggishness. It took 1 second for gnome-shell to react to selecting and dragging a gnome-terminal that was in the background behind chrome.

After the upgrade, the kernel appeared to be running the i915 module (as seen by lshw -c video). ibus-gtk was already installed, so it wasn't that either.

Then I installed the edger's xserver ppa. This helped both gnome-shell and totem, considerably.

Videos actually ran for a second or two at a time, but were still choppy in totem. What appeared to be happening was that gnome-shell would spike the cpu going to 80% when totem was running. Gnome-shell was more responsive but still sluggish using the edgers xserver. Dragging a gnome-terminal in the background still took around a second for gnome to respond.

Then I installed gnome-staging ppa. This helped the most, eliminating the gnome-shell cpu spike while playing totem, and making the windows much more responsive including dragging a gnome-terminal that was in the background.

So it looked like both things helped to varying degrees. I got a better totem frame rate using the edgers x server. But gnome-staging gave me a better gnome-shell performance.

The bug (or at least something that seems like the bug) also appears when running xmonad and unity-settings-daemon.

Are there any known workarounds?

Installing xorg-edgers improves general graphics performance, but there is still some tearing when playing games.

I'm attaching a Xorg.0.log that has an interesting-looking backtrace related to the event queue near the end. Maybe this will help with the issue.

This bug also affects me, just updated from 14.04 to 14.10 this morning after getting in to work on my Dell XPS M1530, and development has become impossible. Eclipse Juno has become almost totally non-responsive.

I've experienced a significant (subjective) performance boost by blacklisting intel_powerclamp and intel_ralp .

Can confirm, poor performance on all video players , browsers. and Unity Dash.

Re: my earlier post about blacklisting certain modules, it might be the case that I had actually worked around a version of bug #1389077 , since the main symptoms after upgrading to xorg-edgers were random I/O freezes (mouse, keyboard, audio, or graphics cutting out for a secord or so). I think more testing is required.

I've been using the xorg-edgers packages without any fault I've noticed,
and the blacklisting has removed the performance throttling which took
place. The only problems I have are graphics acceleration in Firefox and
Chrome, as far as I'm aware.

Just tried once again with Ubuntu 14.10 live-CD on a usb stick and Gnome was fast as always.

During upgrading, updates were downloading alongside the image, perhaps an
undocumented bug lies in one of those? Or is it the usual discrepancy
between the live-CD and an installation?

I did a fresh install on an empty system without downloads (no internet connection) and without restricted-extras.

Live-CD Gnome was fast as usual, rebooting into the installed system left me with a slow desktop.

Does/did anyone else have problems with OpenGL-intensive things (for example Dota 2) periodically freezing (to the point of temporalily losing custom mouse cursor)?

Gameplay just seems slowed down, both by fps, and the game clock, perhaps
that's just poor coding though. Are you playing it with Desktop Compositing
disabled, and is it only rendered on the CPU? Those will very negatively
affect performance.

Is someone working on it or should we expect the patch in the next release itself? This is really afftecting a lot of users.

Fast performance on my Samsung Series 9:

I've got same card as your Samsung and got sluggish performance, so this seems irrelevant.

I am having this problem on a fresh Ubuntu GNOME 14.10 install. Windows jerk when I drag them, and there's a lot of redraws. This is a Thinkpad T430s with Intel graphics.

Re: #53, I'm running xmonad (with unity-settings-daemon in the background) so I don't think composting is an issue. Also, these performance issues began with the upgrade (and seem to apply to any non-trivial fullscreen OpenGL application), so I assume this is the bug.

For reference, I'm running:
00:02.0 VGA compatible controller [0300]: Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller [8086:0116] (rev 09) (prog-if 00 [VGA controller])

Re #34: Installing updates from xorg-edgers didn't help here.

I'm attaching my dmesg output. There's some i915 messages that seem relevant.

Same problem here after upgrading from 14.04 to 14.10 in a Dell Latitude E6410.

I've installed the gnome2-staging PPA (as per #24) and the xorg-edgers PPA (as per #34) but the problem remains, I'm sad to say.

This bug might be related to this:
https://bugs.launchpad.net/ubuntu-gnome/+bug/1385764

Most of my issues with graphics-intensive applications appear to have been resolved by upgrading to kernel 3.18.4 (with inel_powerclamp blacklisted and xorg-edgers), at least with the performance . OTOH. I'm experiencing some keyboard input lag in Firefox with this configuration at random intervals.

The input lag seems to have resolved itself somewhat. Weird.

Blacklisting intel_rapl and intel_powerclamp didn't help here :/.

Celian: get rid of the 3rd party drivers and things should work

for the rest; this is not a me-too meta bug, file a new one if you don't have 01.org drivers installed

Timo, I think you misunderstood Celian's description. He isn't using 3rd party drivers. He's using Ubuntu 14.10 native drivers just as almost everybody else in here. He just pointed out that some foruns advised to use Intel's drivers but those are older than the driver in Ubuntu 14.10.

I may be wrong, but please, read the description again to check it.

Thanks.

I don't understand how this bug can be 'invalid', when it perfectly describes the symptoms on my fresh Ubuntu 14.10 installation.
It's discouraging to see that all commenters' effort to help identifing the cause of the problem is dismissed with 'this is not a me-too bug'.

@Timo Can you reopen #1385764 please, it cannot be a duplicate of an 'invalid' bug.

@Timo, @gnustavo is correct.

I am not using any 3d party drivers and simply referred to a proposed solution that I haven't used.

Invalid ??? Most of the people reports here have native drivers.

This bug is not invalid, the only invalid thing is the experiance with 14.10 in last 4 moths, for so many people with intel GPUs.

Updating to the latest xorg drivers using the xorg-edgers PPA seemed to have solved the slowness for me, but at the expense of stability -- from time to time I get complete system lockups.

Status changed to 'Confirmed' because the bug affects multiple users.

I have just gave a shot with gnome3-team's staging PPA. Upgraded, rebooted and my desktop seems perfectly smooth as butter again. I have actually forgot already how the desktop is *supposed* to work - it's THAT good compared to Ubuntu Gnome 14.10 + gnome3-team stable PPA installation.

So far didn't notice any other side effects apart from mouse cursor issue which I've already solved.

Same as #74: Running with Gnome 3.14 from gnome3-team PPA, everything smooth now.

Here's the screencast demonstrating how the desktop performed BEFORE gnome3-team staging PPA upgrade:

https://www.youtube.com/watch?v=0LhKhdgKHiQ

and AFTER such upgrade:

https://www.youtube.com/watch?v=7pMasD4SfdQ

I run Ubuntu Gnome 14.10 with Gnome 3.14 installed from gnome3-team's staging PPA as suggested above. I also installed updates from xorg-edgers. Even after this, graphics are still more sluggish than they were on 14.04:

- HD video playback is slow and shows artefacts,
- background transparency is gone (when showing the "Enter a command" dialog for example).

I tried to upgrade the intel drivers by strictly following the instructions on this comment on Webupd8 : http://www.webupd8.org/2014/10/how-to-install-gnome-314-in-ubuntu.html#comment-1672573003.

After doing this, things seems to work better. First indicator is background transparency is back (but not on the terminal, it is another story here ;-)). HD video playback is also smooth now.

Just a quick note to my previous comments #74 and #76 - I did NOT install any updates from xorg-edgers or anything like that. The only thing I did was dist-upgrade to gnome3-team's staging PPA as per step-by-step instructions in this article: http://www.webupd8.org/2014/10/how-to-install-gnome-314-in-ubuntu.html

Has anyone tried 'fixing' the slow graphics on Ubuntu 14.10 on Intel graphics hardware by upgrading to an pre-release version of Ubuntu 15.04? I might be tempted to swap from 14.10 to 15.04 Beta1 (released Feb 26th) if it fixes the sluggish graphics performance.

Also affects Xubuntu 14.10 on an X201 tablet. Chromium runs very slowly unless the --disable-gpu is used.

Experienced this issue on a Dell XPS 15(9530)
intel HD4400 chipset with optimus and an nvidia GT750M card

lsmod shows that after enabling the additional drivers for nvidia, both intel and nvidia modules are loaded. Below is some selected lines from lsmod output:

i2c_algo_bit 13406 1 i915
drm_kms_helper 61627 1 i915
drm 310919 6 i915,drm_kms_helper,nvidia
video 20128 1 i915

According to one askubuntu entry (http://askubuntu.com/questions/128433/how-to-prevent-nvidia-kernel-module-from-loading-ubuntu-12-04-64-bit) bumblebee acts by blacklisting the nvidia module and only having it load for certain display contexts (the windows you want to be accelerated). Seemingly this was in 2012, but i think it probably holds true today

So by simply installing the available bumblebee package (in my case i ticked enable nvidia proprietary driver support in the software center) and rebooting, all performance issues were solved.

Thanks for your report, but this bug has nothing to do with nvidia graphics cards.

This bug is still present on Ubuntu Gnome 15.04 beta on intel card

@grigio: What's the output of "gnome-shell --version"?

I'm running 'vanilla' Ubuntu 14.10 (without any PPAs) on an HP Probook 6450b (with intel graphics). My graphics were running very slowly up until yesterday when I updated (I presume it was the update to linux-image-3.16.0-31.41). The HUD runs smoothly, as does video. Has anyone else noticed a speed up?

Actually, it appears that graphics are slow again today.

Sadly, it's slow for me as well.

I completely removed my 12.04 LTS, re-organized partitions, then freshly installed 14.10, now Chromium and Gedit are running unbearably slow. I have Dell Latitude E6510 with 560 M processor and integrated Intel GMA HD graphics card. I sure did not have this issue with 12.04.

I remember version 10.04 did not support the 1080p resolution on Intel integrated gfx, it took awhile for a fix to come out.

Not sure what to say or think about this either, Ubuntu is trying to be "the desktop distro" but with such bug...!? There are lots of laptops out there with Intel integrated graphics.

This is not only in Ubuntu GNOME, Chromium runs equally slow in Unity and fallback mode.

I agree with vincegata.

This bug makes the current version of Ubuntu unusable on a large percentage of the hardware out there. Yet, it sits with an importance of "undecided" and "unassigned". What does it take to be rated a high importance and get someone looking at this?

This is really unacceptable for a distribution that is trying to make a presence in the desktop space.

Lenovo G460
Running 14.10
Intel Ironlake Mobile graphics

No issues with previous distributions, but for some reason in 14.10, Chrome browser lags. Huge lag. From videos, scrolling up/down on a wiki page, to app. animation (creating a new tab, hitting the plus sign, the new tab bar lags during draw())

However, oddly enough, I play 720p, 1080p movies with ease (no lag, no chopping, all good). Something doesnt add up.

Sounds like a Chrome problem? I dont know, but I doubt its Chrome at this point. (Chrome version: 41.0.2272.76 (64-bit))

anyone with a similar pc? similar video card? with a solution?

Hi,
I have a DELL E6510 and since the upgrade to 14.10, Chrome is also very slow and Atom (based on Chronium). I can't use it.

Processor: Intel® Core™ i5 CPU M 560 @ 2.67GHz × 4
Graphics card : Intel® Ironlake Mobile

Hi, I've a HP Elitebook 8440p running Ubuntu 14.10 fresh installation. Chrome is very slow (I switched off hardware acceleration, otherwise I can't use it), Unity dash is slow, Netbeans is slow. General Window resize is slow. Can not play videos. To fix this issue I installed: "xorg-edgers fresh X crack" - no success; I tried: ppa:gnome3-team/gnome3(-staging) - did not help; intel acceleration mode: sna, uxa, glamor, no success, I tried fresh Kernel 3.19 nothing, updated my BIOS, no change. My system stays slow. I'm using Ubuntu since years and it's the first time I stuck in an issue - anyway - please let me know if you need further information - I'd like to help to get this issue solved! Thanks, Philipp

ditto for the most part (ppa:gnome3-team/gnome3(-staging), updated video

ditto for the most part (ppa:gnome3-team/gnome3(-staging), different video drivers, reinstalled 14.10)

Let me know if you need info as well. I want my Ubuntu back the way it was (blazing-fast).

My system speed got much better after disabling bootloader graphics, VESA framebuffer driver and PAT memory in xdiagnose. As a result Chrome is running fine hardware accelerated, unity dash is back on normal speed, my system plays videos in full hd. Also my general system load is much lower now. Maybe this solution works for you as well.

Thanks philipp_023, it is better for me.

Thanks philipp_023, that appears to fix the problem for me too!

Yep philipp_023 suggested solution that worked for me as well after reboot. ATI Radeon HD card here.

ditto.
philipp_023 suggestion worked for me as well.
chrome is blazing fast once again and videos are not lagging/choppy in the browser. back to normal.

Same problem here, specifically with Chrome/Chromium. As others reported, there is visible flickering when scrolling or loading a page. Other programs work fine (e.g. Firefox). Tried philipp_023's solution; no luck.

philipp_023's fix didn't work for me either, running on i915. Chrome and
video playback are still very slow and flickering occurs while playing HD
video back.

Initially I wrote that philipp_023 helped, but it helped only for one boot, then it was slow again for some reason regardless of bootloader graphics, VESA framebuffer driver and PAT memory checkobxes in xdiagnose.. Problem still here, very annoying!!!

when is the next build due for release?

After upgrading from 14.10 to 15.04, there seems to be better performance. Things aren't as slow and choppy as before. It's possible that this issue has been fixed in Vivid Vervet (15.04) and those who are suffering from this and are able to test and confirm, please share your findings here.

Thanks.

I've updated to 15.04 this morning, and the performance after installing
the normal updates was still poor. I didn't attempt using the staging
updates, or the latest xserver-xorg-video-intel update, and instead
downgraded to 14.04.2 in the meanwhile.

Thanks a lot philipp_023 !! works likea charm !!

Mauro:

in a terminal, run: "sudo xdiagnose"
this will come up (see image):
http://screenshots.ubuntu.com/screenshots/x/xdiagnose/9907_large.png
uncheck everything in "workaround", click apply. done.

restart your computer and you should see a performance gain.

I think you meant to check those boxes, since that's what philipp_023 said
in his fix:
"My system speed got much better after disabling bootloader graphics, VESA
framebuffer driver and PAT memory in xdiagnose."
If you've unchecked everything, then the fix is not the cause of increases
in performance.

I can confirm that the workaround provided by philipp_023 works for me. Graphics and system performance are very good now.

Previously, I had downloaded the latest Intel Drivers (https://01.org/linuxgraphics/downloads) and only saw a small speed increase.

00:02.0 VGA compatible controller [0300]: Intel Corporation Core Processor Integrated Graphics Controller [8086:0046] (rev 02) (prog-if 00 [VGA controller])

I found a similar bug #1314587 but for unity, perhaps X.org is the culprit here. I still get this occasionally, although I'm using the fglrx driver.

I tried disabling PAT memory in xdiagnose only, rebooted and then got the exact same performance as the original reporter. After reverting the change everything was ok, but as I mentioned before, I still get poor performance from time to time.

Same here (Toshiba Z930 i5) with proprietary Intel driver (1.0.8) on HD 4000 but in other computer (Toshiba Z930 i7) with HD 4400 works perfect.

philipp_023 solution doesn't work. Any solution worked.

I think that is a very important bug and can't be without solve during 6 months.

Lito: Did you find a solution that worked for you? Or did nothing work,
even after installing the latest builds from xorg-edgers and gnome3-staging?

#115 Logan, any change has worked:

1) Try: Disabled bootloader graphics, VESA and PAT memory with xdiagnose and reboot. Result: no changes.

2) Try: Installed gnome3 and edgers packages and reboot. Result: no changes.

add-apt-repository ppa:xorg-edgers/ppa
add-apt-repository ppa:gnome3-team/gnome3
add-apt-repository ppa:gnome3-team/gnome3-staging

apt-get update && apt-get dist-upgrade

3) Try: Enabled bootloader graphics, VESA and PAT memory with xdiagnose and reboot. Result: no changes.

One comment about this problem is that this bug only affect me when the external monitor is connected. I have two monitors connected on laptop, one using HDMI and other with VGA.

I can replicate the exact same issue that Celian demonstrates in his YouTube videos. In my instances, my Laptop (Lenovo T400) acts exactly the same way, however I have found the following:

If I set modeset for my i915 video driver to 1 (or 0, which pulls the setting of DRM_I915_KMS=y from the kernel config), my framerate increases from 60fps to ~1000fps. This also fixes the sluggishness Celian and others have been complaining about, at least in my instance.

Adding "options i915 modeset=0" to /etc/modprobe.d/i915-kms.conf may be of benefit to some users of the i915 module on this bug report.

Matthew's fix only broke my display aspect ratio, forcing me to remove the
added file from a login console to restore normal functioning. Has anyone
else had any luck with it?

I have this bug too. Never in 14.04, but in 14.10 and 15.04 in all DEs. I found a way on youtube that at least solves it for me. It's probably a workaround more than a solution but it works for me.

sudo apt-get install mesa-utils

Now to solve the video tearing

sudo mkdir /etc/X11/xorg.conf.d/

echo -e 'Section "Device"\n Identifier "Intel Graphics"\n Driver "Intel"\n Option "AccelMethod" "sna"\n Option "TearFree" "true"\nEndSection' | sudo tee /etc/X11/xorg.conf.d/20-intel.conf

sudo reboot

Ever since that everything's smooth as a baby's butt

Thanks Sancho! This trick also works like a charm for me!

Thanks!

Thanks, Sancho (steven-sanchez) on #120

Hi there. I had the same problem (especially noticeable in Chrome) on Ubuntu 16.04 (latest updates) with Gnome Shell installed and using the Dell XPS 13 9350 (latest firmware updates installed) with two displays (4k & 1080p) connected via Displaylink Docking Station D3000.

The fix of philipp_023 fixed it! Thank you very much for sharing!
Using the notebooks UI felt laggy like hell but now things run incredibly smooth again :) There are still minor bugs or lags when I interact with the Gnome UI or change display settings but this comes very certainly from the DisplayLink driver I had to install.

Cheers!

Update: okay, the only thing which is still annoyingly slow is the terminal output (if the system has to update/rerender the terminal because of new stdout/err text it's updated with ~1FPS :-/ The rest runs smooth ...

Sorry - there is no edit button for my previous posts ...

When I run (as mentioned by philipp_023):
> sudo xdiagnose

CHECK only these two: "diable bootloader gfx" & "diable VESA"

but UNCHECK: "disable PAT memory"

Everything (both Chrome/Gnome-Shell UI and Terminal UI) works like a charm for my setup.
Maybe this helps anyone.

Cheers

thanks to philipp_023, my T410 is alive and smooth again after a bad period when I cant use anymore virtualbox because too slow...

It is really annoying when something like this happens. We have to search what is causing the problem, google it, find the right bug and may be a solution or workaround.

Is there an app that check for bugs on a certain computer model and distrib, and alert users that hown this computer about existing bug?
