On-screen text disappears after suspend

Things I've tried that do not work:
* initctl restart unity-panel-service restarts the panel, but the text is still missing
* suspend and resume does not fix the issue
Also, I have one example screenshot. However, the issue also affects the file selection dialog in Chromium, so I can't upload it now.

This also affects the menus in Document Viewer, as well as the entire screen of a terminal window. Unity button & scopes are unaffected. Also, all six of the tty terminals appear to be blank.

The bug occurred again following a resume. Additional information about the applications affected has been added to the description.

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

Workaround:

Set the COGL_ATLAS_DEFAULT_BLIT_MODE env var to a value other than "texture-render", which is the default.

Appears to be this bug: https://bugs.freedesktop.org/show_bug.cgi?id=88584

See comment 17 for technical details; the details he lists are consistent with what I played around with.. disabling 2D acceleration eliminates the bug but obviously that is not desirable.

I tried setting COGL_ATLAS_DEFAULT_BLIT_MODE to framebuffer and performance seems to become poorer and I start having glitches when changing workspaces (in Awesome window manager). Not sure if that's a satisfactory workaround.

Interestingly there are reports for similar issues dating back to 14.04 but I never had this problem until now with 16.04.

Update: my current workaround is now to remove xserver-xorg-video-intel,
and instead use the built in modesetting driver. So far, I've had no
issues, and acceleration works fine.

Ah, interesting, I'll try that. Apparently Debian recommends using the modesetting driver too. https://packages.debian.org/sid/x11/xserver-xorg-video-intel

I'm having a similar issue. I found that switching to a virtual terminal and back again fixes the missing text in my case (Ctrl+Alt+F1 then Ctrl+Alt+F7).

Same problem here on a Dell XPS 13. The following three proposed solutions did _not_ work:

* Switch from "rgb" (="subpixel"?) anti-aliasing to "grayscale".

* Uninstall xserver-xorg-video-intel to let the modesetting driver take over.

* Ctrl+Alt+F1 then Ctrl+Alt+F7 (btw, characters in virtual terminals Ctrl+Alt+F1 to F6 are gone as well).

What _does_ work is boot Ubuntu's 3.8.0-35-generic kernel rather than 4.2.0-36-generic or higher (don't have anything in between). But of course that's not satisfactory.

Correcting the above: my latest available kernel without this problem is 3.19.0-32-generic.

This still happens in Ubuntu 16.04, with kernel 4.4.0-34-generic #53-Ubuntu SMP Wed Jul 27 16:06:39 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux.

Hi

Me too. I have to solve it with logoff. VGA Intel driver maybe?
My laptop is a Dell latitude E5440

Also getting this on a 1st gen thinkpad yoga:

To add to the confusion, logging in and out of X _does_ fix everything in X. The "real" terminals on F1-F6 are still invisible though.

Getting this on a Dell XPS 13 also. Only noticed it after a resume from suspend.

So far 3 people have posted their configuration, having the exact same CPU (or rather integrated GPU). With me that's 4.

Uninstalling xserver-xorg-video-intel leads to X crashes after suspend, occurring at a similar rate as otherwise this "character loss" but. Obviously, that's no improvement.

Similar bug for me too, with i915 driver but on HP Envy 6-1260sf (Core i5-337U) with Xubuntu.

In the list of affected applications, we can add Thunar, xfce4-panel and whisker (xfce menu).
Switching to VT-1 does NOT work for me, same for reloading xfwm4.
So Xubuntu desktop is unusable when the bug happens, and it is very hard to save work in progress because all browsing dialog are also affected.
Loggout/loggin restore the font display, but all current unsaved documents are lost.

The bug is only present after some suspend/resume but not always.

Same issue here on multiple dell latitudes E6540 laptops in company (using Ubuntu 14.04.5). And it does happen after resuming from a suspend. Almost every open application is affected with distorted/missing letters. Looks like http://askubuntu.com/questions/584922/how-do-i-fix-fonts-not-rendering-and-missing-letters (intel driver issue?). Only restarting lightdm (or logging out and in again), fixed the situation.

Just use a recent kernel from http://kernel.ubuntu.com/~kernel-ppa/mainline/?C=N;O=D and you are set.

It happened again for me as well. Macbook Pro mid/late 2013.
I personally don't think the mainline kernel is a valid option, since it defeats the purpose of a LTS release.

@Peterpall: what kernel version do you say that I should try?

Hello

I at least have a very similar problem; so close I think it is the (therefore this comment).

I have the latest and greatest of Ubuntu (Gnome) 16.04.1 LTS. (It is an upgrade from 14.04 LTS, but I do not know if this has any effect here). The problem started, for me, this month or late October.

> uname -s -r -v -m -p -i -o
Linux 4.4.0-47-generic #68-Ubuntu SMP Wed Oct 26 19:39:52 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux

All letters have "disappeared" (ie were not visible anymore) from the affected programs, but not all are affected.
In the gnome-terminal it is possible to select the text and where the mouse pointer hovers while selecting you will be able to read the text, but it disappears on next redraw.

Some NOT AFFECTED programs (except menus etc):
- Firefox (so I was able to do this)
- Chromium
- Ubuntu Help
- xterm
- dash (the ubuntu menu)
- google calendar (web-app)
- (The document part of Libre Office Writer)

Some AFFECTED programs:
- Nautilus
- The desktop
- Remmina
- gnome-terminal
- Thunderbird
- ubuntu-software
- (All menus and toolbars etc of Libre Office Writer)
- All except the document part of the document viewer
- eclipse (eclipse-cpp-luna-SR2-linux-gtk-x86_64)
- skype (only the system-bar(?) (uppermost bar))
- dropbox (except the settings dialog box)
- alarm-clock-applet
- gedit (except the document area)

(It seems document areas are generally not affected, that excepts the buffer, or "document area", of gnome-terminal)

The ctrl+alt+F[1-6] ttys seems to have stopped or not started after printing the following text:
--- start of text ---
  lvmetad is not active yet, using direct activation during sysinit
/ev/mapper/ubuntu--vg-root: clean, aaaaaaa/bbbbbbbb files, cccccccc/ddddddddd blocks
_
--- end of text ---
note: the '_' seems more to be like a cursor than an (overwrite) underscore, but it is not blinking. (the 'a's, 'b's, 'c's, and 'd's are numbers. The number of digits are shown by the number of letters.)

I have the same problem on a DELL XPS-13. Only started recently after an update to 16.04 but I'm not sure which kernel was the cause. Doesn't seem to happen every time but is very annoying when it does.

For me the problem disappeared since I upgraded to the mainline kernel 4.8.9-040809-generic (my random pick) from here

http://kernel.ubuntu.com/~kernel-ppa/mainline/?C=N;O=D

as suggested by PeterPall above. Ubuntu runs like a charm, I only had to update my VirtulBox to the 5.1 series.

I've just encounter the bug since I add 'drm.debug=0xe' on the boot command line.
I hope logs could help, it was hard to launch apport-collect because it is impacted too :-(

Hello,

I can confirm that the bug disappears after switching to a newer kernel than Ubuntu's 16.04 main one. 4.8.10-040810-generic did the trick.

4.8 works fine for me, too. All release candidates of 4.9 caused regular system freezes instead. Didn't test the final version of 4.9, though.

Tested the final 4.9 kernel. If "sync to vblank" is active in ccsm it freezes the system at high cpu loads. ...but for all other settings 4.9 seems to be fine, too.

So it could be possible to identify the patch/commit on 4.8 that fixes the
bug ?

If it is, maybe a fixed kernel for 16.04 LTS could be released in main
repository ?

This should be a proper solution than to switch on kernel-ppa which will
never be upgraded by APT (too new) and leaves the user without any security
fixes !

Does anyone known how to reproduce the bug at every suspend ?
I could test different kernel, if I could be sure on how to get the bug.

That would be how fixing bugs for ubuntu is supposed to work:

 - you find a way to reproduce the bug
 - Even if you only know that the bug was fixed within the last 256 commits to the kernel's git repository git bisect will let you test only 8 versions of the source code - and after you testing them it is already able to tell which commit was the right one
 - git format-patch generates a patch
 - you forward the patch to the packager
 - and all is set.

The only thing missing until now is the 1st step: Finding a way to reliably reproduce the bug.

I’m too affected by that bug (some characters missing after 1 of 10 wakeup) since I’ve upgraded to Ubuntu 16.04 (didn’t had that bug on Ubuntu 14.04).

As reported above, it's usually about 1 in 10 or so (or less) suspend-resume cycles. I hate to log out/reboot and lose my work state, so this is really frustrating.

I can participate in some bug-test kernel cycles.

Perhaps we don't know which commit in 4.8 resolves, but if we have enough people - we can do a wide-spread 'bisect' by tasking multiple people to test particular versions, and see if the issue arises over a period of a couple of weeks or such.

Guys, as it was said above, the bug is fixed in linux kernel 4.8.

Hello,

I can confirm that the bug disappears after switching to a newer kernel than Ubuntu's 16.04 main one. 4.8.10-040810-generic did the trick.

Vlad, thanks.
New features in 17.04:
...
Linux kernel 4.9

I see this on my ThinkPad x230. I think it also triggers sometimes with docking/undocking. I did not have this issue on 14.04.

lspci -nn | grep VGA
00:02.0 VGA compatible controller [0300]: Intel Corporation 3rd Gen Core processor Graphics Controller [8086:0166] (rev 09)

Kernel 4.8, which is supposed to fix the problem, may now simply be installed by:

sudo apt install linux-generic-hwe-16.04

Because it is now available through the official hardware enablement stack.

Just installed it. Will see if the problem occurs again.

Just for the record

My Dell Latitude E7440 (Intel graphics card only) experiences the same problem with Xubuntu 16.04 Xenial Xerus (issue was not present in Xubuntu 12.04, and I didn't tried intermediate versions) I tried several workarounds but none seems to work this far.

I updated to Kernell 4.8.0-29-generic with

# apt-get install linux-image-4.8.0-29-generic

That was the latest update available in the repo at the date. It installed successfully. After reboot the Xorg process was using >80% CPU and the computer was even more sluggish than a Windows Vista running in an Intel 80386 (5 seconds delay for a typed char to appear on screen in console).

There is no need to be an Ubuntu expert to conclude that just updating the Kernel is not enough to solve the problem. Maybe I'm missing some extra configuration or also the X-Server/lightdm daemon must be updated accordingly. Also I'm differentiating Xubuntu from legacy Ubuntu because it affects Xfce and Unity.

Cheers!

I was affected by this issue in 16.04 with kernel 4.4 but it seems to have gone away since upgrading to 4.8; it's hard to tell because it is apparently impossible to reproduce on demand, and only happened maybe 1 in 10 times for me after resuming from suspend.

@kyordhel: I am not sure that specific package is enough to fully install kernel 4.8; you should try installing the linux-generic-hwe-16.04 package which will give you the latest 4.8 kernel plus all necessary dependencies - for example if you did not install linux-image-extra-4.8.0-29-generic you may well be missing some modules that are required for decent desktop performance.

It's been 2 weeks since I upgraded from 14.04 kernel 4.4 to 16.04 kernel 4.8 and I haven't had this issue again (which it happened at least once a week).

@longwave Thanks for the tip, as non-linux expert there is yet much
to learn. Il try installing

    linux-generic-hwe-16.04

and hopefully it will never ever happen again. My question would be
why the 4.X|X>4 Kernel is not part of a regular update for 16.04, but
thats maybe out of the scope of this discussion.

Cheers!

For some reason I had a similar problem but when I switched my antialiasing from grayscale to rgba (through unity-tweak-tool) it was fixed. Downside is I have a low-res monitor so text looks slightly colored.

I've encountered this multiple times on my System76 Galago UltraPro, Ubuntu 16.04, kernel 4.4.0-72-generic.

It's been 50 days since I upgraded from 16.04 kernel 4.4 to LTS Enablement Stack kernel 4.8 and I haven't had this issue again.

Nils, please upgrade your kernel as per the bug description:

WORKAROUND / 'FIX' (added on March 9, 2017)
Several people have mentioned upgrading to kernel 4.8 or higher solves the issue. As per #81, you can easily install kernel 4.8 (if you're on Ubuntu 16.04, that is) by running

sudo apt install linux-generic-hwe-16.04

If you are still experiencing this issue after upgrading to kernel 4.8, please report back.

For me updating to the 4.8 kernel fixed this issue but gave me another suspend related issue which I reported here:
https://bugs.launchpad.net/ubuntu/+source/linux-hwe/+bug/1699436

I eventually gave up on it and switched to using hibernate.
sudo pm-hibernate
or
sudo pm-suspend-hybrid

If these work for you there are instructions online for removing suspend from the GUI menu and adding hibernate.

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

Affected by this bug too. Almost daily when coming back from the lunch break i have to logoff and login to have my fonts back...

In the Terminal application some letters was appear.
I've select text area with mouse, copy and paste in text input of this topic. In the browser letters are visible permanently.
In Terminal application if I select text (invisible) with mouse and moving mouse horizontally along text line while left mouse button is pressed, then text appears after mouse pointer.

In the file browser Files text is visible in the column 'File Type'

Still an issue. Text on pages in Firefox and text in Qt applications (for example, TortoiseHg, VirtualBox), Sublime Text not affected.

Some text not just disappear, but rendered as random pixels. Text in menu can change its color from white to black and sometimes after mouse hover it can appears/disappears

Workarround on LXDE, by using lxappearance and select another theme fixes the issue momentary.

setting Antialiasing from "subpixel" to "standard" in gnome-tweaks suppressed the effects of the bug; but it is still a bug.

Run into the same problem, after several hibernation - wake-up cycles.
Discovered recently than this bug is interconnected with corruption of active Xorg/Unity desktop GUI fonts family. In my case that was "Ubuntu*" fonts.

NEW FIX: works for the active user session, without loosing active processes/apps:
need to switch all themes' fonts to other (Verdana, etc.) than the active font set (Ubuntu *).
These are Default, Document, Monospace, Window header font.

One may accomplish this by using "unity-tweak-tool":
$ sudo apt install unity-tweak-tool
$ unity-tweak-tool
Open Fonts section ("abc" icon);
Change fonts;
Then refresh desktop, may need to restart some windows;
Also you may need to restart unity panel:
initctl restart unity-panel-service

Finding permanent fixes probably possible with fonts tweaking:
https://wiki.ubuntu.com/Fonts
Install alternative fonts, than do:
sudo fc-cache -f -v

However the bug could be related to runtime in-memory font cache corruption, and installing the alternative fonts will do nothing with the problem.
