[fglrx] compiz crashed with SIGSEGV in nux::IOpenGLSurface::UnlockRect()

Exactly the same for me on my acer aspire one 521 with radeon hd4225 - on Ubuntu 10.10

Hello,

Also same behavior with 11.04 alpha, graphic card ATI Radeon HD5770 and 3D proprietary drivers fglrx.

Gnome-classic session works well, no problem, but if I load Unity, I only get the wallpaper, mouse works, I can right-clic on desktop, but no panel, no global menu, no Unity dock...

Also, when I try to restart classic session, I get an error message telling that a program is still running : Compiz - no response.

If I uninstall proprietary drivers, of course when I try to run Unity session, it tells me that I need 3D drivers and loads classic Ubuntu desktop.

Last, I tried to make ubuntu-bug unity on the Unity session with fglrx activated, but had no connection to send the report, do you know where it is saved on my computer to post it ?

Thanks.

This also on ati radeon x1300 /thinkpad t-60

Same Problem on a Toshiba Tecra S1 with the Radeon 9000... As the Chipset is discontinued by the propitary driver it uses the "radeon" driver... I experience this Problem from the very beginning.

same here...hp pavillion notebook running ati mobility radeon hd 4200 series 8.78.3

absolutely confirm this. After trying 2 weeks to get unity running, i just removed fglrx and i have unity again.

Running ATI Radeon 4850 card.

absolutely confirm this. After trying 2 weeks to get unity running, i just removed fglrx and i have unity again.

Running ATI Radeon 4850 card.Using fglrx from regular repos, no ppa's.

Marking as confirmed.

wrong set status to confirmed, i cant set it to triaged .

Ok another interesting fact, this time good news.

Just installed the latest AMD Radeon drivers via xswat ppa and unity is working once again .

You will find nvidia and ati packages here https://launchpad.net/~ubuntu-x-swat/+archive/x-updates

cheers.

Sorry false alarm. The driver from the xswat ppa hasnt been enabled yet on my system, it was using the open source driver hence it was working.

Have been up all night trying to get this to work. :)

In the same computer with different Ubuntu versions I get the following information about OpenGL:

Jay: can you first determine, why it fails. And depending on that, coordinate with the X team to have bugs upstream and/or blacklist

I had attempted loading unity with fglrx last month but also failed to get it going. No idea why it isn't working though... I'd assumed at the time it was a unity bug since I could get classic+compiz running. But I suppose a driver bug is possible.

Alberto is probably the best contact point for this bug since he can escalate it to AMD.

So far it is a no go for the radeon 5000 series, it seems; for radeon and radeonhd drivers with unity. it's only early alpha though, so things will get better as time goes on.

I couldn't find release notes for the 10.12 catalyst driver online, however afaik hd4xxx and hd5xxx *should* work with the current natty setup, so this seems to be a legit bug.

However, note that in the next week or so we'll be uploading a new xserver which will completely break everything for fglrx, due to abi incompatibility. So it will be completely broken very soon regardless.

Felix points out this is being caused by compiz crashing. So it appears not to be an X or fglrx bug but rather something in nux:

The description of the bug (wallpaper displaying properly, popup notices showing and hiding properly) indicates that X hasn't crashed or locked up, and suggest a window manager (compiz) failure. So I'm reassigning this to compiz for further analysis.

It would probably help if someone could gather a full backtrace (with line numbers and such). Run compiz in gdb, and then use 'bt full' to get a full backtrace.

Same problem for me on my Acer Aspire 5542G with ATI Mobility Radeon HD 4570 - on Ubuntu 11.04 Alpha 1.

I'd like to help by reporting logs. Please does someone know where logs are saved after launching "ubuntu-bug unity" ?

Also, what commands to enter in order to "run compiz in gdb, and then use 'bt full' to get a full backtrace" ?

Thanks ina dvance.

run unity --advanced-debug from a VT, it will do the right thing with the export DISPLAY and all. just type 'run' once you see the gdb prompt.

And how to save the output? Running 'set logging on' gives very little information.

Ok, so here it is : http://pastebin.com/kmR7HSvt (backtrace full , info registers , thread apply all backtrace)

#0 0x0000000000000000 in ?? ()
#1 0x00007fffe7436cf0 in nux::IOpenGLSurface::UnlockRect() () from /usr/lib/libnux-graphics-0.9.so.0

#3 0x00007fffe7401545 in nux::CachedTexture2D::LoadMipLevel(nux::BaseTexture*, int) () from /usr/lib/libnux-graphics-0.9.so.0

Not sure what to make of the first null function call, but this seems to be crashing from in nux. I'll close off the -ati task for now. So far this is not looking like an X bug.

The latest backtrace matches Felix's and so it looks like this is a crash in nux not the driver.

If there is something specifically needing to be investigated on the X side feel free to reopen the fglrx-installer task.

now i get...
'you don't have the hardware requirement to run unity. change user session?' or something.

Same thing, and unable anymore to do a right clic on desktop (nothing
happens) to create a terminal link and launch debug testings.

Just the wallpaper and mouse cursor moving...

Hmm, could this be a DRI vs DRI2 limitation?

same here for me latest daily build ati/amd driver wont run on unity blank screen

Reopening fglrx task as this may be a driver issue, all reported cases are using this driver.

[Making bug report private at AMD's request]

I'm not testing on a Ubuntu platform, but I just finished up firing it on openSUSE with FireGL (10.12) and I can subscribe the bug reported. It's exactly the same behavior on a very different platform.

If you have any pointers on how to debug this thing properly, I can try to help.

Ok, to clarify: this happens with the radeon driver too. I try to start unity since the first alpha versions, never got it work. The only thing that has changed is that I get an Info in the latest dailys that my hardware is not supported (ATI X600M). Compiz on 10.10 runs smooth with the free drivers.

Thorsten: You're saying you get a crash in nux::IOpenGLSurface::UnlockRect() when using the radeon driver? Any other problem (like unity telling you you can't use it) is not the same bug.

same for me. after installing the fglrx driver i rebootet the system. then tried to log in to unity. after i had entered my user credentials a windows popped up (before the desktop was loaded). this pop up told me that i can't use unity and asked me to load the ubuntu classic session. i clicked on yes but it seemed that it booted into unity. i only saw the desktop background. no panel and no sidebar and no window decorators. Then the crash report popped up.

Same for me, installed daily-live amd64-20110125 on dell inspiron 1546.
fglrx driver, declined classic to test - pretty wallpaper - no left/right click response - no panel/sidebar/decor.
Mine includes lack of any usb plug working--but that may be another issue?

Rebooted a few times--not getting greeted with the 'I can't' pop-up (a bug or one time deal??), and cruising into pretty wallpaper with no panels.
Un-installed the fglrx driver-rebooted- and desktop loaded w/side, top panels!
Now if I could just figure out how to access 'Apps/Places/System' as easy as 10.04?

I have noticed that the crash happens in IOpenGLSurface::UnlockRect because of a call to glBindBufferARB. I am able to go past these errors but only to fall into more errors laters.
I Also noticed that Unity starts in indirect mode and the version of OpenGL that is use is 1.4. This is the version of OpenGL that is supported by X in indirect mode. We are currently working on a way to improve the situation.

Hello good folks of unity. :)

Alpha 2 is almost upon us fglrx users.Xserver 1.1 is also here which will break X .

My question is, how will this bug be fixed at this stage when fglrx will break anyways with the new X stack.Or will you guys hold out till a new fglrx is out ?Or it is patched ?

Thanks and regards

rajeev

i'm staying away from the fglrx drivers until this situation has been resolved. even if i'm using the standard desktop and not unity. all this talk of x breaking is rather worrying.

I had fglrx installed and used clasic desktop.After yesterday's updates my x dosent work even after removing fglrx...

You probably need to remove your existing /etc/X11/Xorg.conf, since I
believe that it forces that driver to be used in there.

To answer #41 - first, it's "1.10" not "1.1". xserver 1.1 was a LONG time ago. ;-)

Anyway, we've communicated this bug to AMD, and so we will hold out until a new fglrx is released. Use -ati in the interim.

We can't fix/patch the fglrx driver ourselves since it is proprietary.

Unity in Alpha 2 is now working with an AMD Radeon 5450 graphic card and the open source Radeon driver.
However Alpha 2 is not that stable yet.

AMD OpenGL driver doesn’t support GL_EXT_stencil_two_side, but compiz attempts to call to glActiveStencilFaceEXT which cuases segmentation fault, because the API glActiveStencilFaceEXT deosn't exit.

Since this is something between nux and fglrx (dunno if it's the lack of GL_EXT_stencil_two_side or not) I'm closing the compiz task.

Loic, could you please investigate Sunny's findings, I'd like this to be fixed before A3.

After the March 10th updates, this bug now affects Intel Video for me. Same symptoms as above.

I can confirm what Jim Raredon says... this bug now seems to be affecting Intel Graphics (in my case, GMA950 on an MSI Wind U100)

As per https://lists.ubuntu.com/archives/ubuntu-x/2011-March/001065.html you should be able to now manually install -fglrx and then install a PPA version of unity which work together.

Can someone do this install and confirm whether or not this bug still exists with that?

Testing the daily build of unity with the new fglrx: unity_support_test crashes with the following output. http://paste.ubuntu.com/587529/

The XIO error actually comes after the output, they’re just mixed in the log due to stdout and stderr getting flushed differently.

Should I report this on Launchpad, or is it the wrong place for bug reports about the daily build?

Johan:

unity_support_test has been recently rewritten, it's in nux trunk. You can test if it still crashes by downloading that file ¹ and compile it with that command ².

¹ http://bazaar.launchpad.net/~unity-team/nux/trunk/view/head:/tools/unity_support_test.c
² gcc -std=c99 unity_support_test.c -o unity_support_test `pkg-config --cflags --libs gl x11 libpci`

I tested with the unity daily ppa and i did not have compiz on boot and was dropped to classic desktop.Manually typing compiz --replace in terminal made unity appear but i also had the gnome panel at the bottom.

ALT TAB also seemed very sluggish.

Loïc,

The version of unity_support_test in the nux repo seems to work fine.

Just got Beta 1 and installed the updated fglrx driver. (It was not installed already). The Unity shell resembled a number of 'black squares' jumbled up on the screen. While Unity/Compiz were running other applications flashed as well. However, when I ran sudo killall compiz, all the other apps that were open stopped flashing.

Additionally, when using the standard Gnome 2.x desktop, there is no flashing whatsoever despite the fact that compiz is running.

Just installed 11.04 beta1.. works fine on first installation... My bluetooth was not working so I checked the additional drivers.. I saw that in addition to bluetooth driver, my graphics was not activated. So I activated both.. Later, it ask me to restart the machine... and the things went worst... NO UNITY only BLACK SCREEN....

Somehow I logged out and login to classic ubuntu.. gnome works fine... It seems to me the problem of graphics driver.. I uninstalled it after loogin via classic ubuntu... restart... and unity comes back :)..

For me everything is working fine.. but I think there might be some issues because my machine becomes very hot and the fan keeps running... I think its overloaded... !!!!

By th way my graphics card is ATI 54series..

With compiz version 1:0.9.4git20110322-0ubuntu5, the desktop is unusable due to black squares appearing all over the place. Using version 1:0.9.4git20110322-0ubuntu6+r2723+201103301010 from ppa:unity/daily does fix it. This makes unity usable with fglrx.

I recorded this video to see if anyone in #ubuntu+1 was having the same problem with ATI on Ubuntu 11.04 Beta 1. It doesn't add much to the bug report other than illustrating the black box thing that John, Tushar and Guilluame describe above.

Still having this problem on MSi WInd U100 with Intel graphics

@Francisco
the bug report status is "Fix committed". You'll get the fix when it says "Fix released".

It's already fixed for me as of this morning! :)

Cheers,

@Alberto: can you mark this fix releaed as well, since we received the new fglrx driver that fixes the problem.

Is the black box problem mentioned by John Oliver #57 fixed

Quote:

Just got Beta 1 and installed the updated fglrx driver. (It was not installed already). The Unity shell resembled a number of 'black squares' jumbled up on the screen. While Unity/Compiz were running other applications flashed as well. However, when I ran sudo killall compiz, all the other apps that were open stopped flashing.

Additionally, when using the standard Gnome 2.x desktop, there is no flashing whatsoever despite the fact that compiz is running.

I'm running 11.04, 2.6.38-7. upon installing ATI/AMD FGLRX from Additional Drivers I got this problem mentioned above as well. It looks like the Panels are all black yet the desktop and non moving parts of application windows appear normal. Moving parts like loading bars are black as well.
I have a ATI Radeon HD Mobility 5650. My Laptop Serial is A665D-S6509.
