Red Hat Bugzilla – Bug 522742
Xorg crashes intermittently when compiz is enabled
Last modified: 2009-09-17 08:17:21 EDT
Description of problem:
After today's set of updates, Xorg now crashes when a user logs in. If I install gnome-power-manager, everything works fine. I have removed gnome-power-manager because of some problems with it turning off the monitor when we don't want it to, and our school policy is that the monitor is on if the computer is on (it helps us know which computers are on and which are off in the labs).
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Remove gnome-power-manager
2. Log in

I'm afraid I jumped the gun when I assumed that it was a problem with gnome-power-manager. It appears that it's an intermittent problem. If I log in *immediately* after gdm loads up, everything works. If I wait a few seconds, Xorg segfaults during the login.
I do have custom files for /etc/gdm/Init/Default and /etc/gdm/PreSession/Default, which I will attach. They do things like start x11vnc as root and, on PreSession, kill gnome-screensaver.

Ok, I've tracked it down to compiz being enabled. If I disable compiz, there are no problems at all. Not sure what the issue with compiz is, but there it is. Again, if I log in immediately after gdm starts, everything works fine with compiz. If I disable compiz, everything works fine. If I have compiz enabled and login 15+ seconds after gdm starts, Xorg crashes.
I'm seeing the same thing, though I don't even get 15 seconds.
uninstalling compiz seems to fix the problem. (sigh). I really like my desktop effects....;(
Same here, I don't think I even get 15 seconds. Changing the window manager from compiz-gtk to metacity allows me to login again. I'm seeing messages about X segfaulting in /var/log/messages:
Sep 11 09:30:04 maunalani kernel: Xorg: segfault at 0 ip 00000000004e8e0b sp 00007fff8623e158 error 4 in Xorg[400000+1b6000]
I'll try to get a backtrace from X when running compiz --replace.

Same here. Downgrading xorg-x11-server-Xorg-1.6.3-4.fc11.x86_64 to xorg-x11-server-Xorg-126.96.36.1991-1.fc11.x86_64 seems to solve the issue, and compiz works.
This bug is critical. Without graphical login, users can not even run PackageKit to download an update.
I'm the poster of bug 522863, so I'll reply to Gabriel Ramirez's questions here:
> if you add nomodeset to the kernel 2.6.30 options line can you after that enable desktop effects???
nomodeset didn't seem to make any difference. (I've been seeing the "[drm:edid_is_valid] *ERROR* Raw EDID:" errors for a while before this)
> or boot previous kernel 2.6.29 with desktop effects enabled???
I hadn't knowingly disabled desktop effects when booting to the previous kernel. After the first replies on 522863 I disabled it (while runnning on the older kernel) and booted into 2.6.30 okay. The desktop immediately crashed on enabling desktop effects. Now when I try to enable desktop effects on the older (previous 2) kernels the desktop crashes. However at the very least I did boot into a 2.6.29 kernel to disable desktop effects and I had been using them previously, so something seems to have changed.

I was betting which with nomodeset you will have 2.6.30 with Desktop Effects enabled, but seems wrong.
because I have kernel kernel-188.8.131.52-43 working with xorg-x11-server-Xorg-1.6.3-4 and desktop effect enabled in two intel machines
I has running that xorg-version running under kernel 2.6.29 as by https://bugzilla.redhat.com/show_bug.cgi?id=518532#c5 but with mesa7.5.1 and libdrm 2.4.12 and intel driver 2.8.1
if your intel configuration don't have any xorg.conf, maybe you want to try install my rpms to see if them solved the bug
Reproduced the problem on my ThinkPad T400 with Intel graphics as well running F11 x86_64.
Downgrading to previous version of xorg-x11-server-Xorg also worked for me. Fortunately, I do not login with Desktop Effects or Compiz enabled by default. Instead, I use the Compiz Fusion Icon to launch Compiz as a post-login step. With the latest version of xorg-x11-server-Xorg, X crashes only when trying to launch Compiz. I'm attaching a copy of my Xorg log file for reference (as Xorg.0.log.broken)

if your machine don't any xorg.conf and try my rpms drop this file myrepo.repo in your /etc/yum.repos.d, and run yum update --enablerepo=myrepo that will:
will downgrade to mesa 7.5.1 because a leak memory bug fixed in http://intellinuxgraphics.org/2009Q2.html bug#20704 described in https://bugs.freedesktop.org/show_bug.cgi?id=20704
to intel driver to 2.8.1
to libdrm-2.4.12-0.9 recompiled for F11 from F12
glew-1.5.1-3.fc11.x86_64 recompiled for libdrm 2.4.12
to mesa 7.5.1 because a leak memory in mesa 7.6 bug fixed in http://intellinuxgraphics.org/2009Q2.html bug#20704 described in https://bugs.freedesktop.org/show_bug.cgi?id=20704
also look to update to xorg-x11-server-Xorg-1.6.3-4 from fedora because is required by the intel driver 2.8.1 by http://lists.freedesktop.org/archives/xorg/2009-August/046978.html in "New fixes in 2.8.1 compared to 2.8.0"
write down the list of packages updated for if the problem persist in your case can run yum downgrade the list of packages updated
Happens immediately without compiz here. No logon possible.
Custom 184.108.40.206 kernel, radeonhd from git.
Gabriel's repo works for my Intel G965.

> Gabriel's repo works for my Intel G965.
can you tell if that is with desktop effects enabled and Kernel modesetting active with kernel-220.127.116.11-43.fc11??
I will remove a kernel-18.104.22.168-45.fc11 which I has in my repo I forgot about it, but can cause problems because no kmod from rpmfusion are built against it.
the kernel-22.214.171.124-45 is removed
Your packages work with Desktop Effects and KMS enabled on the main/older kernel.
well thanks, so maybe an update to one or more of the following packages is necessary to work with xorg-x11-server-Xorg-1.6.3-4:
xorg-x11-drv-intel-2.8.1 the showstopper to this is which don't support or XAA EXA, only UXA so maybe don't work where EXA or XAA is specified in the xorg.conf
but my two computers don't have any X freezes with it
libdrm-2.4.12-0.9 intel driver required a version >= 2.4.11 but the .12 from F12 compiled fine at the time so I use it
mesa-7.5.1-0.4 have a fix to a memory leak which affted one of my two machines
all SRPMS are in myrepo too so can be downloaded with:
yumdownloader --enablerepo=myrepo --source xorg-x11-drv-intel mesa
and are based in Fedora rpms
I have the same problem. Intel G45 Graphics Set. Disabling compiz fixes the problem.
Additionally since the kernel 2.6.30 update i get a X Login Screen with a
a ~90pt font. This does not happen with older kernel releases.
I'm not quite sure if this is related. If it's not i can open an extra bug for this.

do you want to try updated packages of intel driver, mesa and libdrm? described in comment #14 maybe fix your issue with Compiz https://bugzilla.redhat.com/show_bug.cgi?id=522742#c14

I uploaded the file with the repo enabled by default, so always will update
please change the line

repofile disabled by default containing a location with rpms which maybe fix this bug
I uploaded a corrected repofile disabled by default so execute:
yum update --enablerepo=myrepo
and will update to intel driver, libdrm and mesa only with the option --enablerepo specified
again be sure to update Xorg-1.6.3-4 from fedora because is

This seems to be the same issue as this bug: https://bugzilla.redhat.com/show_bug.cgi?id=518748
latest xorg update renders many fedora users unable to use fedora, this is really, really bad!
I agree with comment #24, this should be closed as duplicate of bug 518748.
https://bugzilla.redhat.com/show_bug.cgi?id=518748#c50 says that a fixed X server is on the way.
The updated packages in https://bugzilla.redhat.com/show_bug.cgi?id=518748#c50 fixed it for me.
