Description Guy Maurel 2013-08-28 16:25:08 UTC 
https://bugs.archlinux.org/task/36707

Xorg crashes just after using git gui&
As making a "commit", "push" "push"
I get an "OK" message from the git-server
About 5-10 seconds after, most of texts from git gui window become as a black rectangle.
At the same time, I use firefox to make a (kdepim/akonadi) review.
The black rectangles came also instead of texts in the firefox window.

I use:
firefox 23.0.1-1
git 1.8.4-1

This seams to be not relevant. Even with
firefox-22.0-1
git-1.8.3.4-1

More, the problem seams to be with the use of xf86-video-intel-2.21.14-2

Downgrading to xf86-video-intel-2.21.12-1

is a workaround for me.

No Xorg.0.log? Bonus points for finding the one with the crash message.
Comment 2 Chris Wilson 2013-08-28 16:46:11 UTC 
Reading your description there is no crash, and not much to indicate the exact nature of the bug.

Xorg.0.log and dmesg are essential starting points.

the X logfile as it crashes
Comment 4 Guy Maurel 2013-08-28 18:06:26 UTC 
Right!

After the black rectangles appear it takes about 5 until Xorg crashes.
Comment 5 Chris Wilson 2013-08-28 18:14:16 UTC 
Looks like it should be a GPU hang, anything in dmesg and /sys/class/drm/card0/error (or /sys/kernel/debug/drm/0/i915_error_state)?
Comment 6 Guy Maurel 2013-08-29 17:17:41 UTC 
nothing in dmesg
file /sys/class/drm/card0/error doesn't exists
or /sys/kernel/debug/drm/0/i915_error_state doesn't exists but
/sys/kernel/debug/dri/0/i915_error_state which says:
no error state collected

The use of a file /etc/X11/xorg.conf.d/20-intel.conf with
      Section "Device"
        Identifier  "Intel Graphics"
        Driver      "intel"
        Option      "AccelMethod"  "uxa"
      EndSection

is a solution. The crash doesn't occur any more.

More on I produce the crash:
login as user_1
switch user

login as user_2

Start firefox and login in https://git.reviewboard.kde.org
  look for some of my messages
Open a terminal
  git gui&
    to get informations about the changes I have made before
    choose some files to make a commit, write some text for the commit
    commit
    push
      in the "push"-Window push
      after some seconds I get a message "OK"
      OK
wait some seconds, ... crash
Comment 7 Chris Wilson 2013-08-29 17:57:31 UTC 
Do you have a crash reported in any logfile?
Comment 8 Chris Wilson 2013-10-11 10:31:07 UTC 
Sorry, I lost track of this bug and never helped you get the actual crash log.
