Xorg log file with crash
Using up-to-date Arch Linux (testing), whenever my screens go into suspend, it
causes Xorg to crash with segfault. The bug is triggered immediately when
running 'xset dpms force standby'.
This also affects at least 2 other people, see the Arch Linux bug tracker:
https://bugs.archlinux.org/task/38335
I'm using xorg 1.15.0, xf86-video-intel 2.21.15, kernel 3.12.6, using Intel HD
4000 graphics on i5-3570K. According to the above bug report, xf86-video-intel
2.99.907 also has this problem.
lspci:
00:02.0 VGA compatible controller: Intel Corporation Xeon E3-1200 v2/3rd Gen
Core processor Graphics Controller (rev 09)
Setting AccelMethod to uxa in Xorg configuration works around this problem:

Until now I have been using Xorg 1.14.5 with SNA enabled, which does not have
this problem.
