<pre>Bug description:
If I switch the screen off (e.g. xset dpms force off, entering standby,
xscreensaver, etc), the screen does switch off, but X becomes stuck in
uninterruptible sleep. This ONLY happens if I have been playing gzdoom (+brutal
doom mod) with hardware acceleration prior to that.
I have no choice but to forcibly reboot the machine when this happens, because
not even SIGKILL can kill it. ps reveals:
PID COMMAND STAT WCHAN
2200 X Ds+ intel_finish_fb
It is stuck in intel_finish_fb.
System environment:
-- chipset: Intel GM45
-- system architecture: 64-bit
-- xf86-video-intel: 2.20.13, 2.2.15 also tested
-- xserver: 1.13.0
-- mesa: 9.0
-- libdrm: 2.4.40
-- kernel: gentoo-sources-3.5.7
-- Linux distribution: Gentoo
-- Machine or mobo model: Lenovo Thinkpad SL510
-- Display connector: LVDS @ 1920x1080
Reproducing steps:
-Play gzdoom with BD mod for a few minutes
-Quit game
-xset dpms force off
-display switches off and X stuck
Additional info:
No suspicious kernel log or Xorg log.
xorg.conf:
Section "Monitor"
Identifier "<default monitor>"
DisplaySize 344.16 193.59
EndSection
Further testing in progress.</pre>
