Xorg log
(I'm including all of this in the same bug because I feel like it might all
have the same cause; sorry if you'd prefer them to be split up.)
So, a few bad things are happening since the upgrade to 2.20.14:
- VLC doesn't display video.
With the default output mode, 'XVideo output (XCB)', the display is blank with
hardware acceleration enabled (within VLC), and works but with large black
artifacts without. With 'X11 video output (XCB)', video works fine. With
'OpenGL GLX video output (XCB)', I get the artifacts with and without
acceleration.
I don't see anything in VLC's output, but I'll attach it anyway. This also
happens with Openbox (no compositing).
- I see artifacts on composited windows.
These sometimes appear when such windows move or change. I'll attach a few
screenshots for rxvt-unicode ('urxvt corruption (1-3).png').
- I sometimes see artifacts around windows.
When this happens, it happens for every window, but it doesn't happen often.
I'll attach a screenshot ('corruption.png').
- Xine crashes.
If I open Xine, it shows the window, then dies and prints this:
X Error of failed request: BadAlloc (insufficient resources for operation)
Major opcode of failed request: 149 (XVideo)
Minor opcode of failed request: 19 ()
Serial number of failed request: 2635
Current serial number in output stream: 2636
I'll attach a full log.
----
I see these two lines in the Xorg log (full log is attached):
[ 33.265] (EE) intel(0): Detected a hung GPU, disabling acceleration.
[ 33.265] (EE) intel(0): When reporting this, please include
i915_error_state from debugfs and the full dmesg.
In dmesg, I see:
[ 788.928035] [drm:i915_hangcheck_hung] *ERROR* Hangcheck timer elapsed... GPU
hung
[ 788.928052] [drm] capturing error event; look for more information in
/debug/dri/0/i915_error_state
I'll attach the mentioned file (i915_error_state).
I use Compiz without a desktop environment on 64-bit Arch Linux, using a GMA
4500MHD. Installed packages are xorg-server 1.13.0-4 and xf86-video-intel
2.20.14-1.</pre>
