Bug#592586: xserver-xorg-video-intel: Rendering issues: Detected a hung GPU, disabling acceleration



Package: xserver-xorg-video-intel
Version: 2:2.12.0-1
Severity: important

This seems to be triggered by apps using accelerated video or 3d. This time
it was warzone2100 but I've seen it before with just a few terminals and a
web browser.

The first symptom is that the (fullscreen) display of the game seems to freeze.
The mouse cursor is not drawn although I can tell from audible feedback that
the game is still running and keypresses seem to have the expected effect.

I'm using the awesome window manager. Switching to another tag displays the
desktop background fine. The awesome toolbars and widgets are drawn but with
some gaps and any text is quite fuzzy as though being drawn multiple times at
slightly differing pixel offsets. At this point I can see the mouse cursor
again.

Other (less-accelerated) apps show different levels of corruption. For example,
in rxvt, the cursor and any ncurses-drawn widgets are missing, but text is for
the most part ok. xterm on the other hand appears to have no problems at all.

Switching VT and the text framebuffer console seems to work with no issues.

The included Xorg.0.log in the Package-specific info is for X after being restarted
twice. Unfortunately the log for the original problem occurence is gone. After
restarting X once I tried to run warzone2100 again at which point X crashed. The
log for that brief session includes these lines:

I previously reported a similar issue as #582975. That got no response and
the symptoms were different enough that I thought a separate report was in
order.
