/sys/class/drm/card0/error
I have Ubuntu Trusty (actually Mint based on it), running Mate and Compiz:
uname -a
Linux kolya-laptop 3.13.0-27-generic #50-Ubuntu SMP Thu May 15 18:06:16 UTC
2014 x86_64 x86_64 x86_64 GNU/Linux
lspci | grep VGA
00:02.0 VGA compatible controller: Intel Corporation 3rd Gen Core processor
Graphics Controller (rev 09)
I get this in dmesg from time to time:
[176923.802692] [drm] stuck on render ring
[176923.802696] [drm] GPU crash dump saved to /sys/class/drm/card0/error
[176923.802697] [drm] GPU hangs can indicate a bug anywhere in the entire gfx
stack, including userspace.
[176923.802698] [drm] Please file a _new_ bug report on bugs.freedesktop.org
against DRI -> DRM/Intel
[176923.802699] [drm] drm/i915 developers can then reassign to the right
component if it's not a kernel issue.
[176923.802699] [drm] The gpu crash dump is required to analyze gpu hangs, so
please always attach it.
Machine freezes for a bit when this happens. Sometimes some letters on the
screen got garbled - i.e. one particular letter on every window gets rendered
in broken way.
Error contents attached.
Please let me know if I can provide any other information.
Thanks.</pre>
