/sys/class/drm/card0/error log
I just installed Linux Mint Qiana 64-bit on a stock Dell Inc.
Vostro1510/0R780K. The primary laptop display (not hooked up to any monitors)
will go black, and is seemingly unrecoverable without reboot.
I can reproduce the issue every time when opening up Firefox and attempting to
go to the Google Chrome website.
The kernel is 3.13.0-24.

[Tue Oct 7 23:12:42 2014] [drm] GPU crash dump saved to
/sys/class/drm/card0/error
[Tue Oct 7 23:12:42 2014] [drm] GPU hangs can indicate a bug anywhere in the
entire gfx stack, including userspace.
[Tue Oct 7 23:12:42 2014] [drm] Please file a _new_ bug report on
bugs.freedesktop.org against DRI -> DRM/Intel
[Tue Oct 7 23:12:42 2014] [drm] drm/i915 developers can then reassign to the
right component if it's not a kernel issue.
[Tue Oct 7 23:12:42 2014] [drm] The gpu crash dump is required to analyze gpu
hangs, so please always attach it.
