Xorg logs, vmstat, and dmesg output.
I have had this problem on rare occasions over the last-year, when CPU or
memory resources are in heavy use, but been unable to reproduce it. Recently I
can reproduce it consistently by triggering firefox bug:
<a href="https://bugzilla.mozilla.org/show_bug.cgi?id=1165624">https://bugzilla.mozilla.org/show_bug.cgi?id=1165624</a>
On triggering the Firefox bug, Xserver becomes nearly or completely
unresponsive to user input, after which either Xserver fails, or hard-reboot is
required.
The following is consistently triggered:
(WW) intel(0): Failed to submit rendering commands, trying again with outputs
disabled.e
(EE) intel(0): Failed to submit rendering commands, disabling acceleration.
Followed either by a segfault or a bus error.
