Xorg crashes with segfault
Status in xorg package in Ubuntu:
Using Ubuntu 16.04 and a pretty modern workstation. Every once in a
while (some times every other day, sometimes three times a day) X
crashes and I'm kicked out to the login screen.
From Xorg log:

Fatal server error:

It seems pretty similar to this issue:
I understand that this is probably not enough information, but please
let me know what more info you need and I'll try to get it.
