Public bug reported:
I am using an older Ubuntu mainline kernel with Vivid. The computer I am
using is a Dell XPS 9343 which is known not to do too well with linux,
like most new dell computers. However the only issue that actively
bothers me the fact that Xorg is getting crashed all the time by the
frame buffer drm in the intel driver. This can be observer in this
trace,

I can confirm that the crash occurs in different ways according to
different traces I've read but it would be impossible to compile all of
them. The crashes of the screen are not apparent to any function done on
the user end. They are random and can sometimes be very spaced out or
sometimes happen many times in a row. In order to get the screen working
without restarting lightdm, I have to switch into tty1 console then back
to graphics mode. Hopefully someone knows how to debug this trace better
than I.
