Title:
  Crash of Xorg under intel drm

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  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.
