Title:
  intel 915 graphics fails to detect monitor resolution

Status in “linux” package in Ubuntu:
  Confirmed

Bug description:
  What should happen:

  Upon login, an external monitor connected via displayport to the
  laptop should be detected correctly and the screen size should be set
  to the correct resolution. Further, if the display sleeps, it should
  restore back to the previous state before powering off/sleeping the
  display.

  What happens:

  Starting up with an external monitor connected over displayport, the
  login screen is the correct resolution.  After logging in, it reverts
  to the same resolution as the laptop display and dumps a trace in
  dmesg.

  The resolution can be fixed by use of xrandr, but doesn't work 100% of
  the time.  Further, after the display sleeps, very often the display
  port never wakes up and no longer functions without removing the
  displayport cord, replugging and then re-running xrandr with the
  correct resolution.

  Here are the relevant dmesg bits.
