Oh, one other thing: with the older kernels I can play AssaultCube
again!  I couldn't really do that with the current Vivid kernels because
the frame rate was too low.  Reported frame rate would be around 60 fps,
but it looks more like 10 fps.  With these old kernels it plays
smoothly.

Title:
  Screen resolution no longer works

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  My display's native resolution is 2560×1440 pixels.  Prior to, I
  think, Saucy I could only reach this resolution by adding it using
  xrandr, and then calling xrandr on boot/login to select that
  resolution.  The Display preferences did not show any higher options
  than 1920×1200.

  In Saucy, the native resolution just worked, and I could stop using
  xrandr.  It also worked in Trusty in the alpha releases, up to (and I
  think including) beta-1.  But today (this is not an April's fool, is
  it?) I rebooted after an upgrade, and found myself back in 1920×1200.
  Again, the Display preferences list that resolution as the highest
  possible.  But this time, attempts to ‘xrandr --addmode’ my native
  resolution failed.

  The error message wasn't very helpful; I'll try to reproduce it later
  but it throws my display into yet a lower resolution that's hard to
  work with.
