Title:
  [xmir] Xorg crashed with SIGABRT in main_arena()

Status in xorg-server package in Ubuntu:
  New

Bug description:
  Enabled XMir (installed unity-system-compositor on a Saucy system) and
  booted.  My system is a Lenovo T410s laptop in a dock connected to an
  external 2560x1440 monitor.  I booted up with the laptop closed
  (internal panel off), and the login screen came up on the external
  monitor correctly.  I logged in and the desktop came up in 1280x960
  mode (*NOT* my monitor's native resolution).  I opened up the Displays
  control panel, switched the monitor to its native 2560x1440 resolution
  and clicked apply.  The screen went blank and I was dumped back to the
  login screen -- X apparently crashed.

  The impact here is that XMir is unusable for me -- I'm definitely not
  running my monitor at a distorted 1280x960 mode when it should be
  doing 2560x1440!  (And I guess I should mention that the normal X
  stack works perfectly for me)
