Title:
  100% cpu in Xorg when xorg is started via lightdm

Status in “lightdm” package in Ubuntu:
  Incomplete

Bug description:
  I see Xorg using 100% cpu when its running via lightdm.

  This is not the case if I start X via "startx" or when its run from lxdm or gdm. A strace from a VT shows constant activity (where gdm has only a select() waiting). Most notably this repeats:
  """
  select(256, [0 1 3 5 13 24 25 26], NULL NULL {417 413000}) = 1 (in [0], left {417, 412998})
  read(0, 0x7ffff2bef74a0, 1024) = -1 (Bad file descriptor)
  """
  (transcripted from the affected machine).
