[Bug 982889] Re: X trying to start before plymouth has finished using the drm driver

[Bryce Harrington]

@Franck, yes the bugs belong in the same general class of issue (race
condition with drm), but the stacktraces and code paths differ so the
patch does not address the type of fault you saw.

Title:
  X trying to start before plymouth has finished using the drm driver

Status in “libdrm” package in Ubuntu:
  Triaged
Status in “linux” package in Ubuntu:
  Confirmed
Status in “xorg-server” package in Ubuntu:
  In Progress

Bug description:
  X server fails to start the first time after boot, it works fine when
  I start it again.

  Looks like a race condition with intel drm initialization, i guess X
  tries to start faster than drm driver is initialized so it fails.
