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

[Bryce Harrington]

Thanks for the logs.

Unfortunately neither of these match the OP's sequence of events, and
thus does not hit the problematic drm loading race that the original
reporter was seeing.  So, not surprising that this patch does nothing
for your cases.  I'd like to see someone who has Thomas' bug to test
this.  Specifically, if on startup you see in /var/log/Xorg.0.log a
sequence of messages like this:

[     2.555] drmOpenDevice: open result is 9, (OK)
[     2.555] drmGetBusid returned ''
[     2.555] (EE) intel(0): [drm] failed to set drm interface version.
[     2.555] (EE) intel(0): Failed to become DRM master.
[     2.555] (II) intel(0): Creating default Display subsectio

Then it's worth testing the patch in the PPA, and I think it will fix
that case (or at least give us more specific data).

@Adam, I'd want to see the Xorg.0.log from the first boot, when you get
dumped into low graphics mode.  And maybe Xorg.0.log.old.  The log you
posted appears to be from a successful session so that doesn't
illuminate why the failed session failed.

@Franck, it's possible your bug (#1129220) is distinct and was
incorrectly duped here, but it does seem that your issue belongs with
this general "class" of problems.  However I think a different kind of
fix will be needed in your case.

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.
