Description Dominique Leuenberger 2015-05-11 07:52:55 UTC

It seems to happen in a couple test runs on openQA, that X cannot be started by gdm.

Such a test run example is https://openqa.opensuse.org/tests/61970

The journal contains this error:

> May 11 03:25:41 linux-csza /usr/lib/gdm/gdm-x-session[1280]: Fatal server error:
> May 11 03:25:41 linux-csza /usr/lib/gdm/gdm-x-session[1280]: (EE) xf86OpenConsole: Cannot open virtual console 7 (Permission denied)

Considering that re-running the test generally works, this seems to be a racing condition at one point.

So let's reassign to GNOME component ...

My next one to tackle...

After studying the journal of failed and successful boots, it becomes apparent that in failed state:

- starting service gdm... done
happens WAY after X already died on us.. which means: 'something' else (which does not know about logind!) started X for us beforehand, resulting in the permission denied error.

The log also shows "Started X Display Manager", which indicates xdm.service has been started up.

Let's mark this as DUP of 939594

The fix has been found in the package xdm.
