Package: lightdm
Version: 1.10.2-1
Severity: important
After logging out, I got a black screen with a frozen mouse pointer.
I could still switch VT's, but VT 7 (and 8, and 9, just in case)
only showed a black screen. I had to reboot.

I suppose the "resize called 1920 1200" occurs after logging in, since
this is what I do at this time.

The "service dbus restart" is actually not supported by dbus and is
a bad advice from the checkrestart utility.
So, I'm closing the lightdm bug, which seems to either be obsolete
(unreproducible) or come from unsupported dbus restart.
