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.
Excerpt of the lightdm.log.old file:

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