--- Comment #11 from Jens <jens-bugs.freedesktop.org at spamfreemail.de> ---
I have not yet managed to reproduce it with "nomodeset", but I also cannot
start X with this parameter, no matter if cleanly or after a resume. The
lightdm background starts up, but that is it.

Even more strange, when I switch to VT1 (Ctrl-ALt-F1) and back, the VT1 text
with black background stays on the screen but I can reveal the X lightdm
wallpaper bit by bit by "drawing" on the screen with the mouse cursor.

Restarting lightdm after a resume crashes the system (keyboard frozen). No
errors in dmesg.
