Comment 161 for bug 495553

A serious problem has just arisen after an update today. I did the update while the system was started, but before logging in (I switched to a text console while the login screen was appearing). Once I logged in, in safe mode, the 2 icons I'd created on the desktop were bouncing up and down, and neither top nor bottom panel showed.

Then I rebooted. The login dialog was bouncing up and down so I could not log in. I was still able to switch to a text console and collect some data.

By the way, the screen resolution seemed to have been set properly, but I'm not completely sure about that.

I've attached a .tgz archive with Xorg.0.log and the output of 'apt-show-versions'.
