Thank you for your bug report. Unfortunately you are going to have to provide more information about the problem before anything can be done about this bug. Please provide a more detailed description of what the problem is.

Isn't this the same as 516520 ?

cheers
Tom

Tom, I agree though it is hard to tell with such little information in the description.

CristainCantoro, I am just going to mark this as a duplicate, please comment if you disagree.

Sorry to be late in my answer. I don't know if this problem is the same as bug #516520.
I get to login screen quite normally (I get some warning while booting but this was happening also before this problem showed up). In the login window I notice the option "session" is missing, then after login I am in failsafe mode (but I did not boot in failsafe mode) having only xterm. X is working, i.e. I can launch programs normally (I even watched a video using vlc, to say... but no sound) but the windows doesn't not have the title bar, and I can't move/resize,minimize them. If I launch a program a window just appears in some spot where it is doomed to stay with a definite size (this differs between different programs, I think this depends on some predefined configuration of said programs). So I thought it was a gdm problem. I can provide any information you want (I can connect to the internet from terminal and use firefox) if you can guide me I will be happy to help.
This problem seems not to be kernel-related since I tried booting another kernel (2.6.31-14) and got the same behavior.
Tried to reinstall gdm (using aptitude) but nothing changed, please note that my system is fully updated.

I have to say that besides the fact that I haven't had any login problem I am getting most of the errors Tom is getting while running sudo gdmsetup (see bug #516520) and I (too) can't unlock the window that appears. So, I finally believe this is a duplicate of bug #516520
