Finding out why Ubuntu desktop with Gnome2 freezes


Hi all,

Lately my desktop just freezes, completely. No keyboard response, no mouse response, nothing but hard-reboot helps. I can't even SSH it from another machine to try and analyze or gdm restart it.

Can you suggest where to start looking?

Running Gnome 2.32.1 on Ubuntu 11.04 (Natty)

Hardware details (lshw -short)
Code:

Does it work in recovery mode?
Try to fix broken packages.

sudo dpkg --configure -a
sudo apt-get install -f

Well, most of the time the desktop works well in regular mode, for example, today it hasn't frozen (yet :-) ) so I haven't tried running it in recovery mode.

I've tried fixing broken packages, but there aren't any...
Code:
karnaf@myhost:~$ sudo dpkg --configure -a
[sudo] password for karnaf: 
karnaf@myhost:~$ sudo apt-get install -f
Reading package lists... Done
Building dependency tree       
Reading state information... Done
0 upgraded, 0 newly installed, 0 to remove and 11 not upgraded.
When it gets stuck, is there a chance I can find anything in any log after restarting it?

Thanks for the help!
