I just tried to follow the step in https://wiki.ubuntu.com/DebuggingXorg, but when I try to restart X it freezes, and when I pgrep Xorg, I get two process numbers. If I try to attach process No 1, I get the following error message:

This GDB was configured as "i486-linux-gnu"...
Using host libthread_db library "/lib/tls/i686/cmov/libthread_db.so.1".
(gdb) attach 5488

A problem internal to GDB has been detected,
further debugging may prove unreliable.

If I try to attach the second process ID, the computer freezes again!

I have to add to my previous post, that when I log off and try to log back in, the computer seems to freeze once the audio gets initialized, because I hear a freezing typical audio loop (just like "zzzzzz"). I don'T know if this helps.

Do I just have to wait for the release of Hardy, or is this a problem related to the proprietary fglrx driver? Is this a problem of my installation, or did you have suimilar problems on your machines running hardy+fglrx(+ati mobility radeon graphics)???
