    That sounds like a real bug.

    Could you attach your /var/log/kdm.log and /var/log/Xorg.0.log.old files, perhaps?

    these are from Xorg.0.log.old

    is it caused by ATI drivers?

    I'd wager it's the videodriver, yes. The X backtrace is pretty useless though, and I'm not familiar with AMD cards and their drivers. Have you tried the proprietary Catalyst? And is fglrx the same as xserver-xorg-video-radeon?

    That said, you could add the bleeding-edge xorg-edgers ppa (ppa:xorg-edgers/ppa) and upgrade to the fresh versions of X and drivers available from there. But obviously there are no guarantees with regards to stability. Caveat installer. Downgrading back is pretty easy though with the ppa-purge tool.
    Code:
    $ sudo add-apt-repository ppa:xorg-edgers/ppa
    $ sudo apt-get update
    $ sudo apt-get upgrade
