Same situation here. The lock-up doesn't happen every time, though. I moved from Dapper to Edgy using the apt-get dist-upgrade route.
I've tried to dpkg-reconfigure xserver-xorg, no noticeable differences: sometimes it reaches the kdm login screen, sometimes complete lock-up. After this, I've replaced the "ati" driver in /etc/X11/xorg.conf by the "vesa" one and it hasn't hung again, but just tried a few times. -- xorg.conf completely locks machine https://launchpad.net/bugs/55844 -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
