The new ATI drivers do not fix the problem, at least for the 64-bit version of Dapper. I installed the 64-bit version of the fglrx 8.26.18 driver, and I have exactly the same problems as I described in much greater detail further up this thread: With the fglrx driver I get a hang every time I shut down, reboot or log in out twice. If I switch to the "ati" driver, there is no hang. Switch back to "fglrx" and the hang reoccurs.
So the 8.26.18 driver does _not_ fix the bug for the 64-bit version of Dapper. -- Lockup problems with both the free xorg ATI driver and the proprietary fglrx driver, using various ATI cards https://launchpad.net/bugs/30447 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
