I have the same problem. Now I'm using Edgy but the problem existed also in Dapper. Graphics card is Radeon 9000 pro:
01:00.0 VGA compatible controller: ATI Technologies Inc Radeon RV250 If [Radeon 9000] (rev 01) 01:00.1 Display controller: ATI Technologies Inc Radeon RV250 [Radeon 9000] (Secondary) (rev 01) The problem appears, when I log out and move mouse cursor to bottom or right edge of the (login) screen. Restarting X-server (ctrl+alt+backspace) "fixes" the problem. Sometimes also switching to text console (ctrl+alt+f1) and back helps. -- login screen crashes https://launchpad.net/bugs/42157 -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
