Public bug reported: Binary package hint: gdm
When I attempt to switch users, the system hard locks (i.e. The only way to free the system was to hit the reset button). Specs of possible interest: 1. Ubuntu Dapper with all the latest patches (Upgraded from Breezy). 2. ATI Radeon 9800 pro with official drivers. 3. Athlon 1800 processor. Steps leading to the issue: 1. I log into my default account (The one I created during installation). 2. Once the desktop is available, I Select: "Quit...", "Lock Screen". 3. I have the "Blank Screen" screensaver active, so I move my mouse to get the password dialog. 4. I select the "Switch User" button. 5. I select the user account I wish to activate. 6. The screen switches to tty 8 and then the system locks. Note 1: I've tried the following in response to the system locking: 1. Ctrl-Alt-Backspace 2. Ctrl-Alt-Delete 3. Ctrl-Alt-Fn(N) - Where 'N' is all of the function keys. None of the above produced any results. In fact the keyboard indicator lights have all been disabled at this point. Note 2: I can reproduce the locking sequence by typing: gdmflexiserver -s Note 3: If I attempt to switch users without locking the screen, I am successful roughly 1/3 of the time (i.e. sometimes the system locks, and other it works as desired). Note 4: Typing: "gdmflexiserver --debug --xnest" produces no errors and brings up a nested login. ** Affects: gdm (Ubuntu) Importance: Undecided Status: Unconfirmed -- Switch user crashes system. https://launchpad.net/bugs/76902 -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
