I can't switch user from the Unlock screen dialog box (which is what comes up when I select "Switch From ..." in the power button drop down), I get same result.
If I look in the system monitor at the processes running there is no sign of gdm, which seems wierd (to me anyway) so I tried running gdm from the command line and got the following output ..... ** (gdm-binary:9795): WARNING **: Failed to acquire org.gnome.DisplayManager: Connection ":1.140" is not allowed to own the service "org.gnome.DisplayManager" due to security policies in the configuration file ** (gdm-binary:9795): WARNING **: Could not acquire name; bailing out -- Switching users does not work in 10.4 https://bugs.launchpad.net/bugs/597581 You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gdm in ubuntu. -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
