Ok, To explain a little: Ubuntu users, who have disabled password logins are unable to switch desktop environments due to the fact that the selection menu appears only after "selecting" the user. In the case of no set password, the user selection leads to automatic login.
This is a serious oversight! Ugly fix: add another user with password enabled. Log out, click on the new user name, switch the desktop environment and click on your default user. -- when log off no panel appear if you disable password on log on https://bugs.launchpad.net/bugs/540775 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
