The fact that you can log in as root doesn't mean you should. GDM doesn't show the root user, and the root account is disabled by default on Ubuntu, so you must have found this idea by yourself.
AFAIK, recovery mode only starts a console, so, yes, you should either fix things from the console, or run a graphical session as a normal user. If you're able to run a session as root, you may as well run it as a normal user with admin rights. There's no reason to run a X session as root as it is dangerous and doesn't make anything possible that you can't do as normal session after authentication via PolicyKit. So, maybe logging in graphically as root should be forbidden, yes. If so many people are upset by this silly bug, just provide a patch, it might be a really simple bug. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/643153 Title: users-admin hangs when run as root -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
