I can confirm that since I installed bash (3.2-0ubuntu17) All choices in mu user list have disapeared. Nevertheless I did not notice any crash or hang when switching users ....
On one of my computers, I installed back the previous bash version (3.2-0ubuntu16) and the list is again filled with autorized users... Hope it can help .... -- Log off or switch user causes system to hang https://bugs.launchpad.net/bugs/229400 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
