Muon desk is frozen

In case the muon desk becomes frozen attempt to kill the X Server with Ctrl+Alt+Backspace. If this does not help, ask the run control shifter or shift leader to reboot the machine via ipmi, they have instructions and the privileges to do so. Report it in elog ticking CSC+MDT+RPC+TGC+ SysAdmins as affected system. Please avoid calling the sysadmins on call outside normal working hours if possible, if needed use one of the other muon desks in the meantime.

Muon menu is missing on the muon desk

This is usually since somebody has started the X-session not with the muon profile. Log out of the session (from the button in the bottom left of the desktop), when the login screen appears re-login as user crmuon, no password and select Muon:Shifter as profile when asked ....

Muon desk shows the login screen

This can happen after a user logged out or after a reboot. Login as crmuon - not your personal account! - , no password and select Muon:Shifter as profile when asked
