I am having a situation where I logged in to a RHEL 5.6 system and started VirtualBox. After closing the VirtualBox, I am having a situation where the menu bar which has the option to shutdown or lock screen or log off the system is not present. I believe the reason might be due to network load or something.
I can shutdown or restart from the terminal, but again they take considerable amount of time.
All I need is to just Log off from the system when the menu bar is not present. I need to get the login screen like how we have, when we initially boot the system.
Is there any option to just Log off the user using the terminal?
ps -ax | grep dm output
