How to enable "switch user" in Gnome on CentOS 5
At my work I have reasonably fast Linux workstation running CentOS 5. It also has a good 24" screen. I prefer not to switch it off between work sessions and sometimes one of the other guys would like to run his stuff on my machine.
Problem is I am logged in and the screen is locked with my password. My colleague is running Ubuntu and he has a nifty "switch user" option on the menu.
Now I have figured out how to get the same functionality in CentOS 5. You need to follow these steps.
Install the Gnome configuration editor. Start "Add/Remove Software" from the "Applications" menu
and search for "gconf".
Select gconf-editor and apply.
Then start gconf-editor from the command line:
Select "Find" from the "edit" menu:
Search for "user_switch" and rember to also search in keys:
find the key user_switch_enabled in the top right pane and tick its value:
Close the editor (there is no save button or command).
Now select Lock Screen" from the "System" menu.
The password box will now have a "Switch User" button! remember that the user you're switching to must also have his settings changed as above to get a "Switch User" button from his or her account.
