Lock screen problem
 

I am using centos 5

when i got preferences keyboard shortcuts

and assign ctrl l as lock screen

on pressing 'em i just get a black screen and no lock ???

can any body help me

Run Preferences — Screensaver and tick the box "Lock screen when screensaver is active".

I don't think Ctrl-l is a good idea, because it might be needed in a program. Make sure your Windows keys are properly identified as Super (use Preferences — Keyboard, choose the tab Layouts and the Layout options button) and use <Super>l.

We cant lock in root mode :P got to know now..
thanks for the help
