Whenever I am at work, I would like to lock the computer so my desktop isn't accessible to others. In windows it's trivial, press the Windows+L key. Is there something similar available in Linux, particularly Fedora.

In many window managers, screen lock is available by mouse click from a drop-down context menu in the dock. – ire_and_curses Jan 18 '13 at 23:12
Which Fedora release and desktop? The answer depends. – mattdm Jan 19 '13 at 18:55

This varies depending on desktop environment. In Gnome and KDE, you can use ctrl+alt+L by default.

On my system, it brings up the option to "Shutdown", "Logout", "Hibernate" etc. However, I don't see any option that matches the lock. – Shamim Hafiz Jan 18 '13 at 22:37
@ShamimHafiz - That's what Ctrl+Alt+delete does on my gnome system... – jordanm Jan 18 '13 at 22:39
@ShamimHafiz Does ctrl+L work? – jordanm Jan 18 '13 at 22:45
CTRL+L also does not work. In fact, it doesn't seem to do anything. – Shamim Hafiz Jan 18 '13 at 22:54
@ShamimHafiz - This link may be helpful for Gnome 3: askubuntu.com/a/122776 – jordanm Jan 18 '13 at 23:03
