Locking your screen on Debian

A small post about protecting your desktop.

If you are using Gnome, you should be able to lock the screen with Ctr-ALt-Del.

If you prefere ligthweight programs, I tried slock but did not really like it as it is not clear when the deskop is locked. i3Lock is similar but is an improved version. Finally, xtrlock is the one I use currently.
