I have installed a screensaver (slock) so that when I click on the screenlock icon in the lower right-hand corner of the desktop, the desktop locks out until I enter my password.
I would like to take this one step further and have the desktop lock out automatically after a certain amount of time (e.g., 10 minutes). I haven't been able to find how to configure this. I can use "xset s 600" so that the screen goes blank after 10 minutes, but this is different from locking out, since I don't need to enter my password to go back to the desktop.
Thanks for any advice!
