Is there a way to "lock" the screen in Fedora and still see everything which is happening on the screen, as if it were unlocked? That is, if you try and do something (i.e. move mouse, use keyboard) the console will say "no, enter password." Ideas?
Sounds like a transparent xscreensaver module would do the trick. I haven't looked at xscreensaver code in a while, but I don't think it would be too difficult, and I can definately see applications for something like this.
