*simply* locking the screen under Xfree

hi, i'm looking for a program which could lock the screen under Xfree but without any screensaver stuff. just a black screen. it should just ask for a password when the mouse is moved or a key is pressed. it should disallow the use of ctrl+alt+f1 or ctrl+alt+backspace. it should also be as smallest as possible and not depends on anything other than Xfree. if one of you is aware of such an app, say so!

The most simple program that comes to mind is xtrlock - it really just locks the X server until the right password is entered. The cursor changes to a lock as indicator. To unlock you just type your password - there is no password prompt or something. It doesn't blank the screen or locks it automatically - you would have to do this by hand. I use this prog on my laptop and have a shortcut there, which executes "xset dmps force off && xtrlock" to blank and lock the screen.

However there is also xautolock. But I haven't tried it yet. And xlockmore, but that one has also some simple screensaver modes I think. They are all in portage so you can just emerge them and take what you like most.

To disable the ctrl-alt-stuff you have to edit your XF86Config:

Code: Select all

Section "ServerFlags"
    # disable Ctrl-Alt-F[1-12]
    Option "DontVTSwitch"
    # disable Ctrl-Alt-Backspace
    Option "DontZap"
EndSection

xautolock is pretty straight forward and should do what you want
I use it myself
What window manager do you use. KDE has a menu option to lock the keyboard. Probably GNOME too?

thanks. i've already looked at those apps but it require scripting a bit. i was hopping for something like xscreensaver without the screensavers

i may find a solution with xautolock, or maybe i'll code something.

I think thats not possible with xfree because its handled directly by the server so that no application can intercept those keyboard events. I think its a common problem that all screen lockers have. (see for example here)
