Lock X screen and lock ctrl/alt keys
 
Hello guys!

I use slock for IceWM but slock doesn't prevent a person from going to VC or hit Ctrl+Alt+Backspace to terminate X. Is there any program for locking up X screen which also locks up "Ctrl" and "Alt" keys so you can't go to VC?

I would think it might be a keyboard mapping, I could be wrong but I *think* I have seen something to this effect before.

You can control Xserver behavior by /etc/X11/xorg.conf file, you need to add options:
Code:

Section "ServerFlags"
  Option "DontVTSwitch" "True"
  Option "DontZap" "True"
EndSection

And probably add "Screeen" and "Device" sections if you have no xorg.conf already.

eSelix, these options disable those keys permanently, right? I need to disable them only when slock is running.
rhbegin, I use setxkbmap to set Ctrl+Alt+Backspace.
