I'm sure everyone has hit these three buttons before. So annoying! Here is how to disable them:
- Open xorg.conf for editing
Code:sudo gedit /etc/X11/xorg.conf
- Add these 3 lines to the end:Code:Section "Serverflags" Option "DontZap" "yes" EndSection
- Save the file and close gedit
Now all you have to do is run 'sudo invoke-rc.d gdm restart', hit ctrl-alt-backspace (last time it will work), or log out and ctrl-alt-backscape will be dead!
