Modify Ctrl-Alt-Del Behavior in Linux

I hate the Ctrl-Alt-Del combination, maybe because it reminds me of the unpleasant days when I used other operating systems. If you want to modify it, then here is how to do this:

In Ubuntu

Open the file /etc/event.d/control-alt-delete  (You need supper user privileges)

You should see a line similar to this:

exec /sbin/shutdown -r now “Control-Alt-Delete pressed”

Which binds ctrl-alt-del to rebooting your computer. Change it to execute any other program you want. Of course you can disable it completely by commenting the whole file.

Other Distros (via Tips4Linux)

In other distros, open /etc/inittab.

You should see something like this:

ca:12345:ctrlaltdel:/sbin/shutdown -t1 -a -r now

To disable ctrl-alt-del, just comment this line. To bind it with other program, just replace “/sbin/shutdown -t1 -a -r now” with the program you want to execute.

Enjoy!
