I went to "System Settings", "keyboard", "shortcuts", "custom shortcuts", I added a custom shortcut and called it "task manager" in the "command line:" I typed "gnome-system-monitor", and I gave it the command, "ctrl+alt+del", I apply that and close it. Then I try it and get NOTHING...... why??

then click on the space where "Disabled" is writen and press the kay combination(other than alt+cltr+del.it is assigned to log out) for e.g as seen in picture, i had assigned alt+cltr+menu(the right-click menu button on the right of space bar)
if you still want to assign alt+cltr+del as the key binding,change the one for log out in the "system" option there and then assign it to this.
