Except I use xscreensaver myself and it in no way prevents VT switch, which is what the OP was hoping to find a way to do if and only if the screen is locked. Programs that grab input still don't get to block combos that are processed by the X server before they even get to the program's input queue any more than grabbing input will block the alt- sysrq kernel-level interrupt keys. Disabling VT switch by the X server and then setting up some other way to trigger a switch that will be blocked by whatever screen locking program the OP wishes to use is the best solution I can think of. chvt would be the program to call. Whether he wants it to be a keyboard shortcut handled by his DE or some other trigger method is a matter of taste. LMP
