Can anyone explain to me why Ubuntu doesn’t like kvm switches that use a scroll lock key combination to switch from one workstation to another?  For that matter can anyone explain to me why Ubuntu / gnome doesn’t like scroll lock? Not sure if this is a gnome specific issue or an Ubuntu issue but someone should have fixed this by now.  There are forums mentioning this from back in 2004.

Anyway my quick workaround for kvm switches which don’t support Num lock X 2 is to simulate it from the command line.

xset led on
xset led off

The above will simulate a scroll lock on and off action, repeat until you are switched

Alternatively you can switch terminals (correct terminology?) and use scroll lock normally.

Control + Alt + F1 will take you to the console, then use scroll lock X2 to switch.  When back do a Control + Alt + F7 to return to the gnome console.
