Here's a small thing that I find VERY frustrating under Linux -

The NUM lock default is off - so each time when it is off and I go to use the keypad (which I do all the time) it puts my cursor off in to never never land

Is there a way to set the caps lock default to on ? (I thought it may have been in BIOS - I am sure it was on an old machine of mine - but can't find it on this one)
