MOUSESTATE on Linux doesn't seem to be working

[MrTAToad]

MouseState on Linux seems to be only returning one of the four following values for the mouse position :

0,0
0,479
639,0
and
639,479

[Kitty Hello]

systempointer true or false?

[MrTAToad]

FALSE

I have a feeling its VirtualBox being a problem.

Yes, its certainly that...
