OSK - OnScreen Keyboard.
Well... onboard is installed, but I can't open it, so I consider is broken or something.
I tried Cellwriter, but it's only for i368 or whatever, but not for amd64.
Right now ubuntu packages is down, so i'll try synaptic with
1.) GOK. - However this was too complicated for me.
2.) Matchbox OSK
... I updated to Gutsy, I'll check this out later...
