I am one of a long list of Ubuntu users who have complained of the cursor jumping to elsewhere on the screen or to another screen while typing.
I'm using the keyboard on the Serval Pro.
I have tried the included touchfreeze utility. Unfortunately, I could find no documentation for the choices in this utility. After having tried various choices, I finally gave up using this utility because no setting seemed to stop the jumping cursor problem.
I then read various suggestions on how to fix this problem in lucid. Nothing that I tried fixed the problem.
Just typing this note was agony.
Do you have a suggestion that works?
