I never used this machine under another OS and am not sure how responsive it is there. It’s just too slow, when it crosses the screen diagonal in more than a second at full force. How do I find out where the kernel bits that used to be there went? I guess that is where the real resolution should be set?

In the others I get odd »staircase« motion (see the animated gif under [1]). It has completely different sensorimotor contingencies now, so I have to relearn to control the cursor using this. Is there a difference between 30/10 and 3/1? Why is this a fraction and not a float? How does it interact with the acceleration setting that Gnome exposes in the Mouse Properties? Should I reset that one to zero?
