For gaming precision on PC, I have disabled mouse acceleration. The mouse speed works as I wanted to, however the touchpad is just too slow.
Is there a way to have separate cursor speed for mouse and trackpad? I prefer no acceleration at all
Nope, not possible in the current version of Ubuntu. You might, however, want to take a look at / contribute to this thread on Ubuntu Brainstorm: http://brainstorm.ubuntu.com/idea/6030
