http://crunchbang.org – I am currently trying $ xinput --set-prop 'Logitech USB Receiver' 'Device Accel Constant Deceleration' 0It doesn't work because I have two devices with the same name, they are both pointer as well so doing pointer:Logitech USB Receiver is also out of the question. this is what i get when i put in xinput listmichael@crunchbang:~$ xinput list ⎡ Virtual core pointer id=2 [master pointer (3)] ⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)] ⎜ ↳ PS/2 Generic Mouse id=14 [slave pointer (2)] ⎜ ↳ Logitech USB Receiver id=11 [slave pointer (2)] ⎜ ↳ Logi (HowTos)
