In the Mouse preferences dialog I've set the acceleration to max and the sensitivity to min and the mouse pointer is not exactly sluggish, but I'd like to make it even faster. Is it possible to be done by setting some value in the procfs or something?

The xset command allows you to change quite a few aspects of your desktop, including mouse acceleration.

xset m 2 1

The first number is the acceleration, the second is threshold. So, in the example I provided, the mouse will go 2X as fast once it's traveled 1px across the screen. Zero has some special connotations, so I'd stick with 1.

I wouldn't think you would need to set the acceleration too high to get what you're looking for.

This effect will disappear once you reboot/restart. If it works for you, the command can be added to your "Startup Applications" to be applied automatically.

Good luck!

Set it to 16 1 and is working splendidly now! Thanks! – Albus Dumbledore Feb 24 '11 at 13:10
Wow, you weren't kidding when you said you wanted it fast! :) – Windigo Feb 24 '11 at 22:12
I needed to slow my mouse down, so I used xset m 6/5 0. @AlbusDumbledore you're a cyborg. I could hardly click on my terminal window with that setting! – lgarzo May 24 '12 at 14:30
Haha. Well, it depends on the mouse. With nice mice I'd go lower, like 12-13. – Albus Dumbledore May 25 '12 at 15:04

There is a number after which the speed isn't increasing.

After this number I've set it to 30, and 200 and the speed is the same. It's still slow, but it is faster than it was before.

I guess it depends on the mouses DPI. The Steelseries Sensei has the most DPI: 16000 DPI. A higher DPI is always better once you know it, but it isn't really that fast when you have one or more 4k monitors.
