I've got a problem increasing my mouse sensitivty and the cursor moves pretty slow at the moment. I've tried using that sensitivity slider in the system settings but it does nothing. I found some articles here and found that I might need to lower the value of 'Device Accel Constant Deceleration', but that's already at its lowest (1.000000). I've also tried changing the polling rate described here: http://www.urbanterror.info/forums/topic/21844-howto-changing-mouse-polling-rate-on-ubuntu/ but no difference between 100Hz and 500Hz. What else can I do?

Ubuntu 12.04, MS Intellimouse Explorer 3.0

PS: xinput --list-props 8 | grep Accel shows this:

Device Accel Profile (268): 0  
Device Accel Constant Deceleration (269):   1.000000  
Device Accel Adaptive Deceleration (270):   1.000000  
Device Accel Velocity Scaling (271):    10.000000

  • I was able to set Device Accel Constant Deceleration below 1 on my system. Do you get an error when you attempt this? For example, setting it to 0.5. – TheSchwa Aug 10 '14 at 10:58
  • Yes: X Error of failed request: BadValue (integer parameter out of range for operation) Major opcode of failed request: 147 (XInputExtension) Minor opcode of failed request: 57 () Value in failed request: 0x10d Serial number of failed request: 19 Current serial number in output stream: 20 – user314246 Aug 10 '14 at 11:10
  • What command are you using to set the property? – TheSchwa Aug 10 '14 at 11:14
  • xinput --set-prop 8 269 0.5 – user314246 Aug 10 '14 at 11:17
  • Hmmm...okay, can you post the output of xinput --list-props 8 | grep Accel in your question. – TheSchwa Aug 10 '14 at 11:58
  • edited the first post – user314246 Aug 10 '14 at 12:02
  • Okay, those are the same values I have on my system. My last suggestion would be to install dconf-editor and use it to edit the motion-acceleration and motion-threshold keys in org.gnome.settings-daemon.peripherals.mouse. Those are the numbers the slider in the settings dialog is supposed to change. if that doesn't work, you'll have to wait for someone else to answer as I have no other suggestions. – TheSchwa Aug 10 '14 at 12:07

    Don't know if it will work, but you can try the "xset" command. Try a high value, like: "xset m 10 20" and see if it helps. (Note the space between the 10 and 20) – CluelessNoob Aug 10 '14 at 12:15
  • Alright, it looks like we have a success. I reseted 'motion-acceleration' and 'motion-threshold' to -1 in dconf-editor and my mouse sensitivity is way better now. Thank you for the help guys! – user314246 Aug 10 '14 at 12:37
  • Since dconf-editor worked, I posted it as an answer. When you get a chance please accept it so other users can see what worked for you :) – TheSchwa Aug 14 '14 at 04:22

Have a look at this answer: https://unix.stackexchange.com/a/177640

Basically:

  • Use xinput list to find the name of your mouse device
  • Run xinput set-prop 'Name Of Your Mouse' 'Coordinate Transformation Matrix' 3 0 0 0 3 0 0 0 1

You can change the 3s to whatever value you want (larger = increased speed). Leave all the other numbers the same. You'll need to make the command run on startup, since it only lasts for your current session.
