I have a Razer Deathadder. It's a nice gaming mouse. In Ubuntu its polling rates are through the roof, though, and the mouse is pretty much unusable even with the mouse sensitivity and acceleration settings at their lowest.
Here's how I regained my sanity and mouse slowness. This fix should work for any mouse (tested with many different mouse brands, including Logitech.)
Fix for Ubuntu 10.04-14.04 and Fedora 12-20
- Open a terminal
- Run the command:
xinput --list --short
⎡ Virtual core pointer id=2 [master pointer (3)] ⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)] ⎜ ↳ Razer USA, Ltd DeathAdder Mouse id=6 [slave pointer (2)] ⎜ ↳ Razer USA, Ltd DeathAdder Mouse id=7 [slave pointer (2)] ⎜ ↳ Razer DeathAdder id=11 [slave pointer (2)] ⎜ ↳ Macintosh mouse button emulation id=12 [slave pointer (2)] ⎣ Virtual core keyboard id=3 [master keyboard (2)] ↳ Virtual core XTEST keyboard id=5 [slave keyboard (3)] ↳ Power Button id=8 [slave keyboard (3)] ↳ Power Button id=9 [slave keyboard (3)] ↳ Dell Dell USB Keyboard id=10 [slave keyboard (3)]
- Note the name of your device. (In my case, manipulating 'Razer DeathAdder' worked.)
- Set the constant deceleration for the device:
xinput --set-prop "Razer DeathAdder" "Device Accel Constant Deceleration" 5
That's it. You might have to play around with the value, but 5 slowed down my mouse sufficiently.
- To see the current settings for the device:
xinput --list-props "Razer DeathAdder"
- To turn off mouse acceleration:
xinput --set-prop "Razer DeathAdder" "Device Accel Velocity Scaling" 1
To perform the tuning automatically, I simply created a file containing the script below, ran
chmod +x on it and added it to GNOME's Startup Applications —
gnome-session-properties, or System -> Preferences -> Startup Applications, or the gear in the upper-right corner -> Startup Applications in Ubuntu's Unity.
#!/bin/sh xinput --set-prop "Razer DeathAdder" "Device Accel Constant Deceleration" 5 xinput --set-prop "Razer DeathAdder" "Device Accel Velocity Scaling" 1

Fix for distributions using HAL (including Ubuntu 9.10)
- Open a terminal
- Run the command:
- In the output, locate the mouse's hex format vendor and product ID's as highlighted below:

Note that there can be more than one section containing the name of your mouse or its manufacturer — if you can't find the product and vendor ID, look further down.
- Edit the HAL policy file for input devices:
sudo nano -w /etc/hal/fdi/policy/10-x11-input.fdi
- Insert the following text:
- Hit Ctrl + X, then Y to save the file and exit
- Restart hald:
sudo service hald restart
- Restart X.Org (log out or reboot your computer)
<?xml version="1.0" encoding="UTF-8"?> <deviceinfo version="0.2"> <device> <match key="@input.originating_device:usb.vendor_id" int="0x1532"> <match key="@input.originating_device:usb.product_id" int="0x7"> <merge key="input.x11_options.ConstantDeceleration" type="string">5</merge> </match> </match> </device> </deviceinfo>
That's it! The "ConstantDeceleration" setting in
/etc/hal/fdi/policy/10-x11-input.fdi is what does the trick. When set to a value of 5, the sensitivity will essentially be divided by 5. Oh, sweet sanity.
