Is there way to increase the mouse speed in KDE4? I don't want any pointer acceleration, it's just the mouse speed that I want to change.
Edit: Unfortunately, editing the xorg.conf is not an option for me, because I want the users to be able to configure the mouse speed themselves and it is company policy do deny users permission to change the xorg.conf.
KDE has not built this into its control center yet, but you can use xinput from the command line. First, run xinput list to find the device number of your mouse:
$ xinput list
⎡ Virtual core pointer id=2 [master pointer (3)]
⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)]
⎜ ↳ SynPS/2 Synaptics TouchPad id=10 [slave pointer (2)]
⎣ Virtual core keyboard id=3 [master keyboard (2)]
↳ Virtual core XTEST keyboard id=5 [slave keyboard (3)]
↳ AT Translated Set 2 keyboard id=9 [slave keyboard (3)]
On my laptop, the device id I want is 10 (SynPS/2 Synaptics TouchPad). On your system, you will have to decide which device is the correct one. Next, run xinput list-props <your device id> to see the current settings for that device:
$ xinput list-props 10
Device 'SynPS/2 Synaptics TouchPad':
Device Enabled (144): 1
Device Accel Profile (266): 1
Device Accel Constant Deceleration (267): 2.500000
Device Accel Adaptive Deceleration (268): 1.000000
Device Accel Velocity Scaling (269): 12.500000
[ many more settings omitted ]
The property you are interested in is "Device Accel Constant Deceleration (267)". To slow your mouse down, the value must be increased by running xinput set-prop <your device id> <property id> <value>:
$ xinput set-prop 10 267 5.0
In this example, the value is increased from 2.5 to 5.0 and the mouse moves at half-speed.
