Title:
Adjusting the 'Pointer speed' mouse setting in Unity has no effect
Status in unity-control-center package in Ubuntu:
Confirmed
Bug description:
- What is expected to happen:
Pointer speed (mouse sensitivity) adjusts according to the slider's
position.
- What happens instead:
The setting has no effect on mouse, though the slider can be moved freely.
- How it happens:
1) Log in into a Unity session;
2) Go to System Settings > Mouse & Touchpad > Try moving the slider to
either side;
3) The new values are not applied, pointer speed is not updated.
Whenever the slider's position is moved, the "speed" key in
"org.gnome.desktop.peripherals.mouse" gsettings schema updates
accordingly, however the "libinput Accel Speed (290)" property does
not. It stays at 0. Manually setting a value to this property (xinput
--set-prop device property value) has an immediate effect.
This setting works as expected during a GNOME session. Both the
"speed" key and the "Accel Speed" property update as the slider is
adjusted.
