Public bug reported:
1) Ubuntu Bionic Beaver (development branch), Release: 18.04
Fresh installation from Xubuntu 18.04 beta1 ISO, and "apt updated"
daily.
2) package: xfce4-settings 4.12.3-0ubuntu1
3) What to expected to happen?
Running the application "xfce4-mouse-settings" from the above package, changing
the sliders "acceleration" and "sensitivity" should change the mouse speed.
4) What happened instead?
The sliders have no effect, i.e. you change the mouse acceleration and
sensitivity sliders but both don't haven't any effect on the mouse.
Tested on several different machines with different mice. With Xubuntu 16.04
the xfce4-mouse-settings still work fine on the same machines.
While "xfce4-mouse-settings" doesn't work in Xubuntu 18.04 on these
machines, chaneing the mouse speed with GNOME's "gnome-control-center"
works fine on the same installation.
Maybe the bug is related to the new libinput system introduced in Ubuntu 18.04?
The terminal command:
mouse [accel] [threshold] [mouse default]
doesn't change the mouse speed in Xubuntu 18.04.
However the terminal command:;
xinput
does work in Xubuntu 18.04, but it only knows one parameter instead of the two
used by "xfce4-mouse-settings".
For example the following works for me:
xinput set-prop "PixArt USB Optical Mouse" "libinput Accel Speed" -0.6
