In the end I upgraded to Xubuntu 18.10, and I've now got things how I want. However, the GUI still doesn't work properly: it has acceleration, which works, but no sensitivity. In that sense the upgrade was a waste of time.
However I managed to get my trackball working by using xinput. I don't know whether these options would work in 18.04, because I've only just found the one that makes the difference on the following page: https://unix.stackexchange.com/questions/358016/increase-mouse-speed- xinput Here's what I did to make my trackball responsive. (You can run "xinput list" to find the name of your pointing device - mine is a 'Logitech USB Trackball'.) xinput set-prop 'Logitech USB Trackball' 'libinput Accel Speed' 1.0 xinput set-prop 'Logitech USB Trackball' 'libinput Accel Profile Enabled' 1 0 xinput set-prop 'Logitech USB Trackball' 'Coordinate Transformation Matrix' 6 0 0 0 6 0 0 0 2 The last line is what I was missing before when trying things on 18.04. The 3 non-zero arguments are horizontal speed (higher is faster), vertical speed (higher is faster), and sensitivity (lower is more sensitive - maybe pixel distance before acceleration?). The default values are 1 1 1, but 6 6 2 works better for me. Don't change the zero arguments otherwise crazy things can happen. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1758023 Title: Mouse acceleration not configurable in Xubuntu 18.04 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xfce4-settings/+bug/1758023/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
