I just updated to Ubuntu 20.04.1 LTS and the mouse settings obviously re-set to the defaults where the left button is the primary. I mouse left handed and want the right button to be the primary. I open Settings>Mouse & Touchpad, select Right as Primary Button and all is good. When I KVM over to another system and come back to Ubuntu, the default mouse setting are back.
Please help me get this setting to stick.
gsettings set org.gnome.desktop.peripherals.mouse left-handed true
and see if that sticks that way. – Terrance Nov 18 '20 at 16:23
