Just did a fresh install of Ubuntu Budgie 18.04 and my right click is not working at all with my touch pad, tried it with both a live session and a full install and on both cases my right click is useless, nothing on budgie settings or system settings helped, my right click does work with a mouse and have been able to use it with my touch pad on a live session of Kubuntu 18.04 as well as Ubuntu 16.04
Hopefully there is solution or I might have to use another flavor since the use of the touch pad is essential for me.
