hi guys
So while trying to solve Logitech TouchPad T650 intermittent freezing issue, I installed Solaar ( https://pwr.github.io/Solaar/ ) via Synaptic. During the installation, it asked me to select between GDM3 and LightDM and I accidentally selected GDM3.
So now I'm stuck with GDM3 (to me it feels like being blinded). So far I've tried the following few times and rebooted few times but to no avail.
sudo dpkg-reconfigure lightdm
And on top of this TouchPad has kinda stopped working... while cursor moves, left/right click is not working. It's a desktop PC running Ubuntu Mate 18.10 64bit.
I like to get back to LightDM and remove Solaar, GDM3, etc.. completely. Thanks alot in advance.
Edit: I did figure out that, reconfigure lightdm was working but the system was booting in to Wayland desktop environment. I logged out and logged back into Mate, and it's working just fine
Now is safe to remove Wayland? How could I do that please.
