Repair Ubuntu Grapical Startup

[mahesh]

So I was messing around with trying to get VNC working and when I installed lightdm all hell broke loose and now Ubuntu won't start properly when rebooted. I removed lightdm but my gnome session won't start unless I boot into recovery and startx. Not sure if that's even running gnome because my second monitor no longer displays. Any help with repairing my log in session? Thank you

I'm running Ubuntu 20.04.3 64-bit
Gnome Version is 3.36.8
