gray desktop or login loop

[Diego Pedrosa]

I'm using Ubuntu 20.04 (all upgrades)

I was using MATE until I decided to go back to budgie since MATE started hogging system resources.
after removing MATE and trying to login with budgie I only get a gray screen.
I reinstalled lightdm, budgie desktop, nvidia drivers, etc.
the only desktop environment that I can use is GNOME(Metacity)
