So I have the proprietary drivers in use. Using xorg, the screen resolution is too small. Using wayland, it is normal. GDM did not show wayland/xorg options, so I installed both lightdm and sddm before the whole black screen debacle and am not sure which loads the login now. Both have some messed up gnome things going on: no dock, no window minimize buttons, missing panel system indicators, etc. And the second monitor fails to show a screen on either.
Should I create a new topic for that or is there more that can be done here?
