Hi,
I'm running Ubuntu 20.04.1 LTS with Gnome 3.36.3 on a Novatech laptop with Mesa Intel® HD Graphics 630 (KBL GT2) onboard and Nvidia GeForce GTX 1070.
A couple of days ago it crashed back to the graphical login screen after I logged in. I switched to a virtual terminal to try and figure out what was going on. I installed nvidia-driver-450 and rebooted. I alternated between installing the drivers in Gnome and from the CLI with apt-get. I purged nvidia* drivers and reinstalled and rebooted.
I'm now at a point where I can use prime-select to set the system to either intel or nvidia. If I select nvidia it will display correctly on an external monitor but not on the built in monitor. The external one only appears in settings/display. When I select intel and reboot it will display exclusively on the built in laptop screen and not the external monitor. It's also limited to 960*540 resolution. I'm thinking reinstalling the Intel drivers might help but I'd still have a configuration issue. I can't hotkey between screens and only the currently selected one is available via the settings GUI.
This configuration previously displayed on both internal and external screens without issue. I used to see both displays available in settings where now I only see whichever is set by prime-select.
