Changing the scaling factor manually in the config file does not work either, it causes all monitors to go blank as well. I observed that it is trying to set a mode "null", here is the line from the Xorg log: `NVIDIA(0): Setting mode "NULL"` I have initially noticed this after upgrading from Ubuntu 19.10 to 20.04 and my screens would all be just blank after the system has booted up. I had to delete the monitor configuration files manually via SSH to get a screen output in xorg again.
