I think I may be having a related issue. Lenovo P1 Gen 2 Ubuntu 20.04 I am trying to connect 2 external monitors both connected via USB-C
All was well for the first 2 hours. Then I unplugged my laptop worked off of battery for about an hour. Tried to plug back into the monitors and thats when the problem showed up. Now I can get 1 external monitor to show up, But when I try to connect both external monitors, both are just black (both are recognized both by ubuntu (under displays) and by nvidia-settings.
