Private bug reported: In an one-off situation, the Gnome was not activating the rest of the displays.
Trying to replicate > The most straightforward way to reset the graphics card driver on Windows is by using the keyboard shortcut. For that, use the key combination Win + Ctrl + Shift + B. I did: $ echo 1 | sudo tee /sys/class/drm/card0/device/reset $ # /sys/devices/pci0000:00/0000:00:02.0/reset Which resulted in the screen(s) going completely blank. Ctrl+Alt+Fx didn't work.
