gdm3 boots to blank screen when using Nvidia (on a desktop with an unused Intel GPU)
gdm3 boots to blank screen when using Nvidia (on a desktop with an unused Intel GPU).
The reason seems to be that mutter supports the headless Intel GPU with the native backend and so never uses the Nvidia GPU that the monitor is connected to. The Nvidia GPU only works with Xorg though, because nvidia-drm.modeset=0
. In this case we need gdm3 to use Xorg by default.
