Describe the bug
NVIDIA driver has issues with detecting HDMI connection on eGPU on Thunderbolt 3. Sometimes it works, sometimes it doesn't.
The issue happens sometimes with modeset=1, and always with modeset=0. To make it work I have to make sure eGPU is connected during boot and modeset=1 is set, but if eGPU is not connected during boot or reconnects - it's not possible to enable HDMI.
If I unload nvidia driver and load nouveau kernel module - it detects HDMI without any issues immediately on the same machine without reboot, but that driver has many other issues.
To Reproduce
easy way is to set modeset=0 , harder way to find a reason why it sometimes detects and sometimes not with modeset=1, but it's definitely not stable
