If I plugin the second screen (external monitor) using HDMI before logging into
my session, the second screen is blank, although it receives a signal.
In order to get the image, I have to either deactivate and reactivate it from
Display Settings, or move any window to it.
This happens using the following config:
Laptop: Lenovo Legion 7 16ACHg6
CPU: AMD Ryzen 9 5900 HX APU
RAM: 32 GB DDR4-3200
GPU: iGPU AMD Vega 8 + dGPU NVIDIA GeForce 3080 Mobile GPU (Max-P)
Main laptop screen is powered by iGPU whereas external screen is powered by dGPU
