(I have the same problem as this guy, exact same issue.)
I have an hpec2075 ax laptop with AMD R5 APU and RTX 3050 eGPU.
My issue and problem is exact same except his got solved with optimus setting where as I don’t have optimus.
Preformatted textSame as him when I remove the /etc/X11/xorg.conf , that I generated with nvidia-xconfig, then my external display starts to work that is connected with the HDMI, else if I delete those file, then only my intenal laptop display would work.
Here, as you can see my inix -G output,
Here, my xorg.conf :
