I have a laptop with i7-12700H and RTX 2050, with only a single VGA controller connected with iGPU. lspci | grep -iE "vga|3d" shows:
00:02.0 VGA compatible controller: Intel Corporation Alder Lake-P Integrated Graphics Controller (rev 0c)
01:00.0 3D controller: NVIDIA Corporation GA107M [GeForce RTX 2050] (rev a1)
I have an HDMI port on the side of my laptop, which works well while using windows and booting Linux (for example, under grub). However, once i915 driver is loaded, the external screen become black and complains "no signal". This is my kernel log: https://fars.ee/gQTL Could anyone figure out where is the problem?
