Xorg - Integrated graphics doesn't detect HDMI output

fan87 · 2023-02-08 22:38:47

When I try to use integrated graphics, it doesn't detect HDMI anymore.
I'm using laptop with both Integrated graphics (intel) and NVIDIA card
if I use NVIDIA in xorg config, the HDMI output works, and games become laggy with

prime-run

(In this case: minecraft)
Here are some (hopefully) useful information:

ls /usr/share/X11/xorg.conf.d

.rw-r--r--   92 root 24 Feb  2022 10-amdgpu.conf

ls /etc/X11/xorg.conf/d

My xorg.conf is empty,

Don't use optimus-manager, https://wiki.archlinux.org/title/PRIME#Reverse_PRIME
Also see the note on the top on what happens if you only use the external display.

prime-run

There's absolutely no point to use prime-run if you're running on the nvidia chip

Without prime-run, it won't run with NVIDIA card I guess?
Otherwise everything will be using NVIDIA card, which is gonna make the game slow

If you configure the X11 server to run on the nvidia chip, everything runs on the nvidia chip by default. Hence there's no point in using prime-run as prime-run will seek to run the process on the nvidia chip… where it's running anyway.

Check the link I posted before and please post your Xorg log, https://wiki.archlinux.org/title/Xorg#General
