Well, sorry if i don’t follow along 100% the discussion you linked on arch forums. Is your duty to trim the information.
You can place the 10-nvidia-drm-outputclass.conf as suggested in the wiki or as whoever mentioned it on that arch forum. Both places are valid.
You can simply create a blank file with sudo touch /etc/X11/xorg.conf.d/10-nvidia-drm-outputclass.conf
or sudo touch /usr/share/X11/xorg.conf.d/10-nvidia-drm-outputclass.conf
then edit it and add as per wiki the
Or do it from another file you copy and then replace the lines … is up to you, just don’t make typos in it.
Reboot and test your dual screen.
If you have issues with Screen tearing with nVidia driver, as per that wiki, then you create the other file and add those lines to it and reboot, test …
By the way, what did you do when you first installed the system? Did you took notes about that? Or there was nothing special what you did, and worked by default?
Listen, it is the first time I have heard about this configuration.
My system is up with Manjaro since more than 2 years.
It was working with two monitors since last week.
Do we need to make this configuration for G5 after the installation? I do not remember I have done, but it was more than two years back…
What changed? If you just switched to the 5.19.1 kernel, have you also tried to boot, without touching the configurations, into another kernel? Maybe 5.15 …
Your system is a Laptop with dual GPU
Is the first time to see such system that does not make use of video-hybrid-intel-nvidia-prime driver, so after reading that wiki, to me it appeared that to be a special case and that is what it needs to be used, and based on that information, those files are a requirement.
you have probably some leftovers from the eol 5.17 kernel, so check with:
ls /etc/mkinitcpio.d/*.preset
sudo ls /boot/initramfs-*
sudo ls /boot/vmlinuz-*
sudo ls /usr/lib/modules/*
try switching to the 5.15 lts kernel and see if it helped
check if you can switch your graphics in bios
and until you installed video-linux you were running primary on your nvidia
with bios i meant, some bioses have a option to switch between gpus, and to try it out if you have it
i noticed you have som amd conf there, but you are running intel+nvidia, provide output from: find /etc/X11/ -name "*.conf"
so you have installed optimus… did you had it installed when the screens were working, or you installed it afterwards?
post output from: pacman -Qs optimus
