Can no longer see dedicated GPU, Works on live Garuda usb. Relevant logs attached

Issues & Assistance
1

Despite it fully functioning before, running a game, nvtop, lshw or any similar command, my dedicated graphics card does not appear anywhere other than a few non error lines in dmesg.

I do not know exactly when it stopped working or what triggered it. It may have happened any time over the span of ~2 weeks when I was attempting to get some software working that required rocm, I’ll attach my relevant shell history or other log files if it would help.

Here’s some of what I’ve tried so far:

My integrated GPU and its drivers are working properly, tested by running glxgears and glxinfo.

The integrated 680M with 512MB of memory is seen here. The dedicated 7600S which has ~8GB of memory is not.

As I was having some problems with a few other kernels I had installed (linux-tkg-bmq, linux-zen etc.), I swapped to bootctl/dracut and fixed the problems with those kernels, swapping kernels did not change anything.

I tried booting into a live USB of Garuda, nvtop showed both my dedicated and integrated GPU.

I tried diffing “pacman -Qq”'s output between the live system and mine.
Here’s a list of all packages that exist on the live USB and do not exist on my system, none seem relevant.

comm -23 pacman-live-usb.txt pacman.txt
arch-install-scripts
calamares-branding-garuda
calamares-garuda
garuda-boot-repair
garuda-dracut-support
garuda-live-base
garuda-live-skel
garuda-live-systemd
garuda-tools-base-git
grub-garuda
grub-theme-garuda-live
grub-theme-garuda-live-common

I tried re-installing the mesa OpenGL drivers, which changed nothing.

I tried booting to both plasma X11 and wayland, the dedicated GPU did not work on either.

I tried uninstalling the rocm drivers which were previously working fine.

sudo pacman -Rc opencl-amd
sudo pacman -Rc rocm-hip-runtime
sudo pacman -Rc rocm-core hip-runtime-amd

I tried swapping to the aur/vulkan-amdgpu-pro and aur/lib32-vulkan-amdgpu-pro drivers, which did not work.

I tried enabling and disabling the apparmor kernel parameters, rebooting changed nothing.

I also tried searching the internet, as my google-fu wasn’t enough, I tried a few language models, none helped.

I’ve confirmed amdgpu drivers are working

Try running sudo pacman -S mesa lib32-mesa xf86-video-amdgpu vulkan-radeon lib32-vulkan-radeon libva-mesa-driver lib32-libva-mesa-driver linux-lts linux-lts-headers and reboot. Then paste the output of uname -r

Also make sure amdgpu is NOT blacklisted inside any .conf file in the /etc/modeprobe.d directory.

Thank you for your suggestions.

Also make sure amdgpu is NOT blacklisted inside any .conf file in the /etc/modeprobe.d directory.

I believe I’ve already verified that amdgpu is loaded, What will this tell you?

cat /etc/modprobe.d/*
options v4l2loopback_dc width=640 height=480

lsmod still shows amdgpu

 there is nothing to do

I assume you want me to reboot into the lts kernel? I’ll reinstall everything anyway and try that now.

I’ve rebooted into lts:

uname -r
6.6.31-1-lts

sudo ls -l /boot/efi/EFI/Linux/
[sudo] password for user:                  
total 214676
-rwxr-xr-x 1 root root 219825152 May 21 13:27 linux-6.6.31-1-lts-9aa8ed400806402aa5d663b734695747-rolling.efi

there are no changes, nvtop still shown only my integrated card, as does inxi

inxi -G

I do not believe the problem is missing drivers, as I tried booting into a live system, which showed both cards.
I then tried diffing the installed packages on this system and the live system.

These were the only different packages:

comm -23 pacman-live-usb.txt pacman.txt
arch-install-scripts
calamares-branding-garuda
calamares-garuda
garuda-boot-repair
garuda-dracut-support
garuda-live-base
garuda-live-skel
garuda-live-systemd
garuda-tools-base-git
grub-garuda
grub-theme-garuda-live
grub-theme-garuda-live-common

none of these seemed relevant to my issue.

make a new .conf file named amdgpu.conf in the /etc/modprobe.d and add in the following lines:

options amdgpu.cik_support=1
options amdgpu.si_support=1

Reboot.

See if this works

I’ve rebooted with those options.

I couldn’t find a simple way to see the options of loaded modules so I used an llm to write a script.

#!/bin/bash

echo "Module\tOption"
for mod in $(lsmod | awk '{print $1}'); do
    dir="/sys/module/$mod/parameters/"
    if [ -d "$dir" ]; then
        for opt in $(ls $dir); do
            echo "$mod $opt"
        done
    fi
done

both options appear.

amdgpu cik_support
amdgpu si_support

Nothing has changed, nvtop and inxi -G have the same output.

What are the cik_support and si_support drivers?
I tried to find the documentation but it didn’t explain much.

Sorry, idk a lot about amd and personally have an Intel igpu. Please excuse my inability to help you.

9

Thank you for your time. I appreciate the suggestions!

10

Have you checked whether the dGPU is activated in the BIOS?

11

No, I haven’t, but as it worked on a live system, I do not believe that can be the problem.

12

Solved.

For whatever reason my supergfxctl config reset.
As I set this up a few years ago I didn’t think to check.

diagnosed with

sudo supergfxctl -g
Integrated

setting the default to Hybrid fixed my problem.

Mode can be set via kernel cmdline with `supergfxd.mode=`. Capitalisation does not matter.
