Can't use my graphic card [AMDGPU]

Neutrynos · 2021-11-30 22:13:55

Hello,

I have issues to put my new graphic card in use. It's a AMD RX 6600. I also have a AMD 4650G CPU.
The problem is that when I plug a HDMI on the grpahic card, there is no signal.
I ensured that the amdgpu is loaded by checking lsmod.

Here is what I can see from lspci :

0f:00.0 VGA compatible controller [0300]: Advanced Micro Devices, Inc. [AMD/ATI] Navi 23 [Radeon RX 6600/6600 XT/6600M] [1002:73ff] (rev c7)
Subsystem: Gigabyte Technology Co., Ltd Device [1458:2334]
11:00.0 VGA compatible controller [0300]: Advanced Micro Devices, Inc. [AMD/ATI] Renoir [1002:1636] (rev d9)
Subsystem: Advanced Micro Devices, Inc. [AMD/ATI] Renoir [1002:1636]
Kernel driver in use: amdgpu
Kernel modules: amdgpu

So I guess that amdpgu was associated to my CPU instead of my GPU.

I also configured Xorg as in the wiki section here : https://wiki.archlinux.org/title/AMDGPU … figuration

Section "Device"
Identifier "AMD"
Driver "amdgpu"
EndSection

It's been more than a week that I'm trying to make it work, but I'm kind of lost, I don't know where to look.
Of course I'd like to enable my second screen, but more than that, I'd like to understand a bit more how all of this work. I think I have understood the kernel part, but once the drivers are loaded, I don't really understand how it's put into use.

If it's useful, here is what I found in dmesg for amdgpu :

Should I consider a different Xorg configuration given that I got 2 graphic units in my computer ?
Does anyone have a clue of what I might want to look at ? Thanks in advance

Please post the xorg.log from with and without the use of that Xorg config and the full ungrepped dmesg output. Are there any other displays than the HDMI one attached to the system?

Neutrynos · 2021-11-30 23:21:52

I have one screen plugged by HDMI on the motherboard (my working screen) and another one plugged by HDMI on the GC (the unworking one).

Have you tried with the current linux package?

Neutrynos · 2021-11-30 23:54:04

That's another issue I have. When I update linux I have problems when booting, because it fails to load kernel modules, so I downgrade each time. (My boot setup is crappy, I don't manage to find the right configuration for grub + efi on this computer, I have another one with almost the same configuration and no problems, but on this one there is always something wrong. Since I can boot I haven't search too much yet, but I think I should search a bit more before posting something here)

Which was first added to 5.11-rc1 and was not back ported to 5.9.Y as it was a new feature.

You're either booting from the root partition or the /boot partition isn't mounted during updates.

Haha, unfortunately that's pretty much that. I can't escape this anymore. I know my /boot partition is mounted so it must be the other thing.
