[SOLVED] Arch KDE Wayland AMD 9070 - Buggy desktop screen? | Arch Linux Community | Page 1

I'm assuming this has something to do with drivers? Boots to sddm looks fine, can go into bios/terminal no graphical issues. Unsure if GPU works yet with drivers, not sure what to do yet. Any help appreciated!

Hi there. It should be supported with the built in amdgpu module. Just be sure you have the following packages installed and that your system is up to date (via sudo pacman -Syu):

#

sudo pacman -S mesa lib32-mesa vulkan-radeon lib32-vulkan-radeon linux-firmware

#

You should also ensure kms is enabled by editing your /etc/mkinitcpio.conf so that kms is present in the hooks array. Ex:

#

sudo nano /etc/mkinitcpio.conf

#

HOOKS=(systemd autodetect microcode modconf kms keyboard sd-vconsole block filesystems fsck)

swift prism May 6, 2025, 12:51 AM

#

stray light sudo pacman -S mesa lib32-mesa vulkan-radeon lib32-vulkan-radeon linux-firmware

Done, system is fully up to date and I tried reinstalling all of these for good measure

stray light May 6, 2025, 12:51 AM

#

Then reboot and check if the module s loaded

#

sudo lspci -v|grep amdgpu -B22

#

k, let's double check and make sure kms s in the hooks array. if it isn't add it and then sudo mkinitcpio -P and reboot

swift prism May 6, 2025, 12:53 AM

#

stray light HOOKS=(systemd autodetect microcode modconf kms keyboard sd-vconsole block files...

why sd-vconsole and block out of curiosity (sorry noob qustion), also the rest of the hooks are there

#

which DE/browser are you using btw? you can ignore most of my mkinitcpio.conf btw, there are different entries in there as I use a systemd based initramfs instead of the default busybox based one

swift prism May 6, 2025, 12:55 AM

#

KDE Plasma (Wayland), X11 works just fine for some reason

#

This isn't my setup, so how would I know if it is using busybox? I'm used to systemd myself since that's what's on my setup at home

#

lspci shows amdgpu module is loaded

stray light May 6, 2025, 12:56 AM

#

alrighty, can you get me the lspci output, just ti verify the module is indeed loaded, as well as the output of uname -a

#

that corruption happens with all apps or just specific ones?

swift prism May 6, 2025, 12:57 AM

#

uname -a shows kernal 6.14.4-arch1-2 # SMP PREEMPT_DYNAMIC

swift prism May 6, 2025, 12:57 AM

#

stray light that corruption happens with all apps or just specific ones?

The picture shown is just the desktop, I can't do much of anything

#

X11 works with no issues though

stray light May 6, 2025, 12:58 AM

#

and no other gpus or an integrated one right?

swift prism May 6, 2025, 12:58 AM

#

Integrated has been disabled in BIOS

#

Only one discrete

#

So yes!

stray light May 6, 2025, 1:01 AM

#

ah forgot to address your busybox question, you can tell by looking at the hooks. for busybox you'd have ones like base, udev, usr (you can can see the the comparrison of the hooks here https://wiki.archlinux.org/title/Mkinitcpio#Common_hooks)

#

alright, so we'll grab a copy of your boot/kernel logs and sddm logs

#

journalctl -k -b0 | curl -F 'file=@-' 0x0.st

#

journalctl -u sddm | curl -F 'file=@-' 0x0.st

#

Does this help at all? I'm honestly not sure what I'm looking for

stray light May 6, 2025, 1:15 AM

#

just looking for any errors/optimizations we could do on the bios side

#

alright, can you sudo -s dmidecode

#

sudo dmidecode |grep -v -i serial|curl -F 'file=@-' 0x0.st

#

whoops

#

sudo pacman -S dmidecode

#

1 limited by 16.0 GT/s PCIe x16 link at 0000:00:01.1 (capable of 504.112 Gb/s with 32.0 GT/s PCIe x16 link)

#

is really the main thing that sticks out, so imm hoping to get your mobo from dmidecode so we can go into the firmware and configure that picex slot to pcie vresion 5 and make sure 10-bit tagging is enabled

swift prism May 6, 2025, 1:23 AM

#

I can tell you the mobo

stray light May 6, 2025, 1:23 AM

#

usually enabling above 4g encoding and resizable bar also helps but from the logs i think that's already enabled

swift prism May 6, 2025, 1:23 AM

#

Asus tuf b650m plus wifi

#

Resizable bar is already enabled

#

Above 4g encoding?

#

Will make the above changes

#

And reboot

stray light May 6, 2025, 1:25 AM

#

yeah, have a look at https://dlcdnets.asus.com/pub/ASUS/mb/13MANUAL/PRIME_PROART_TUF_GAMING_AMD_AM5_Series_BIOS_EM_WEB_EN.pdf?model=TUF GAMING B650M-PLUS WIFI

#

i think above 4g is alreeady enabled as the bar size is above 4gb

#

but the main things i want to see are double checking above 4g anyway, resize bar so that both are enabled and i'm looking for the other 2 , pcie version 5 and 10-bit tag enable

#

okay it's under pcie link speed and looks like the first slot so PCIEX_16_1 ink mode to gen5 (but double check that's the case)

#

@swift prism laptop or desktop?

stray light May 6, 2025, 1:32 AM

#

couldn't find 10-bit tag support but pcie gen 5 implies it so you should be good with those settings

swift prism May 6, 2025, 1:42 AM

#

thick thorn <@257280086934421524> laptop or desktop?

desktop

swift prism May 6, 2025, 1:45 AM

#

stray light but the main things i want to see are double checking above 4g anyway, resize ba...

above 4g decoding is enabled

stray light May 6, 2025, 1:46 AM

#

@swift prism cool, were you able to confirm resize bar=enabled and set pcie gen 5 on the first slot?

swift prism May 6, 2025, 1:47 AM

#

PCIE mode was set to auto, forcing to version 5

#

Resize bar is enabled

stray light May 6, 2025, 1:47 AM

#

alright, let's save and boot and reget the kernel/boot logs as well as sddm logs

swift prism May 6, 2025, 1:47 AM

#

What is 10-bit tag btw? Could not find it in bios

stray light May 6, 2025, 1:48 AM

#

its basically extra settings for full speeds when sing pci gen 4

#

gen 5 basically implies you have them

swift prism May 6, 2025, 1:49 AM

#

Rebooted, still not happy

#

Lemme grab the logs

http://0x0.st/8JbA.txt

#

First one I typed wrong my b

stray light May 6, 2025, 1:58 AM

#

hmm, i don't see anything immediately obvious. mind trying with a test user just to start with a blank slate on the kde settings? sudo useradd -m -G wheel -s /bin/bash test 'sudo passwd test` then let's see if that makes a difference

#

actually...May 05 20:48:24 skrunkledorp kernel: amdgpu 0000:03:00.0: [drm] Registered 4 planes with drm panic

#

looking that up now

#

mind getting the full output of sudo lspci -v|grep amdgpu -B22|curl -F 'file=@-' 0x0.st @swift prism

swift prism May 6, 2025, 2:19 AM

#

will do, one moment

stray light May 6, 2025, 2:22 AM

#

k, i think we can ignore the panc support message as it didn't actually panic. once you get that, see if you can login to X11 and get me your monitor settings like resolution and connector name (e.g. HDMI-1 or DP-1) from kde settings @swift prism

swift prism May 6, 2025, 2:26 AM

#

just in case

#

http://0x0.st/8Jb.txt

#

x11 reset the monitor settings

#

3840x2160 16:9 60hz 200% global scale

#

On wayland everything is the same but I do not know what the scaling settings are, and I also know on wayland HDR is enabled

#

It was enabled as the drive was in a different build at some point

#

And should mention it is HDMI, not display port

#

Single monitor

stray light May 6, 2025, 2:31 AM

#

ah, yeah test with that user 'test' just to see if any kde/wayland settings are mucking with it

#

kk, per xrandr it's HDMI-1? @swift prism

#

will be back in about 10 mins or less btw

swift prism May 6, 2025, 2:33 AM

#

all good, test user works, it is the settings

#

all good no hurry, it is no emergency

#

All good, resolved!! Much appreciated, just had to reset settings on wayland

stray light May 6, 2025, 2:47 AM

#

ok glad to see that was it 🙂

#

don't forget to mark it as ''solved" @swift prism

#

...solved

#

hmm, trying to trigger the bot lol

#

... solved
