Tumbleweed / KDE Plasma 6.6 / Stutter every 10 seconds

English Install/Boot/Login
1

Hi, I made a thread about this before, but it closed because it was a while ago.

Basically I have a 7950X3D / RTX4090 desktop running OpenSUSE Tumbleweed with KDE Plasma.

(I have 3 monitors connected to the 4090, and 1 connected to the iGPU, but this problem reproduces with it disconnected and the iGPU disabled in UEFI).

When I am using it on an HDMI connected TV, sometimes it will stutter every 10 seconds, switching to the TTY for a while sometimes fixes it, and sometimes opening the System Monitor can trigger it, other than that, I don’t have solid repro steps. I don’t think it’s happened when used with the 3 monitors at my PC, only with the TV.

using udevadm monitor and journalctl -f, the only clue I see is the following:

Mar 01 02:40:31 suse-desktop org_kde_powerdevil[2454]: [216114] Udev event detected

Is there anyone that might be able to help me with this? I’m not really sure how to debug this further.

Thanks!

Please start by providing comprehensive graphics hardware, driver, and environment details: inxi -GSaz

Is VRR / Adaptive Sync in use? With the TV connected run
kscreen-doctor -o

Consider disabling it if it is in use as a test with
System Settings → Display & Monitor → Adaptive Sync → Never

Any difference in behaviour?

And were you able to disable VRR via Systems Settings? Drop to a lower refresh rate? Any difference?

I haven’t had a chance to test yet but I will update when I can, it’s low repro so it’s hard to pinpoint a definitive fix. Switching to TTY or hard resetting my TV (power cycle from the wall) sometimes fixes it too.

Sorry for the delay, after a clean install and VRR disabled in KDE, I hard froze during a game, and then hard froze again after a reboot as soon as I got onto the desktop, and a third time.

Journalctl didn’t output anything useful, I might try another clean install and see what happens as I’m not sure how to even begin diagnosing this.

I’m not convinced about reinstalling being a means to resolution here, but at the same time only a bit of time and effort on your part. Hard freezing immediately on the desktop is more likely a hardware, firmware, or low-level GPU driver issue rather than a KDE/Tumbleweed problem. Ensure the RAM and the GPU card is properly seated, and PSU connections are solid. I’d also recommend testing using a live USB perhaps, and observing if the same issues are experienced.

Thank you for the response, the reinstall was for unrelated reasons unfortunately - will try what you suggested. Thanks again!

So I crashed again, and my third monitor which is connected to my iGPU dropped to TTY and showed some helpful output:

This appears to be an issue with my WiFi driver, I don’t use WiFi so in the installer I set ‘Activate’ to ‘Never’ (I usually just leave it as is, and never had a problem) I assume this could be causing this crash, can I just find the module, blacklist it, and rebuilt the initrd?

Also, I tried gaming last night without Gsync and I didn’t see a stutter issue yet, however the game was noticeably not as smooth, so hopefully I can figure out how to prevent the stutters.

I was looking through the YaST installer source code to see what exactly the installer did when I selected Never so I could try and get a solid repro, but for now I’d like to just blacklist it as I use ethernet anyway.

To prevent any rtw89 driver from loading, create /etc/modprobe.d/blacklist-rtw89.confand add them like this

# Blacklist all Realtek rtw89 Wi-Fi drivers

# Core / helpers
blacklist rtw89_core
blacklist rtw89_pci
blacklist rtw89_usb

# USB adapters
blacklist rtw89_8851b
blacklist rtw89_8851be
blacklist rtw89_8851bu
blacklist rtw89_8852bu

# PCI cards
blacklist rtw89_8852a
blacklist rtw89_8852ae
blacklist rtw89_8852b
blacklist rtw89_8852be
blacklist rtw89_8852bt
blacklist rtw89_8852bte
blacklist rtw89_8852c
blacklist rtw89_8852ce
blacklist rtw89_8922a
blacklist rtw89_8922ae

Reboot, make sure none are loaded: lsmod | grep rtw89
and rebuild initramfs with sudo dracut -f.

Thank you, I actually just did this as I got your reply! I’ll see if the original stuttering bug reproduces today now that this is solved, I appreciate your help!
