HIgh CPU use by Xorg with Kernel >=6.12

Support Kernel
1

Pulling my hair out trying to determine the issue here because it is preventing me from updating my system. As titled, if I use Kernel 6.12 or higher, I experience 80-100% CPU usage and lag by Xorg when simply moving my mouse or dragging windows around. This will make the windows stutter as they’re being moved across the screen or the mouse cursor will start jumping as it tries to catch up. Any kernel below 6.12 will perform just fine - Xorg typically won’t break 10% CPU usage at all.

I’m currently running Kernel 6.11.11-1 (yes, I know it’s EOL) because everything actually works properly with it. Downgrading to 6.6.75-2 is not an option for me as I lose the ability to control the fan curve of my 7900 XT and generally experience lower performance from it.

I’m just not sure if this could be a kernel driver issue or some sort of Xorg config weirdness. This machine originally had an RTX 3080 in it when Manjaro was installed, but I eventually swapped it for the AMD card and removed all of the Nvidia software.

Additionally worth noting- I have previously updated to the latest stable build (25.0) and attempted to use both kernels 6.12.12-2 and 6.13.1-2 with no change. I still experience this issue with everything updated, so I rolled back via Timeshift to get back to 6.11.11-1.

Hello and welcome to the Manjaro Community!

Unfortunately the information you posted is truncated: it is recommended to post the full output of

inxi -zv8

… and use code formatting; one way is to add 3 backticks ``` or three tildes ~~~ on empty lines above and below the pasted output; another is to highlight the pasted text and click the </> button at the top of the reply window. :wink:

This way, we will have a better idea of the system you are running.

Cheers! :smiley:

Thanks for this! As I see you are using Xfce, I am aware of some issues but since I’m on Plasma, hopefully people more familiar with Xfce may be able to help.

I was going to suggest switching to Wayland, but I don’t know if that works in Xfce yet. If not now, hopefully soon. :man_shrugging: :wink:

I wonder why you would have Xwayland installed.

Wayland - ArchWiki

Have you been through this Arch Wiki, section 2 in particular?

AMDGPU - ArchWiki

I’m not 100% sure, but I think Xwayland installed by default when I installed Manjaro. I don’t recall the build version at the time, but I installed this system in early December of last year with the RTX 3080 in it, then swapped to the AMD card a few weeks later.

I’ve been through the AMDGPU Arch wiki and tried a few of the .conf settings with no luck. I’m still just completely stumped as to why this occurs only with kernels 6.12 and up.

I’ve also tried disabling auto-start applications and services one by one to see if any particular bit of software would be tripping things up, but no luck there either. :face_with_diagonal_mouth:

… unlikely, but possible, given that Xfce4 does not yet deal in wayland …

What I tried to suggest was to get rid of it - and see whether it improves the situation.

At the moment there is also nothing that forces you to use kernels 6.12 and up - or is there?
Use what works?

Unfortunately the removal of Xwayland doesn’t make any change.

The whole reason I’m trying to troubleshoot this is the fact that the 6.11 kernel series is EOL and no longer supported at all. They’re removed from the repos, meaning that I cannot upgrade my system any further without moving down to 6.6 and lower, or moving up to 6.12 and higher. 6.6 and lower is not an option as I lose the control over my GPU’s fan curve and a few other pieces of hardware seem to have random issues with the older kernels.

I’m sticking with 6.11 for now as it works perfectly fine, but I’m going to keep investigating because I’d like to be able to update at some point soon. It’s just bizarre to me that Xorg completely pegs out random single cores on the CPU in the newer kernels.

I think the next course for me is going to be booting a fresh live image and seeing if the issue remains while isolated away from my existing install.

There will be no Xwayland there - and if I where you, I’d have already tried this :grin:

Interestingly enough, the issue persists when booting Manjaro XFCE live USB which is using kernel 6.12…

I also booted EndeavorOS live USB using KDE environment, which was using kernel 6.13.1-arch2-1 and the issue persists there as well.

Such a strange problem. :thinking:

Kernel 6.6 is still supported for several more years. Give it a try.

I resolved the issue by adding the following line to /usr/share/X11/xorg.conf.d/10-amdgpu.conf-

Option "SWCursor" "True"

I’ve confirmed this does indeed fix Xorg’s extreme CPU usage when moving the mouse around the desktop in Kernel 6.12+ for me. It has the unfortunate side-effect of causing the cursor to flicker wildly in some applications like Steam and occasionally in Firefox, so it’s not quite an optimal fix for me in terms of usability, but it does solve the original issue of single-core CPU spikes. For that reason, I’ll mark this as the solution.
