Gnome laggy after update

Support
1

I am not sure what to do and wanted to ask you guys for some advice.

While this update did not cause any problems on my desktop computer (a Ryzen 9 3900X based machine with two Radeon Pro WX 7100 GPUs built around a ProArt X570-Creator WiFi mainboard by ASUS).

On my Z16 AMD Lenovo ThinkPad, however, the system has become super slow and laggy since updating. I can feel it most clearly in the GNOME animations. They stutter and sometimes even get stuck for a second or so. But it’s not always the same level of bad. Sometimes, however, after a while the mouse pointer moves with such great latency that I can no longer click anything reliably.

I suspected Firefox to be the cause since I read a lot about memory leak issues in conjunction with some extensions. However, I experience the lag also when Firefox is not running.

I keep my desktop and my laptop strictly “in sync”. Meaning, I maintain the same packages and kernels.

I can’t see anything outstanding in journalctl and even with top there do not seem to be any drastically resource consuming processes.

What would be a good way to analyze such a problem?

These are the details for my computer that is having problems with the update:

Many thanks for your advice in advance!

From some kind of *fetch script?

This is suboptimal.

I see you are on 6.11 - the latest kernel in stable branch is Linux 6.12.1

It is quite possible you could benefit from syncing.

sudo mhwd-kernel -i linux612

With everything newer than kernel 6.11 I get graphical glitches, unfortunately.

I run a ThinkPad X13 AMD laptop (7840U APU) - no issues on 6.12 - using Plasma - so there is that.

It may be connected to the mutter window manager but I have no means of checking.

Interesting! Maybe I can boot Plasma from a USB stick soon and verify that for myself. Thanks for the hint.

I can confirm there’s a problem. Not to the same extent, but especially with the Gnome apps (calculator, settings, extensions etc.) there is a notable delay of up to >5 seconds when opening the app, which is completely unusual

Don’t know if this is helpful, but:

It may be connected to the mutter window manager but I have no means of checking.

the 16-12-2024 update had an update from mutter 47.2-1 to 47.3-1, so this may be related?

That would mean that both AMD and Intel based systems could be affected.

Previously, I was thinking that it might be connected to any of the AMD related kernel parameters I have set in /etc/default/grub:

udev.log_priority=3 splash amd_pstate.shared_mem=1 amd_pstate=active

I added some of them over a longer period of time and don’t remember the exact circumstances anymore, which are standard and which I added, etc.

Should I maybe try to temporarily disable some of them to track this problem down further?

amd_pstate args are not default.

As noted above mine is 7840U and yours is 8845HS - and I don’t use those - they may be needed on some system - but I have no details.

And since an Intel user has - somewhat - similar issues it is more likely the window manager causing this.

Using a live ISO (ventoy) with the official images could provide insight with affected systems.

The lates images is labelled 24.2.1-241216 and is available for download, using the website or using our tools.

Using the Live ISO, I can confirm that I do not have any lag. I do have a lot of GPU glitches, but that’s another story.

These are (almost) all benign or desirable.

  • udev.log_priority=3 minimizes log output. Really just doesnt print systemd version.
  • splash is for … boot splash … particularly plymouth.
  • amd_pstate=active is one of a few pstate options. See here.
  • amd_pstate.shared_mem=1 … I have trouble finding documentation for, relevant docs anyways. It seems to have been required in order to use amd_pstate at one time.
    (I use amd_pstate, but not this option)

Back to ‘laggy’ …
If you are using gnome, then after obvious basic configuration or hardware, the first guess is always extensions.
Disable them all and see then.

Thanks for the background information.

Meanwhile I found my notes from when I added the AMD related kernel parameters:

Enabled AMD CPU power states and GNOME’s CPU power state governor GNOME shell support via systemctl enable cpupower.service, pamac install power-profiles-daemon, systemctl enable power-profiles-daemon and by adding amd_pstate.shared_mem=1 amd_pstate=passive as kernel parameters to the end of GRUB_CMDLINE_LINUX_DEFAULT= via sudo nano /etc/default/grub followed by grub-mkconfig -o /boot/grub/grub.cfg.

I did this back then because I wanted to be able to switch between the power state governors in the GNOME shell top right menu.

Anyway, I just removed these kernel parameters, rebooted and wow, the lag is gone. \°/

Now that I make this connection, it almost seems as if the computer was always running in the Power Saver state before, regardless of which setting was selected (Performance, Balanced or Power Saver).

I would not have expected that but will keep an eye on it for a few more days and then come back here to mark it as the solution to the problem.

Thanks for your help again!

Nice … except it still does not tell us is amd_pstate.shared_mem=1 is actually needed. It does not exist anywhere on the archwiki for example.

Also …

Wouldnt power-profiles-daemon conflict with cpupower ?

(Not the packages themselves … cpupower provides various tools … but the services)

15

Unfortunately, I don’t know the answers to your questions :frowning:
I can’t remember how I got the information or the steps I performed. But back then it worked fine. Whether all these parts were necessary, or some of them even conflict with each other, I cannot say.

But I have now been working with the laptop for a few hours and can definitely confirm that everything is back to normal. :slight_smile:

16

You mean after doing nothing?

Im pretty sure cpupower.service should not be enabled at the same time as power-profiles-daemon. But I dont use either… so… :person_shrugging:

All it does is load/apply your cpupower settings at login. But its possible that whatever frequency settings being applied conflict with power-profiles-daemon.

Oh, there is some vague forum example…

17

No, not nothing. :slight_smile: I removed the kernel parameters amd_pstate.shared_mem=1 amd_pstate=passive, rebooted and the lag was gone.

It seems that the computer was always running in the Power Saver state, regardless of which setting was selected (Performance, Balanced or Power Saver).

Anyway, now the system is snappy again and I can still change the power governors in the GNOME Shell.

I will, however, look into a possible cpupower.service and power-profiles-daemon conflict.

Thanks again for your help!

You probably want to keep some iteration of this.
But if you intend to use PPD then you might wish to use amd_pstate=active to use amd_pstate_epp, and have it hint according to PPD.
(Still disable cpupower.service … though maybe it was creating no issues because it was never configured, such as in /etc/default/cpupower)
