Common seemingly random stuttering

[ReptilianD]

In the last couple of months I have been having my system slow to a crawl for 10-30 seconds seemingly at random, for example when watching videos in a browser with nothing else open, or playing games that are not resource intensive. This slowdown doesn't seem to be application specific, nor a result of a spike in cpu usage or something similar, having system monitor open while it happens shows no major deviation compared to the moments leading up to it. This will slow down literally everything, down to the mouse cursor, which is why I think it might have something to do with the OS rather than anything else, but I have no idea how to troubleshoot it.

Please generate an overview of your system like this:

- Launch a terminal window (this is how to launch a terminal window);

- Make the terminal window full screen, to avoid chopped lines;

- Copy/paste this command into the terminal:

Code: Select all

inxi -Fxxxpmrz

(if you type: the letter F is a capital letter, and don't omit the space after inxi!)

Press Enter.

Copy/paste the output in your next message.

In the last couple of months I have been having my system slow to a crawl for 10-30 seconds seemingly at random, for example when watching videos in a browser with nothing else open, or playing games that are not resource intensive.

So this began around the beginning of this year?
Did it happen around the time you upgraded from LM21.2 to LM21.3?
Does it go back to normal speed after a certain period of time?

If you open Update Manager and select View > History of Updates, you can see what changed around that time.

Yes, some time between December 20 at earliest and January 10 at latest i would estimate roughly, indeed upgrading to 21.3 was around this time, and also nvidia 535, but i just looked and 545 is available so I will see if that might fix it?

You can take a Timeshift snapshot and then try the newer driver, but I would suspect it is more likely something happened in the upgrade.

Did you check the History of Updates?

Yeah no, the driver did not help.

Yes yes, I did check it, in particular a package called base-files went from 21.2 to 21.3 on the 16th of January, I don't know if that's just a coincidence or tied to LM, but also mint-upgrade-info mintinstall mint-common and others were updated at the same time. This is outside of the range that I thought the issue started but I really might just be misremembering

[ReptilianD]

Also, it does go back to normal after those 10-30 seconds. And I was considering "reinstalling" LM, but even though I have a separate home partition I didn't want to do it until I had more time to figure out what is and isn't on my root. I also don't know how often that will fix an issue either..

I suggest trying the 6.5 HWE kernel (available in Update Manager) before trying a re-install (which might not do anything).

You may have to use the grub menu Advanced Options to select the 6.5 HWE kernel as the OEM may be the default because of numbering.

Are all the videos/games coming across the internet when this happens or are some local to your computer?

The videos are on youtube, and the same game has the same issue whether my wifi is on or off, it has an offline mode, though it took longer for a spike to happen this one time i did it offline now. I will update and let you know.

It unfortunately didn't help. I also tried a different desktop environment before, and while for some reason I get way better performance in the game on KDE Plasma when it's not lagging, it isn't immune to spikes. The game is osu! which I don't think matters that much since it isn't the only program/activity in which the issue happens, but I thought I would mention it for completeness; it is perhaps uniquely unplayable with frequent severe and unpredictable spikes like this. Also, audio doesn't seem to be affected at all, in the game or on youtube. Just that it seems like the rendering of everything slows down to 10- fps.

We don't really recommend installing multiple desktop environments. KDE is one which tends to add extra process files that run no matter what desktop is being used.

I don't game, but I found this osu! which may be what you are referencing.

Did you try running the game with Nvidia instead of Intel?

If you mean switching from "on demand" to just the standalone graphics card, I did a while ago and it did not improve anything then, but I did it again now that you mentioned it and I am getting 1000 fps with no problems for ~20 minutes that I played. Could this be because of the new drivers? In any case I don't think the integrated graphics should be THAT bad, and isn't on demand supposed to kick the standalone graphics card when needed anyways? I would definitely like to resolve the issue in that mode also as it's good to not need to switch between them when Im plugged in or not. BTW, whats the best way to remove KDE and the packages that came with it (I like cinnamon more)? sudo apt remove/purge ____?

Could be.

In any case I don't think the integrated graphics should be THAT bad, and isn't on demand supposed to kick the standalone graphics card when needed anyways?

No. I believe Windows may do automatic switching, but Linux-based distros do not.

On-demand mode means both drivers are available and if you tell a program to use Nvidia then it will, but otherwise it will use Intel.

You can right-click a program in the menu and if the app allows it, you can select "run with Nvidia" (which would be for that program only). See the "Nvidia Optimus" section of Linux Mint 20 Cinnamon: New Features for a screenshot (second screenshot in that section). There are some other ways to tell a program to use Nvidia (it depends on the program as to what will work).

I would definitely like to resolve the issue in that mode also as it's good to not need to switch between them when Im plugged in or not. BTW, whats the best way to remove KDE and the packages that came with it (I like cinnamon more)? sudo apt remove/purge ____?

Best way is to roll back to the Timeshift snapshot you took prior to installing KDE. I don't know what others have done to completely remove KDE from their system.

You do not have any sensor applets installed, do you?

somehow it seems I got switched back to the OEM version?
I only have a program called hardinfo that i start from the terminal, I used it to see if I was throttling when the spikes would happen. No applets with that functionality though, would you recommend one?

I think your hardware might be too new. Even the 6.5 kernel does not support it fully. The 6.6 kernel is supposed to bring big improvements to new Lenovo laptops.

You might try the daily build of Xubuntu 24.04, which contains a much newer kernel series:

If that works fine, you can look forward to Mint 22, which is due in July (or thereabouts).

Linux Mint automatically boots to the highest number installed kernel. If you check in Update Manager, you will likely see the oem kernels higher in the list of 6.5 kernels so the top of that list is what is used. If you want to switch to the 6.5 HWE kernel, you need to boot with it and remove all the OEM kernels so Linux Mint then automatically boots to the HWE kernel.

Maybe it's now happening even on Nvidia because you've been unknowingly using the OEM kernel? Try using the HWE kernel and Nvidia. If that is okay, then it seems like this may be a kernel related issue.

It's likely there was an updated OEM kernel around the beginning of the year. You could try an older OEM kernel to see if that clears the stutter problem. If it does, we can check the changelogs to see if we can determine what the issue might be.

I don't really use applets much so I do not have recommendations. I just know many people have run into stutter issues with the sensors applet.
