Really laggy, like it uses 1% CPU

My arch friend recommended me to make this post since he couldn’t figure it out.

Before I switched to Manjaro I had tried debian mint. It ran fine but it lacked the necessary drivers and my friend convinced me to switch to Manjaro. But during usb boot load I noticed there were significant lag which I initially thought was because of my flash drive but it persisted even after installation. Since then I’ve followed my friend’s recommendation of creating a swap, checking my ucode was up to date, updating my mesa driver, and changing to gnome, to no avail.

Significant lag(1 fps) has not been the only symptom, occasionally my screen has also glitched and froze. It has also in general been unresponsive with some application taking a lot of time to open. My computer is newly bought and my system info is this:

Thanks in advanced.

Edit:

Ok fixed! For future people who may run into the same issue as me, try this:

  • Open up the terminal and write kate /etc/default/grub or on manjaro gnome you can do sudo gedit /etc/default/grub

  • At GRUB_CMDLINE_LINUX_DEFAULT inside the quotes, add parameter i915.enable_psr=0. You add a parameter by adding a space at the end of the text inside the quotes. Don’t remove anything(Although I did it the first time with plasma and it seemed fine but just in case don’t)

  • Save the file, update grub in terminal sudo update-grub and reboot. It should now work

I did this with both Manjaro Plasma and Gnome. For gnome it was extremely obnoxious since the screen flickered at every mouse movement but it fixed itself after changing the resolution to 1920x1200.

Hi and welcome to the Forum :+1:

Can you explain more what you were doing when that happens, and if the 1FPS is from your camera or normal GFX card (eg Anything on your screen)

Hope in mean time there will be people who can assist you, cause it’s my bed time now…
:vulcan_salute:

It’s frame laggy in general, even at the login screen.

4

A random idea: maybe it’s related to power saving? Like too effective or effective when it shouldn’t be?

It could also be a hardware failure: they usually show as the hardware wears, but there is also a possibility to show very early on defective products.
Since you mentioned you already had the issue in liveUSB, you could try to rule this out by testing other live distributions.

I had similar issues when I tried endevourOS after Manjaro. Also it looks like my usb drive died so I’m gonna have to get a new one xd. I believe debian mint worked fine though.

6

All linux distro’s use the same software, just different versions, so that makes no sense…

7

did you tried with different kernels? with the 6.2 and 5.15…
disable baloo - system settings/file search and uncheck all options, click apply;
and try adding this parameter:
kate /etc/default/grub
and inside this line: GRUB_CMDLINE_LINUX_DEFAULT inside the quotes add this parameter:
i915.enable_psr=0
dont remove anything, just add it to existing parameters, save the file, update grub:
sudo update-grub
reboot and test

your cpu is in powersave mode. switch to performance !

Well that seems to be the reality of it so make that what you will of it. I checked again by running debian mint on a usb drive and it does not have issues running smoothly(although my touchpad doesn’t work or my wifi). LDME 5 uses kernal 5.10 so it is an older version than what Manjaro has.

10

I did cpupower set -b 0 and it didn’t have an effect.

11

Unsure how to change kernal but disabling baloo and changing grub seems to have done the trick and now it runs smooth.
