I have tried reinstalling garuda twice but it still freezes abruptly

EDIT- I managed to solve it
Apparently my Kscreen log was writing continuously and managed to hang the os
"export QT_LOGGING_RULES="*=false"
Seems to fix it for now

It stuck again. I initially thought it might be similar to the garuda stuck after sleep issue but this time it was stuck simply while I was trying to install a new theme

Hi there, welcome!
I'm not an expert on graphic cards, but let me try...
First thing you could try is to boot with another kernel, if available, Eg lts.
The second thing you could do is to try to fully update your system.
Can you open a terminal with ctrl+shift+t?
If not, you could boot to a TTY: press button E at the grub line you use, add a 3 (with a space before...) at the end of the line starting with linux and press ctrl+x.
Finally, I think you could also try reinstalling starting with free drivers, update and then use the Garuda assistant to install the proprietary drivers.


I tried Linux lts and it got stuck too, all I was doing was watching YouTube, ctrl+alt+t didn't work. Although I did manage to play/pause audio(video was stuck) via kde connect on my phone

Is the problem specific to Garuda? Could you try Manjaro if you haven't already as it is also Arch based? I won't be much help but good to know if it's across multiple Arch based distros or not.

Use htop/top in terminal, check which "app" use lot of CPU/RAM

Baloo in action?

Which GPU is used?

Good that you didn't write M$, bad that it had to be this one, what about Arch, what about EnOS?

I switched to manjaro but I had to switch back because the sweet theme integration that I got used to is a bit hard to completely implement (with Latte integration)

Because Manjaro has more support and a bigger community so likely more work done meaning likely to have drivers in place where they may be missing in pure Arch or other less used Arch based distributions. Ain't anything wrong with me suggesting Manjaro considering its popularity

Facebook is wildly popular. . .

If I were me, I'd probably avoid the big M.

edit: I do actually go on their forums - it's amazing how many help threads are there.


I m using a GTX 1650

I can't access htop/top when it's stuck
And after reboot it doesn't show any abnormalities

If it was memory overload, doesn't garuda have nohang already in place to deal with it?

After boot, open terminal and start htop. Not if the problem already exists.

I think nohang might be the culprit all along

What am i doing wrong here
And do you need any other info to help?

Are you on barebones? If yes, then try dr460nized.

I m running Dragonised kde

Are performance tweaks active?
Check garuda-assistent

i have powersave tweaks enabled instead
i read its better for laptops
or should i enable performance tweaks
(will it drain battery faster)
is it possible to create an exception for this service only?

I thought more about overheating but this also happens when the notebook is lying on the lap/blanket.

Then the PC "freezes".

i always make sure to have proper air flow and low pc temps
also i dont really use heavy apps for it to overheat

I'll try performance tweaks for now and see if my battery takes a hit or not
