Optimization for laptop manjaro i3

Well I have also 4 threads with 2 cores:

Thats is pretty normal on firefox for me.

I tried a bunch of kernel already.
4.19, 5.4, 5.10 and now 5.15
And It’s all the same.

I still can’t get terminal to keep firefox in it.
it launches firefox but doesn’t leave a trail.

Could be maybe problem that the temp of the cpu is unknown?

sensors

This will detect them:

sudo sensors-detect

Maybe follow this wiki article: Fan speed control - ArchWiki

I tried sudo sensors-detect, still shows the same sensors which are amdgpu-pci-0300 and pci adapter.

is possible that it’s normal since it’s an integrated gpu into the cpu?

It seems to me you have a graphics problem with that video card and the kernel. There is a similar report here: Latest Linux Kernel dislikes Rzyen Vega Mobile / Kernel & Hardware / Arch Linux Forums

Seems like you might have to add a kernel parameter to the boot line in grub:
“iommu=pt”.

Let us know if that works for you…

ok, I added iommu=pt to the grub boot line.
But it didn’t seem to have any effect.

I don’t know if it has anything to do with the problems but when I was testing to add the kernel parameter from grub directly by pressing e on the grub menu (before writing it down in the grub.cfg) , the fan was spinning like crazy.

I assume you then ran “sudo update-grub” afterwards ?

yes indeed :wink:
