Manjaro kde with kernel 6.1 big performance improvement

Support
1

Hi,
I had a random freeze like usual so decided to test kernel 6.1
after reboot i immediately realized that my pc connected really fast to wifi, before it takes 2-3 seconds to connect, but now its immediately connected. after that i noticed that every thing works faster than before

also i didnt had random freezes with kernel 6.1 for 3 days

is it really because kernel 6.1 ?!
typical manjaro installation with hibernation and ext4

If you have noted a difference after syncing your system to 6.1 then your are correct - I assume you did

sudo pacman -Syu linux61

In that case you have also synced other packages - and then you can make no certain decision if it is the kernel or something else.

I have been using 6.0 and now 6.1 for a while - even custom build 6.0 directly from kernel.org - but I have not experienced any freezes either - so noone knows for a fact unless the kernel is verifiable the only thing synced.

I envy you guys cause im too scared to try…
(I’m a nVidea user, and no idea if the driver will work on that kernel)

It would likely work

  • I would install the headers, dkms and nvidia-dkms for the current kernel
  • then reboot to verify the driver works
  • then proceed with linux61 and linux61-headers
  • reboot and see what happens
  • the biggest risk is failure and you still have two kernels which you can choose from after holding Shift key while booting.

i updated the kernel by using kde settings > kernel

If you are certain you have not updated other package and the kernel has hit the peak performance top with your system

The reason i was scared was because, IIRC, manjaro was dropping support for nVidia cards last time i was using Manjaro.
(But as you’ve noticed i recently came back)

I decided to try anyhow, and what ya know…
I’m now on kernel 6.0 incl. nVidea and broadcom-wl, working good so far (crosses fingers)

I just have a random problem with my wireless port not being activated/recognized, but that is same on normal kernel also since a few days, no idea why but a few reboots fixes it.
(might be hardware on motherboard breaking slowly on this machine i think [hope not])

That’s a test for another day, enough excitement for today :rofl:

I don’t think Manjaro will drop Nvidia in the foreseable future - but who knows what happens tomorrow - I don’t.

I believe you are talking about the old cards which was caused by Nvidia dropping the drivers < 390 I thnk.
