Manjaro 18.04 KDE random freeze

Hello,

From time to time i have issues with Manjaro, i cant really determine at which point this happens. It freezes completely, only thing i can do is hard reset. I believe that both times i have been running same apps, as it is my workstation, so the list is:

VS code,Postman, Skype, chromium, 2 npm scripts in terminator.

Hardware is AMD Ryzen 1700, Nvidia 970, 16gb ram

I tried googling this issue, but i could not find anything on the topic. Any ideas what might be the problem?

Have you tried forum search ?
https://forum.manjaro.org/search?q=KDE%20random%20freeze

Have a look how to provide good information on your help request:

Thanks for the advice. I tried searching forum, did not find solution. Also, since im pretty new to Linux, i have no idea what code should i post, in regards to this problem, so if you have a command that i could input in terminal, i would be happy to provide response

Post the inxi -Fxxxz first, as suggested in the link above, then we move from there.

Oh, i apologize. I edited original post, and pasted inxi output

Things you can try.
First update your system using

sudo pacman-mirrors -f5 && sudo pacman -Syyuu

1 install non free nvidia driver
2 install kwin-lowlatency from aur.
3 update your bios
4 set swappiness to low like 5
5 set CPU governor to performance.

Freezing is mostly related to nvidia

May be you can try this

You could try installing
manjarowish-dark-kde-settings
Package from aur.
It will enable some services.
And have performance settings included.

But you will need to create new user to see the changes

I completed first 5 points, hopefully there wont be an issue from now on. Thanks a lot! Couple of questions though.

  1. Now my cpu average clock is around 3000, even though usage is 0-1%. Is that bad for cpu longevity?
  2. if i install manjarowish-dark-kde-settings can i save all settings and preferences that i currently have, or do i have to start from scratch, since i have to create new user?

Well
Your existing settings will be with your current user.they won't be changed
Only new user will get those settings.

Its okay to use performance governor.
It won't make much difference on CPU life as you are not overclocking it
Just using it without restrictions

Ok thanks for the advice.

I have to mention if some other newbie comes here, i had issues after installing nvidia drivers, as apparently they were out of sync with the kernel, so i had to update my kernel from 4.19(which was default i never wanted to touch that) to 4.9.

Now my question is, should i use some newer version, like 5.1 or something like that, and also, which kernel should be a fallback?

Always have two kernels installed
One LTS another latest stable.
You can try kernel 5.2
Use LTS 4.19 as fallback

that is what i thought as well. Thanks a lot!

i did al those things you said i should. i am using 5.1 kernel. I had another random freeze. Do you maybe have an idea what should i do, or paste some error log or something

Do you use swap
If so is it on ssd
And is your home on ssd?

this is output of fdsik -l

so i guess i did not enable swap when i installed manjaro

Is your /home separate ??

Also check the output of

free -h

When freezing occurs

Also have you enabled systemd-swap
It should have been enabled if you installed settings package.

i treid looking at these files:

/etc/systemd/swap.conf
/usr/lib/systemd/system/systemd-swap.service
/usr/bin/systemd-swap

they are empty.

About that command, when my pc freezes, i can only hard restart it, did you mean after restart to try that command or?

I choose default option when i installed Manjaro, which was delet disk, so i assume /home is not separate

It means you are probably using all the ram
And as swap is not enabled.
It causes hard restart.
So you should enable systemd-swap
Read here for its config

It does not cause hard restart, i am forced to hard restart, because system is not responsive. And about full ram usage, i find that unlikely, first of all, i have ram monitor on all the time in my panel, also, i have 16gb of ram, i almost never go over 8gb

Well I'm out of ideas
You probably have to check what's causing freeze.
And I do think its mostly related to nvidia.
If not its ram issue.

You can try resetting bios settings to factory default.

I am also having troubles shutting down pc and rebooting via gui, i have to type poweroff in order for pc to shutdown, otherwise my cpu just keeps running. You think these two things can be related? Thanks anyway for trying to help :smiley:
