KDE laggy even if I use default theme

[lux_nychta]

Hi

I just installed manjaro KDE on my desktop machine and unlike on my laptop (where I have Manjaro KDE too)
KDE plasma is laggy.

I tried to put OpenGL 3.1 as rendering backend according to this topic

It doesn’t work

So I checked my nvidia driver:

 nvidia-smi

I tried to fix them without results, any idea ? I would like to fix when I use dracula theme but if I can fix only with a default theme it’s ok

[bogdancovaciu]

Hello,

@lux_nychta

So I checked my nvidia driver

But according to your user description, you have a Laptop, and most likely a hybrid GPU one …
To know exactly, here is [HowTo] Provide System Information

[lux_nychta]

Sorry, I made a mistake, I just installed Manjaro on my DESKTOP machine. And I have an issue on this unlike my other Manjaro on my laptop. I edit my initial message

[Olli]

Welcome to Manjaro!

1. Please read this:
   [HowTo] Provide System Information
   and press the three dots … below your post and press the to give us more information so we can see what’s really going on.
   Now we know the symptom of the disease, but we need some more probing to know where the origin lies…
2. An inxi --admin --verbosity=7 --filter --no-host --width would be the minimum required information for us to be able to help you. (Personally Identifiable Information like serial numbers and MAC addresses will be filtered out by the above command)
   Also, please copy-paste that output in-between 3 backticks ``` at the beginning and end of the code/text.

:+1

[omano]

Please don’t use QUOTES to post CODE, it makes it unreadable.

Do it like that

```
your log here
```
so it is readable and properly formatted.

[lux_nychta]

sorry, I fixed that

[JiaZhang]

It seems that Manjaro KDE lag is commonly observable.

There’s a suspicion that it has something to do with baloo, but it’s not confirmed:

KDE Plasma very slow, sluggish, unresponsive

Hello. Last friday I installed the KDE edition Manjaro on my desktop computer. I run six 1440 line monitors on two AMD rx480. Processor is Ryzen 2700x. Most of UI runs very slow. The main menu takes a few seconds, to type in textboxes lags few seconds. Chrome is VERY slow when I type or scroll, while Firefox runs pretty much ok in terms of speed but tabs act funny like they are sometimes not where they seem to be. Konsole seems to run fine. I have tried changing opengl version and disabling …

Manjaro kde open app quite slow compare to other distro(nitrux)/manjaro gnome/mamjaro i3

I just install fresh manjaro kde, and experience this problem, do you guys have any idea where I can track it down Open system setting is quite slow compare with nitrux distro (instantly). Open kitty quite slow compare with manjaro gnome/manjaro i3. Open dolphin quite slow too. inxi --admin --verbosity=7 --filter --width System: Kernel: 5.15.7-1-MANJARO x86_64 bits: 64 compiler: gcc v: 11.1.0 parameters: BOOT_IMAGE…

[omano]

Can you give more detail on what “laggy” means?

Here is how I configure Nvidia on KDE for tearing/smoothness issues Imgur: The magic of the Internet

[lux_nychta]

For example when I go to plasma menu → configuration → system configuration and I click on it, the menu disappears (normal behavior) and before system configuration window appears the cursor freezes.

Sometimes when I watch video, it freezes too

It’s always less than a second for all examples but I think it’s not normal with my hardware

[omano]

I have fairly similar hardware, and don’t have these issues.

Can you try to create a new user, login to this new user, and see if on a default new user you have same issues? Maybe something you installed on your current user is creating the issue.

[lux_nychta]

ok I’ll tryc, give me some minutes

Else I tried “Imgur: The magic of the Internet”
Same behavior

[lux_nychta]

I made a new user and there is the same behavior

[Olli]

let’s check and have a focus to something else. there had been issues with bios settings of the default energy mode inside and the ryzen-cpu. you’re nvidia-driver is set correct and maybe the reason is indeed something else.

A lot of freezes with AMD Ryzen 5 3600

I have the same issue with my Thinkpad E595 running a Ryzen 5 3500U. I have tried all the latest kernels : 5.4 and up. I even tried installing Linux Mint, thinking the kernel version they are using would have that problem solved. It seemed to work without issues from a live USB for hours, so I thought it worked, but turns out it has the exact same behavior now, after I have done all of the updates. I have no issues on my Thinkpad T420 (i7-2720QM), which is also running Manjaro.

[lux_nychta]

So if I understand well my problem comes from my kernel

In manjaro settings → kernels I see many kernels. I’m using 5.15.21-1
wich one should be test ?
I can install :
5.16.7-1
5.16.2_rt19-1
5.17rc… (experimental)

[Olli]

5.16.7-1

[lux_nychta]

Freezes are always here

[Olli]

may i ask if you are on a stable or unstable release ? please post the output of

sudo pacman-mirrors -G

[lux_nychta]

If it can help you, I just made a video to show you an example of freeze:

https://easyupload.io/1193rk

It’s really just little freezes but it’s annoying

[lux_nychta]

@Olli

sudo pacman-mirrors -G

sudo pacman-mirrors -G

If it can help you, I just made a video to show you an example of freeze:

It’s really just little freezes but it’s annoying

Ah … the KDE animation is smooth and actually not laggy, so it’s not the graphics problem.

That kind of little freezing is more related to either the CPU or SSD.

Since you just did a fresh install, it’s probably the SSD that just need some time to accustom itself.

My advice is to use your desktop normally for a longer time.
