Fresh arch install W/ NVIDIA - Visual Glitches (KDE Plasma W/ Wayland)

Sodx · 2024-02-10 02:25:33

Hello, I am fairly new to the scene. I have a good understanding of Linux and decided I want to dive into Arch. I followed this tutorial to install: https://www.youtube.com/watch?v=_JYIAaLrwcY along with the official install documentation, but I get some visual bugs that I would otherwise not have if I were to use the install script.

netfetch:

OS: Arch Linux x86_64 
Host: MS-7D98 1.0 
Kernel: 6.7.4-arch1-1
Packages: 1194 (pacman) 
Shell: bash 5.2.26 
Resolution: 2560x1080 
DE: Plasma 5.27.10 
WM: kwin 
Theme: [Plasma], Breeze [GTK2/3] 
Icons: [Plasma], breeze-dark [GTK2/3] 
Terminal: konsole 
CPU: 13th Gen Intel i9-13900K (32) @ 5.500GHz 
GPU: NVIDIA GeForce RTX 4080 
GPU: Intel Raptor Lake-S GT1 [UHD Graphics 770]
Memory: 3905MiB / 128581MiB

I have been searching for several days on possible fixes to visual artifacts for days and have yet to find an actual fix.
If you need extra information, I will gladly provide that for you.

This is the kind of artifacts that I see: error

===================FOUND A FIX===================
Following section 10 HERE is important for ensuring your screen does not crash when going from hibernate (or similar) back to "awake"
I had also edited /etc/pacman.conf and added:

[kde-unstable]
Include = /etc/pacman.d/mirrorlist

After, run sudo pacman -Syu then reboot.

I followed this tutorial to install: [idiot on youtube] along with the official install documentation

https://wiki.archlinux.org/title/Installation_guide

This is the kind of artifacts that I see:

That's called https://en.wikipedia.org/wiki/Moiré_pattern and happens when you take a photo of pixels.
Can you actuall see the Moiré pattern with your eyes?
Please post your Xorg log, https://wiki.archlinux.org/title/Xorg#General

Calm yourself; the "idiot on YouTube" was also following the installation guide. I was following along while cross refing with the install guide as well.
The only difference from his video and the install guide was:

Installing NVIDIA drivers
Setting up pacman hook for NVIDIA
Setting modules on mkinitcpio.conf
Setting nvidia-drm.modeset=1 in the boot loader entry

I probably should have been more specific about what I was seeing. The picture is showing Konsole with a transparent background and "blur background" enabled. When I move my mouse across it, it makes those lines where the mouse was. I couldn't take a screenshot because any sort of screen refresh makes it go away.
Anything with a slight transparency does this. There is also a slight problem with screen flickering, the most notable instance is watching the download screen update on steam while downloading a game.

Also, I am using Wayland plasma.

I am calm and I let you calmly know that anyone who thinks it's possible to present the installation process in a linear format or spend time reading a wiki that's in constant flux rendering their video dated next weak is an idiot. Likeshareandsubscribe.

I thought you had used some screen painting tool there.
Did the youtube idiot also point out that KDE/wayland is still work in progress?

Try to

export KWIN_FORCE_SW_CURSOR=1

(KDE needs to see that so in doubt use /etc/profile.d/*)
If that doesn't help, please post your complete system journal for the boot:

sudo journalctl -b | curl -F 'file=@-' 0x0.st

The problem doesn't exist on X11?

For the records, your xorg log is from today and suggests that you're forcing the X11 server to run on the nvidia GPU because you created a conifg file w/ nvidia-settings or nvidia-xconfig, what even for xwayland, is not a very good idea at all.
You might rather want to remove that, resp. replace it w/ something more narrow and dedicated like https://wiki.archlinux.org/title/PRIME# … rimary_GPU (you cannot copy and paste that, it's just a config pattern) or, ideally, simply deactivate the IGP in the BIOS, if that's an option.

To others having the same issue as I am, the potential solution that worked for me was appended to the original post. Do note that it will use an "unstable" version of plasma, though it has not given me any issues, even with gaming. Your outcome may be different.

Your "fix" is misleading.
https://wiki.archlinux.org/title/NVIDIA … er_suspend will prevent completely garbled or black textures after an S3 but the original was not "also", but "fixed" by advancing to (the unstable) KDE6 development tree, what is fine if it works, just something to be aware of

Please always remember to mark resolved threads by editing your initial posts subject - so others will know that there's no task left, but maybe a solution to find.
Thanks.

Well good thing it's not a staging branch.
