[SOLVED] Screen artifacts after kernel load intel gpu drivers

Hello

I have issues with Arch Linux and my notebook, I installed the system using "nomodeset" kernel parameter because some artifacts on screen after kernel loads the gpu driver.

Screen on boot without "nomodeset":

The issue happens on Live CD and in installed system, also I tried some other distros and the same problem occurs.

Anyone can help me?

Configuration:
Intel® Core™ i7 9750H
Hybrid graphics RTX 2060 and Intel UHD 630.

Solved with upgrading kernel to 5.4.6-arch3.

Which card is set to 'boot first' aka primary in your bios/uefi firmware ?

This option doesn't exists in bios, the bios seems modified by manufacturer.

Re: [SOLVED] Screen artifacts after kernel load intel gpu drivers

Which laptop model is this exactly? Just from the symptoms this looks like the integrated graphics is not used at all (you'd not need nomodeset, unless nouveau was freezing the system if the nvidia card is in use), and to properly drive the nvidia card you will want to install the nvidia drivers, and set

nvidia-drm.modeset=1

on the kernel parameters to properly access.

FWIW what's the output of

lspci -k

Model: Notebook Samsung Odyssey NP850XBC-XG1BR

Tried the command (nvidia-drm.modeset=1) but no changes: https://imgur.com/OtNjzvO

and this is the output of lspci -k: https://imgur.com/SnaojLq

As expected you don't have an integrated intel card, install the nvidia drivers: https://wiki.archlinux.org/index.php/NV … stallation

And please post text as text next time

Re: [SOLVED] Screen artifacts after kernel load intel gpu drivers

Please post the entire xorg log. Did you do anything else like trying to generate a config?

Also in that screenshot your kernel is outdated as to what it should be (5.4.6-arch3 ), if you forced an nvidia driver installation via -Sy you will have a kernel/module mismatch, run a proper -Syu . If you did run a proper -Syu you might have also not mounted the /boot partition, in which case you will want to do that and rerun

pacman -Syu linux

Xorg is running with default configuration. But, the new kernel 5.4.6-arch3 solved the problem with integrated graphics.
