Nouveau modesetting driver

General system Kernel, boot, graphics & hardware

Is there an updated version of this guide?

This does not seem to apply to newer installations.

If you have a newer installation it would be using dracut. Is your installation systemd-boot or grub? Or if you are doing a fresh install? Also what is your nvidia gpu?

Edit: Are you trying to revert to nouveau from an nvidia driver?

My installation uses dracut. It’s a grub installation, since this PC only has a legacy Bios. The install was made with the latest ISO image. I already successfully got rid of the Nvidia driver when there were problems with some of the recent kernel updates. Since the performance for my needs doesn’t differ that much, I intend to stay with the Nouveau driver. I want to get rid of the xf86-video-nouveau package due to the tearing problems especially when playing videos. So I want to use the built-in kernel modesetting driver.

nouveau is the open source kernel module which should automatically load on system boot. Have you tried uninstalling xf86-video-nouveau

For the DDX driver (which provides 2D acceleration in Xorg), install the xf86-video-nouveau package.

According to the link I posted in my first post one is supposed to execute

`sudo pacman -R xf86-video-nouveau`
sudo nano /etc/mkinitcpio.conf
Then go to the line
`MODULES=()`
And change it into:
`MODULES=(nouveau)`

This file seemingly doesn’t exist on a dracut system

ls /etc | grep mkinit
ostree-mkinitcpio.conf

cat /etc/ostree-mkinitcpio.conf
HOOKS="base systemd ostree autodetect modconf block filesystems keyboard fsck"

I now uninstalled

xf86-video-nouveau

Strangely my login Screen doesn’t show because of an unsupported resolution. Nevertheless I’m able to enter the password blindly and the Plasma Desktop starts.
Video playback seems to be fine now.
