How can I switch to Nouveau? (dual-seat)

I have a dual-seat system. When I try to apply the latest update, only seat 0 works afterwards. Seat 1 remains black.

Seat 0 has an AMD graphics, seat 1 has an Nvidia graphics card.

So I rolled back (timeshift) and am now back to a working system with both seats. I’d like to switch to the Noveau driver before trying the update again.

What’s the best way to do that?

The best way is to uninstall anything Nvidia-related. nouveau is in the kernel, but if you have the proprietary driver installed, it’ll use that instead. So purge your system of anything Nvidia-related.

Manjaro Linux only provided 580 as rolling driver; the rolling driver is now at 590.

I think this means your nvidia-driver-assistant needs an update.

The current package version is 0.23.48.01-6

The current script will likely suggest linux618-nvidia-575xx but you could also use 570xx.

Because the linux618-nvidia is at 590.xx, this will make your 1050 unsupported and likely result in a black screen.

mhwd -r pci video-nvidia
mhwd -i pci video-linux

The 580xx driver may at some future point replace 570xx and 575xx if Nvidia manage to stablise it, after all it is their new legacybranch.

So i did:

trizen -R linux612-nvidia linux618-nvidia nvidia-settings nvidia-utils lib32-nvidia-utils
Fehler: Der Vorgang konnte nicht gestartet werden (Kann Datenbank nicht sperren)
Fehler: Datenbank konnte nicht gesperrt werden: Die Datei existiert bereits
  Wenn Sie sicher sind, dass nicht bereits ein
  Paketmanager läuft, können Sie /var/lib/pacman/db.lck entfernen

sudo rm /var/lib/pacman/db.lck 

I think it has to do with the update notifier in the GUI, because this keeps happening to me.

After a reboot, seat1 is black again. The nouveau driver from the kernel doesn’t seem to understand that it’s supposed to take over. :frowning:
OK, this did not work.

trizen -S linux612-nvidia linux618-nvidia nvidia-settings nvidia-utils lib32-nvidia-utils nvidia-prime 

This did not help to restore seat 1. I had to rolback again (thanks to btrfs and timeshift)

I would have used mhwd to remove the Nvidia stuff. :thinking:

My partner’s system has a GTX 970 (Maxwell) GPU using nvidia 470xx legacy driver
because 570xx 575xx drivers do not have a libxnvctl package for conky yet

$ mhwd -li

The rolling driver does not support your GPU and unless it is a laptop you have no use for nvidia-prime either.

Choose a legacy branch like the linux<kernel>-nvidia-570xx for this card.

I will try this:

It seems that video-hybrid-amd-nvidia-prime is installed, because there is integrated AMD-graphics(seat0) and a dedicated nvidia-card(seat1)

sudo mhwd -r pci video-hybrid-amd-nvidia-prime 
sudo mhwd -i video-linux
Error: invalid use of option: -i/--install

Error: because it seems to be already installed :wink:
:face_with_peeking_eye: because i forgot pci

reboot


This did work so far. seat1 is alive
:partying_face:
Now i have to update and reboot again.


Everything is fine now !

No - the error is because you forgot the required pci argument.

In any case - I glad you got it working :slight_smile:
