Nvidia cards and the way to go with drivers on kernel 5.10

[gdh]

hi folks,

may I ask for an advise on nvidia drivers. On last update I had some issues and it was proposed to not use proprietary drivers.

I use this computer for gaming, so what shall be used for best performance, compatibility (wine) etc.

[Yochanan]

For gaming, you definitely want the non-free (proprietary) driver. Just click the Auto Install Proprietary Driver button there to make sure the right profile is loaded.

[gdh]

thanks for that.
I did it and this is the output:

Starting
Warning: config ‘/var/lib/mhwd/local/pci/video-nvidia-455xx/MHWDCONFIG’ is invalid!
Skipping already installed config ‘video-nvidia’ for device: 0000:09:00.0 (0300:10de:1b06) Display controller nVidia Corporation GP102 [GeForce GTX 1080 Ti]
Done …

The proprietary drivers should already be installed based on the screenshot (“video-nvidia” - installed).

[gdh]

ahh okay, wasnt too sure because video-linux seems also installed.

so system takes whatever is most performant?

@gdh

Warning: config ‘/var/lib/mhwd/local/pci/video-nvidia-455xx/MHWDCONFIG’ is invalid!

Hmm, apparently you’re not the only one:

[Stable Update] 2020-12-30 - Kernels, KDE, Cinnamon, LibreOffice, Python 3.9, Mesa 20.3.1

Hi, I uninstalled the driver and then reinstalled it using the following commands: sudo pacman -Rdd linux54-nvidia-455xx nvidia-455xx-utils sudo pacman -S linux54-nvidia nvidia-utils Everything worked too. But now there is a warning message in Manjaro-Settings-Manager about MHWDCONFIG. I initiated this as a test and that’s when I noticed it. Do i have to change it for future updates? And if so, how? Or can i ignore the message? That’s under “show details”: Starting Warning…

@gdh

so system takes whatever is most performant?

Not exactly, though if video-nvidia is installed it will use that.

What’s the output of

mhwd -li

It should be:

--------------------------------------------------------------------------------
                  NAME               VERSION          FREEDRIVER           TYPE
--------------------------------------------------------------------------------
          video-nvidia            2020.11.30               false            PCI

Also the following should list nvidia as the driver:

inxi -G

and the other one:

[desktop@desktop-systemproductname ~]$ inxi -N

not exactly what is expected…

[pobrn]

I think @Yochanan meant inxi -Gazy (or similar).

[gdh]

yep:

Oops. Indeed I did. Post edited for posterity.

@gdh

driver: nvidia
v: 455.45.01 alternate: nouveau,

As you surmised, nvidia is taking priority so it really shouldn’t make any difference.

However, if you want to avoid MHWD errors, you can remove the free driver:

sudo mhwd -r pci video-linux

[abz7]

I was just wondering… I had the exact same problem. Is this the way forward for the mhwd? Meaning, Is it only me seeing a “video-nvidia” now instead of a list of specific drivers…aside from the older 390? Or is something still technically broken with my installs?

Hi @abz7,

No, I don’t think anything’s broken. Yes, this is how things are going to stay.
The process has been changed significantly.

[abz7]

Ok Thanks so much!.. Since it’s arch… I can sometimes get OCD… want things to be up to date and look/work correct
