Wayland, Plasma, or Nvidia ? [nvidia 750Ti, 580 drivers]

I have a problem I’m at a loss to diagnose, so maybe someone else has been affected. I have two computers that are rather close in specs, one with a nvidia1050ti, the other a 750ti. On the first one, I have the 580 drivers and the computer runs fine. On the other, which was on the 575 line of drivers, I wanted to go to 580, because I couldn’t find a linux70-nvidia-575xx package to update the kernel. Strangely, the computer boots to sddm, but KDE doesn’t load (or doesn’t appear to load as the screen goes to sleep), and worse, ctrl+alt+F3 doesn’t open a text console (hence why I’m stuck to diagnose the problem). Going back to 575 fixed the problem, but I still can’t run the 7.0 kernel for lack of driver.
So if anyone has a solution, or at least an explanation ?
Thanks,
M.

Hi @mauve02,

I think the easiest in your case would be to use nvidia-driver-assistant. Make sure it’s installed first:

sudo pacman -S nvidia-driver-assistant

Then run it as a normal user:

nvidia-driver-assistant

Sample output:

Detected GPUs:
  NVIDIA GeForce GTX 960 - (pci_id 0x1401)

Detected system:
  Manjaro Linux 

Please copy and paste the following command to install the legacy kernel module flavour:
  sudo pacman -S linux618-nvidia-575xx

That said, the 750Ti is quite old, so an older kernel and driver might just be what you need and the 6.18 kernel ís an LTS kernel, so it might be the better option to use with a driver that works.

For my sanity I’d rather prefer they both be running the same configuration, if possible, plus I noticed on my machine the 7.x kernel is actually better optimised and the computer runs noticeably smoother. Anyhow. Of course, I can live with the current situation, or I could probably upgrade the GPU, but this is my wife’s computer (previously mine), it has all she can possibly need for the foreseeable future considering her modest requirements and the fact I had about maxed out the config before handing it over to her (I plan to sell the 32GB of RAM in the coming years to fund my retirement plan). So I’m not too keen on throwing money out of the window.
But it bugs me that a machine perfectly able to run the kernel is restrained by a pesky graphical driver.
Thanks anyway,
M.

It’s uncool. But, unfortunately such is life…
