MHWD quits when I try to install NVIDIA driver

I’m trying to update my NVIDIA driver. Currently, I have video-hybrid-intel-nvidia-440xx-prime installed. I would like to install video-hybrid-intel-nvidia-450xx-prime, so I typed the following command:

sudo mhwd -i pci video-hybrid-intel-nvidia-450xx-prime

But this just does this:

> Dependencies to install: video-modesetting
Proceed with installation? [Y/n]

After I type “Y”, mhwd just quits, with no further output whatsoever. The reason I want to install the newer driver is that when I try recording with OBS using the hardware encoding, it doesn’t work, and says I should install a newer driver.

So, does anyone know why this is happening?

This is a bug, please install video-modesetting and try again.

How can I install video-modesetting? I can’t find it with pacman -S video-modesetting or yay -S video-modesetting

You need to install first video-modesettings

sudo mhwd -i pci video-modesettings

Ohh I see, I’ll try that, thank you

Well, it fixed that, but now I’m getting this error:

[j4cobgarby@j4cobgarby-desktop ~]$ sudo mhwd -i pci video-hybrid-intel-nvidia-450xx-prime

Should I uninstall the previous driver?

Remove nvidia-prime (and other offending packages - not blindly!) and reinstall it after the 450xx driver has been installed.

That worked, thanks
