Nvidia RTXA2000 - differences between manjaro and arch

Hi all,

During the setup of my new laptop (hp g8 - rtxa2000) I’ve successfully installed Manjaro (i3 / Xorg) with proprietary drivers. Graphics card is recognized and nvidia drivers are loaded.

On Arch, however, I can’t seem to get the system to work. I’m interested to learn about how Manjaro handles the drivers in this case, and to figure out the differences between the two systems.

nvidia-settings lets me know the driver version is 510.73.05. I’ve tried rolling back Arch’s nvidia driver to 510.x, as well as the related linux kernel. That didn’t work out, so perhaps there’s some additional configuration that I’m unaware of?

Manjaro adds a lot of effort into the easiness of installing Nvidia drivers.
The mhwd application and different versions for different GPUs, just to name two.

In Arch, you’re generally personally responsible for everything. You might ask in their forum how to install these drivers.
