There are many reasons to dislike Nvidia on Linux. Here is a little thing that bugs me all the time, the updates. Normally the system updates would be quick and fast, but with the proprietary drivers of Nvidia involved, it gets quiet slow process. And I am not even talking about any other problem I encounter, just about the updates.
As an Archlinux based system user (EndeavourOS to be precise), I get new Kernel updates all the time. That means every time a new Kernel version is installed, the Nvidia driver DKMS has to be installed too. And that is basically the slowest part. But that’s not too bad, even though it’s doing this twice for each Kernel I have once.
What’s more infuriating is, if you also happen to use Flatpaks for a very few applications. I really don’t have many Flatpaks at all. Yet, the Nvidia drivers are installed in 7 versions or what?! And they are full downloads, each 340 MB or more. This takes ages and is the only part that takes long to update Flatpak system. I always do flatpak remove --unused to make sure nothing useless is present. /RANT (EDIT: Just typos corrected.)
AUR is not the same as the community repository on other distros though. Community repositories on other distros contains pre-built packages supplied by community members, while AUR contains build scripts that let you download the source code directly from the vendor website, compile it into a package and install it in your system with a single command, so you’ll often get the bleeding edge version faster than most community repositories on other distros.
