I used Arch/EOs with a very old NVIDIA GPU for some years (390xx drivers), normally the AUR packagers include, when needed, a patch for newer kernel version, so it should be ok-ish (at least on XOrg).
Just pay attention to:
- initial driver choice (
dkmsvs kernel-specific) - updates:
- always wait a couple of days and check AUR comments relative to your driver, normally problems will arise there
- always read the output of init regeneration (mkinitcpio/dracut…) for eventual issues to be solved before rebooting
- in the event of a driver failure (typical black screen on startup), repress the urge of a long sequence of blasphemies and boot up a live iso, chrooting on your system and attempting to downgrade (if you’re on BTRFS with a sane snapshot workflow, you can attempt a much easier rollback).
That’s at least my experience (rather patchy and unprofessional, naturally) with an old NVIDIA card…it’s manageable and you can leverage an old-still-good card that way…hope it helped
