OpenRGB doesn’t list support for my Gigabyte mobo

Unfortunately, this is still relatively common on Linux, but it’s not really a Linux issue, but a manufacturer issue. The manufacturers should be the ones supporting Linux, not the other way around.

The situation is getting better, so when it comes time to upgrade, you can find something more open so you’re not beholden to some random software and have more choice.

AMD adrenalin only lists 3 distros

Honestly, I don’t see the point of adrenalin on Linux. For framerate locking, use libstrangle or mangohud. Don’t bother with OC, it’s honestly not worth it (if you really want to, it is totally possible).

I don’t know what else Adrenaline provides, but I’m sure there’s a way to get what you want on Linux.

apps

This is absolutely hit-or-miss, and IMO a bigger issue if you really need something that’s not properly supported on Linux. If it’s not in the repositories or in flathub, IMO, don’t bother if it’s going to be a dealbreaker (esp. Adobe products).

But if you’re fine using an alternative (e.g. LibreOffice for office software, likewise for any other apps), then give WINE a shot, maybe you can keep your same workflow. Or if it’s really only for an occasional thing either run a VM (if it’s not performance sensitive) or dual boot. I have a drive w/ Windows installed just in case I need it for something, but I haven’t booted into it for something like 2 years now. But it’s there if I ever actually need it (will need a ton of updates though).
