It’s the only issue I have on my CachyOS install on an AMD 5900X+9070XT without additional peripherals. It seems like when I hit sleep it doesn’t manage to fully enter sleep (illustrated by the power lights) and then never wakes up anymore until a hard power reset.

I've had wake-from-suspend issues on plenty of non-nvidia machines, and I have had nvidia machines that have no issues.

I think it has nothing to do with the GPU and everything to do with the motherboard chipset.

Agreed. AMD just works for me on linux. My problem is that I am addicted to 6+ monitors and top end gpus... nvidia just seems to hate linux for top end setups. Which is sad, windows just handles my dumb 5060+5090 setup easily. Gaming on linux has gotten way better, but I still can't gigure out how to get some games working. So I'm stuck between using linux + sway / i3 which I looooove... and not being able to get the value out of my $6k gaming rig. Sadly this is a tale that's been going on for 20 years for me.

Linux Mint works great with nvidia cards. It has a great driver manager. It is the only distro I found after getting a laptop with a RTX card that just works. It has worked flawlessly too after 8 months of use.

Does it work with two and sway though?

Is it also doing great with the 58xx driver series that is now mandatory on arch for models a couple years old? I've been having severe issues since then to the point where I had to borrow an AMD GPU from a friend just to get my working station up and running again

I personally like mint too for the past 10 years. They also decided to go against the grain of Ubuntu and not ship things like firefox in a snap, which I prefer.

People tease mint as being a distro for normies and grandmas, but it has worked flawlessly for me and really all I want is an environment which just works.
