[SOLVED] Issue trying to install AMD catalyst drivers

latest post I saw for about the catalyst drivers was five months ago, I've heard that catalyst support for linux is different now. but I'm having issues, here's the log.

I really don't know what to make of this. I'm hoping this will resolve the various framerate issues I've been having with my games. for some reason my processor rate also spikes to 90% for who knows what reason. I really don't know why this would happen, unless for some reason the open-source driver is confusing the CPU for an APU.

you may need to patch it for that kernel https://github.com/imageguy/fglrx-for-Fedora
AMD kinda slacked off was my view of it but made the complete blob open now with the 4.14 kernels. you may want to compile the kernel from current testing.

fglrx won't build with 14.2 or later. AMD never added support for the newer X.org used in those Slackware versions. There's patches floating around to add support for newer kernels, but nothing for the newer X.orgs. In that regard, Catalyst on Linux is dead unless you use an old enough Linux that contains an old enough X.org.

All their work now is going into amdgpu, both the opensource driver and the proprietary amdgpu-pro, but these drivers only support cards that use the GCN architecture, and the older cards are still considered unstable and not enabled by default (they'll still use the radeon driver). However, the last I checked amdgpu-pro wouldn't work in -current because that X.org is too new. However they've done a lot of improvements to the opensource drivers since the 4.4.x series, so it might be worth looking into newer kernels.

@Drakeo, unfortunately, that didn't make it into the 4.14 kernel and is in the 4.15 RCs right now. I heard of a tentative release sometime in January.

I was being silly, my actual GPU is completely different from the drivers I downloaded.

marking this one as solved, I'll be back with a more detailed post on some problems I've been experiencing

FWIW 4.15 kernel has 100 kloc+ of new AMD support. As new as your graphics card is I recommend you learn "make oldconfig" and build a 4.15 kern3l.
