Arch is loading radeon driver instead of amdgpu for my R9 290

Hello all and thanks for your support!

I've recently installed Arch and I've figured out it loads radeon driver for my VGA. After that, I installed xf86-video-amdgpu package and blacklisted the radeon module, but it fails to load X server. In fact, even though amdgpu is correctly loaded, Arch insists to use radeon.

lsmod output (I de-blacklisted radeon module to have my PC correcly working):

can you blacklist radeon and show us xorg log when starting X fails w/ amdgpu?

Your card is a GCN 2 type. check https://wiki.archlinux.org/index.php/Xorg#AMD
It does show that default choice for your card is ati , NOT amdgpu .

If you do prefer to use amdgpu, you'll have to use a customized kernel, look up linux-cik from AUR.

Well, that sucks. My card is fully compatible: https://wiki.gentoo.org/wiki/Amdgpu#Feature_support
I'm not going to mess with a custom kernel since I'm completely new to Arch and I have my troubles big_smile anyway I think it's not fair. Let's see if Linux 4.9 will change something.
Thank you for your reply.

Re: Arch is loading radeon driver instead of amdgpu for my R9 290

The gentoo wikipage has a note for your chipset : 1 Support is optional in the kernel.

Kernel 4.9 will have experimental support for GCN 1 chipsets, but according to comments by Bridgman on phonoronix forums there are to many bugs with GCN 2 + amdgpu kernel module to enable support by default.

Re: Arch is loading radeon driver instead of amdgpu for my R9 290

Hey, I am trying to install the ATI driver for my R9 290,

is it just the packages: 

xf86-video-ati

and 

mesa-libgl

?

Also I installed amdgpu already before reading this post. Could I leave that installed and install the ATI driver ontop?

Srry for the noobness, thank you for the help

Re: Arch is loading radeon driver instead of amdgpu for my R9 290

tsangares: to avoid clutter of posts, forum ettiquette usually states you should make your own post. That being said, rule of thumb is to only have one driver installed and active at a time. I'm not an expert for AMD cards, but I believe from my brief research that those are conflicting open-source variants, with amdgpu supporting older cards and ati supporting newer ones (pretty much just the wiki page on this). You'll want to uninstall amdgpu if you're installing ati. Also, most of the information I'm referencing is coming from the wiki, here: https://wiki.archlinux.org/index.php/ATI. The wiki is very informative and complete, so it would make a good reference for some parts of system configuration (for instance, which driver you should start with/install), which can help clear up some confusion in the future.
