RX 4XX: Getting AMDGPU to work in Manjaro Linux

RX460 Woes

I finally found a solution to getting my RX460 to work in Manjaro. Since I did something a little different, I am recording it here for myself and anybody else who finds this post.

While this is written using Manjaro, it should work with Arch and other distributions (some files might be in a different location, though). It should also work with any supported card.

I use nano to edit the files below. Use whatever you are most comfortable with, but remember to run it with sudo.

The Process

After this, run:

Then edit /etc/modprobe.d/radeon_blacklist.conf (it might create a new file) and add:

Next, inside of /etc/X11/xorg.conf.d/90-mhwd.conf, delete everything in the file and add:2)Confession: I didn’t empty out 90-mhwd.conf.

I then restarted. This let me boot into the latest linux kernel (4.10.0-1-MANJARO) with amdgpu support!

I hope this helps others!
