Im at a stump... I have tried all linux bases (debian, arch, red hat) and both super new kernels and super old kernels, but my R9 Fury refuses to work properly.
I have also tried using all the propietry drivers available in the kernel, all the open source and the propietary driver available on AMDs website.
Heres whats happening:
It seems that the GPU isnt being used. I get extreme lag, when running top I see that X server is using between 40 - 120 % cpu on idle!
When I try installing the AMD driver from their site, X server just refuses to even start DERP
Im kinda at the end of my linux knowlege (serves me right for being a sysadmin and knowing nothing about this GUI thing)
It has been a while since I have had a "new" and card. but I recall having to use Svn/git version of drivers including dri and Mesa drivers to get my card to work. have you tried any live drivers ?
I may be wrong as far as I was aware proper functionality with the brand new cards was only possible with amdgpu. The open part has only just hit the kernel.
Full functionality coming 2089 if AMD keep up the pace :/
The R9 fury just doesn't work right in Linux. It is so bad I bought a 390 instead. The best thing to do would be run a rolling release distribution and stick with the open source drivers for right now.
Fedora + fedora rawhide kernel (Google it) will give you the latest kernel. Unfortunately it is a case of waiting. I have a thread about this just the other week.
They essentially abandoned the not so great but kinda worked fglrx drivers but didn't release the amdgpu drivers so now all is AMD customers are stuck in limbo while we wait.
The open drivers (radeon) are pretty decent but I've been having issues with them recently that's pushed me away from AMD.
And if you have there latest cards well your basically out of luck untill somthing hits mainline which to be honest I expect at the end of the year before we see anything working well.
I ended up buying a nvidia card, as much as I love AMD and their commitment to open drivers, there taking there time delivering and losing customers, even if it is a small number.
In comparison I enabled the alternative nvidia repo for feodra, installed nvidia-drivers (installed the kernel headers first forgot that) and it just works well.
Yeah j had similar graphical issues but.. Different. Single screen wouldn't work with AMD card (super glitchy) (this wasn't just fedora) dual screen worked fine. I gave up on AMD for now.
If they get their work don't and release the stuff it would be great. I think they should just go here's all the documentation and money, go make. Would be done faster.
Hence my sadness. I'll gladly move back once there at a working point. They defiantly want to go this route. Seems the transition is a bit to be desired.
