I hope that all helps someone. :)
That certainly helped me - thanks!
RX470 card on Mint 18.1 Mate

I tried a few different kernels, some of which gave scary messages at boot ...
settled on 4.8.5
I still get one red item in dmesg:

Code: Select all

amdgpu 0000:01:00.0: Invalid PCI ROM header signature: expecting 0xaa55, got 0xffff
others get this too, I read, maybe just live with that one.

On the big plus side:
- amdgpu dirver is loaded and working nicely
- two monitors are seen and identified
- desktop spreads across both monitors - order can be changed, etc
- resolutions and refresh rates correctly set

in other words all is good here

ps I have no need for audio over hdmi so haven't checked that

Can you descripe the steps you took? I got the same card but I got troubles getting the opensource drivers to work. Proprietary drivers work though.

Have you installed a more recent kernel already?

Yes I had installed the same kernel you were using. But still I kept getting the error from Cinnamon that it was still in software rendering mode. The resolution was alright though.

The AMDGPU-Pro driver works fine though. But I am still curious how you manged to get the standard open source driver working.

OK, following those two links in an earlier post, the steps were (as far as I remember!):

- update all installed packages
- apt-add-repository ppa:paulo-miguel-dias/mesa
- apt update

- open Update Manager, make level 4 updates visible in Preferences
- install the packages xserver-xorg-video-amdgpu and mesa
- install the level 5 package linux-firmware

- nomodeset in grub not required

Hope it works

Thanks,

Had same problem, the advice here fixed it (I think).

/xehpuk

PS
I had already updated the kernel to 4.9 perhaps that saved me from the black screen part.

dchild above also got a black screen with the new kernel.
Adding nomodeset to grub fixed it for him.
Not sure how that helps, but you could try that?
dchild wrote: 4. Installed the 4.7.2 kernel. (got a blank screen when trying to boot)
5. Added nomodeset to the config line in grub. (I used grub-customizer).

After that, it booted properly, and correctly loaded the amdgpu drivers.

I am glad I found this today. Ive had my RX480 about 2weeks and a week has been spent trying to get my 2 monitors identified. I am sure others have gone through similar things.
I have only 1giant 77hz refresh rate 1920x1080 unknown display, at least i have that but both are mirrors, very disappointed but this gives me hope.
I was not able to get the xorg AMD, ati etc to load right or something. cant recall all the info in the logs i got when i tried those few times.
took me all day to even find this here
I will try it all but thanks in advance , i believe I can make it happen with the steps here
I just found the amdgpu 16.60 but like the xorg drivers for most of what i did with the 7950hd i replaced. not perfect but working, all i did was change to the 480 and all could get was 1 unknown display but both my monitors worked in mirror and was ready to give up and revert back to 17.3,
this should keep me busy for a bit.
I stopped upgrading the kernel at 4.4.59 though. 2 things to thank you here for-even if I mess it up-am still pretty new with Linux and newer with hardware changes..was seduced by how linux just worked with whatever hardware i started off with. this is the first upgrade/change in the worst case scenario with 18.1 i gather

hmm, upgrades are always risky! (with ANY OS or software)
go through the various steps slowly - should all work out well in the end!
my system has been running beautifully for many weeks now ...

I did exactly this above and the computer went black. it will not boot, the gpu flashes on and instant shut down. It will not even post.
I did nothing else but enter this into a terminal, plus the linux build is on an eSata connected hard drive for what that's worth. even disconnected nothing happens.I am afraid the gpu is fried and no clue how entering linux commands can make it happen. no other instructions but those above too.

Any change?
Does it start with the RX480 removed?
