Slackware 14.2-current + AMDGPU-pro = unable to startx

Hi!

I just bought a new rig, and wanted to use the AMD architecture. Hence my build is as following:

MB - Asus M4A89GTD (with BIOS)
CPU - AMD Phenom II
GPU - AMD Radeon RX 550
(Believe the other parts do not add to the trouble)

I have had Multilib configured in all my installations

First I installed Slackware 14.2 (stable) but when testing with some games all graphic processes landed on the CPU resulting me to conclude that Xorg couldn't use the GPU. From this I have figured that I need the AMD drivers to use my GPU.

But between the testing I have upgraded my system to running Slackware-current (kernel 4.9.45)

I have ran following script that I found on this forum:
https://github.com/mdcdr/slackbuilds...ter/amdgpu-pro

The modifications I have done to the script is:
- Changed version number to match the packet I downloaded from AMD.com in "fwdir.patch" and "kernel-4.10"
- Removed the first hunk (12 lines) from "kernel-4.4.patch"
- Removed line 116-118 to "amdgpu-pro.SlackBuild"

I have tried to install the drivers on both huge.s and generic. I still get the same result. When I run "startx" my screen turns completely black and get no response from neither keyboard nor mouse.

grep 'EE' /var/log/Xorg.0.log returns:

A kind person from reddit told me to check in the folder xorg.conf.d after files named "amd" but I can't find any problems here, but I don't know what to look for.

Either way here is my org.conf.d

I have since installed another dist on my machine with AMD-support to be able to use the GPU. But my wishes are to use Slackware 100%

Would it be better to update the SlackBuild script with v.4.9.45 if you have this and not remove any lines?

Can you also post more of your Xorg.0.log so we can see what leads up the problem?

Here is my Xorg.0.log

I tried 2 weeks ago Slackware current and a AMD RX550 card.
root@hjp2:~# lspci | grep 550
23:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Lexa PRO [Radeon RX 550] (rev c7)

When I tried it did not work with the 4.9.50 kernel. I have am now using the 4.13.4 and X works. Audio via displayport does not work but if I am correct that is work in progress. (4.15 maybe...).

You have some more input on these cards on the ArchLinux site:

You might also need to install a 4.10.+ kernel and install the AMD driver directly from their site:

Are you running 14.2 or -current? They are not the same thing. -current is a development tree that can cause frequent breakages and, AFAIK, amdgpu-pro doesn't support the xorg version included in -current (at least the last time I checked and updated my SlackBuilds for amdgpu-pro -- it is possible if any newer versions are out that they finally added support for newer xorg versions).

If you are running 14.2, you should be able to run amdgpu-pro, although, I haven't followed the development of mdcdr's script. I know my 17.10 amdgpu-pro script would build ok, but I don't have amdgpu-enabled hardware to verify it works properly. Based on posts on this forum, my previous versions did seem to work fine.

Out of curiosity, are you doing anything that requires amdgpu-pro? The open-source amdgpu driver is quite impressive on its own and is able to be the primary driver on many systems.
