Install amd-catalyst

Hello, i have problem with installing catalyst drivers. I have hd6870 and open-source drivers has no opengl4.1 for that graphics card. I tried to install with the wiki guide. I tried to install with this guide: https://www.youtube.com/watch?v=0P-mG8s8Deg&t=20s . Everytime i try I have black screen and blinking "_" on top left corner. I'm using zen kernel, kde and gdm. Some suggestion for newbie?

Which packages for AMD catalyst did you install?  Are you certain the ati and amdgpu drivers do not support your GPU?
What is the contents of the logs from lightdm and Xorg?

Re: Install amd-catalyst

That xorg log doesn't mention catalyst / fglrx at all.

[   564.554] Current Operating System: Linux kacper-pc 4.14.15-1-zen #1 ZEN SMP PREEMPT Tue Jan 23 21:49:22 UTC 2018 x86_64
[   564.554] Kernel command line: initrd=\initramfs-linux-zen.img root=PARTUUID=43c6133c-1902-416e-93e0-020b6fb27e55 rw

The packages in Vi0L0 catalyst repo are meant for arch stock kernel, for a custom kernel like zen you'll have to build your own version .

Re: Install amd-catalyst

I installed drivers but I have smaller problem now. I want to install lib32-catalyst-libgl but I can't.

"error: unresolvable package conflicts detected
error: failed to prepare transaction (conflicting dependencies)
:: lib32-catalyst-libgl and lib32-libglvnd are in conflict"

EDIT: I installed it with pacman -Sdd without conflicts. Interesting.

Re: Install amd-catalyst

Seriously, do not use catalyst, it is not supported since three years ago, and it forces you to put your arch install in a *unsupported* buggy and insecure state.

Bad idea.

Arch linux mesa packages switched to glvnd some time ago and catalyst doesn't support glvnd at all.
You need https://aur.archlinux.org/pkgbase/mesa-noglvnd/ and https://aur.archlinux.org/pkgbase/lib32-mesa-noglvnd/ .

While it's technically possible to run archlinux with catalyst, I agree with Mr.Elendig that's not  a good idea.

There may be alternatives using the modern opensource drivers though.
Many pre-GCN cards like yours support most of the openGL 4 extensions but only advertise OpenGL 3.3 because they lack fp64 support .
Very few applications use fp64 and you can override the opengl version reported by mesa.

Check https://www.mesa3d.org/envvars.html .
If you're more comfortable with  a gui to change those settings try adriconf or radeontop (both are in AUR) .

In the near future you may not need those tools anymore, as a few mesa developers (mostly D. Airlie) are working on providing software fp64 support so more cards can advertise OpenGL 4.x .
