Can't get Vulkan to work with my R9 280x

Disclaimer: noob btw!

So I have an old R9 270x and i am trying to set up my video drivers so i have vulkan support

I am using manjaro

vulkaininfo gives following output:

what I have tried:

sudo pacman -S mesa lib32-mesa libva-mesa-driver lib32-libva-mesa-driver vulkan-icd-loader lib32-vulkan-icd-loader vulkan-radeon lib32-vulkan-radeon

i edited my /etc/default/grub with this:

GRUB_CMDLINE_LINUX_DEFAULT=“quiet splash modprobe.blacklist=radeon si_support=1 radeon.si_support=0 amdgpu.cik_support=1 radeon.cik_support=0”

then i did sudo grub-update

I get this Output:

lspci -nnk | grep -i vga -A3 | grep 'in use'

Kernel driver in use: amdgpu

also i did this


Section "Device"
Identifier "AMD"
Driver "amdgpu"

also this:

$ mhwd -l

was missing, but now vulkaninfo ist giving me this one at the beginning
ERROR: [Loader Message] Code 0 : /usr/lib32/ wrong ELF class: ELFCLASS32

may be you need to rebuild it as its outdated or something.

sudo pacman -Su amdvlk lib32-amdvlk
warning: amdvlk-2.84.0421.g1dd300a-1 is up to date -- reinstalling
warning: lib32-amdvlk-2.84.0421.g1dd300a-1 is up to date -- reinstalling

i think those packages need rebuild.
as its happened in the past that they did not work.
sorry cant help further as i dont know much about it.

how do I do that?

No, no, no. Stop. Please stop.

I know you're trying to help but your approach isn't systematic and does more damage than good. Please, please, stop and think before posting.

What makes you say Vulkan support is missing after following the steps you outlined?

I couldn't get Dota2 started before, but now i do. Probably because of the missing lib32-amdvlk?
And also because if the Errormessages from vulkaninfo
So I guess this is resolved now since Dota2 starts with vulkan!


Welcome to the forums :hugs:

Does vulkaninfo provide any other output? If it still works apart from that error message (caused by the 32-bit library not being 64-bit) then it can be ignored.

It creates this bloat of text, which I guess would be too long for a forumpost

Ah, that's it working properly. It's providing all sorts of information about the Vulkan implementation.

I'd say you're all set. :wink:
