Recently I installed ArchLinux on an older computer. That computer had an Radeon HD7950 graphics card.
As I finished the install of ArchLinux with GNOME, I were not able to
start a Wayland session. It turned out that I were using the
driver which is not able to run Wayland. Additionally it was impossible
to get Vulkan running on this driver.
There is another driver for this graphics card named
this driver it is possible to get Wayland and Vulkan running on this
I struggled a little bit to get this running, so I wanted to document here what to do to get it working. At this point I assume you have a running ArchLinux install with GNOME.
First install the packages with
pacman -S mesa xf86-video-amdgpu amdvlk. Then it is important that the
amdgpu driver is loaded
radeon driver. For that write
in the file
Then Southern Islands (si) support needs to be enabled in the driver.
This can be done with writing the following in
/etc/modprobe.d/amdgpu.conf options amdgpu si_support=1 options amdgpu cik_support=0
options radeon si_support=0 options radeon cik_support=0
At last make sure that
modconf is in the
HOOKS array in
/etc/mkinitcpio.conf. Then regenerate initramfs and everything is
done and should work.
