is it mandatory to install the vulkan-radeon driver?
if i want to install vulkan is it sufficient to install vulkan-radeon and as i see on arch wiki still vulkan-tools for verification?
is it enough to reboot the computer after the installation or do I still have to enter vulkan somewhere?
Edit: I see on another thread just use sudo pacman -S vulkan-radeon lib32-vulkan-radeon and restart.
exactly, but the restart is only necessary if you had amdvlk installed before (which is bad)
optionally, sudo pacman -S vulkan-mesa-layers lib32-vulkan-mesa-layers - it adds some more compatibility layers but most stuff will run without it.
are only needed if you want to have minimal test tools for troubleshooting. If you can launch any other vulkan application, you won’t need those tools but they also don’t hurt.
only if you want to use vulkan - if you do, this is the best way to do it. At the moment, vulkan is only used by games as a default, some browsers can run on vulkan optionally, DE’s prepare for vulkan but none offers it yet
inxi doesn’t check or report vulkan drivers/versions, so no, you won’t see it, but it is also not installed by default.
you can check with pacman -Qs amdvlk if you have it installed. It might get installed when installing steam as it is the first entry in the list of vulkan-providers, but if you know what you do, you can also choose vulkan-radeon there.
