Need help with vulkan for AMD ryzen 7 5700G

I have now reinstalled :enos: . I don’t remember if I had vulkan for AMD installed on my old installation.

This is my CPU

  Info: 8-core model: AMD Ryzen 7 5700G with Radeon Graphics bits: 64
    type: MT MCP cache: L2: 4 MiB
  Speed (MHz): avg: 1649 min/max: 1400/4672 cores: 1: 1400 2: 1400 3: 2994
    4: 3800 5: 1400 6: 1400 7: 1400 8: 1400 9: 1400 10: 1400 11: 1400 12: 1400
    13: 1400 14: 1400 15: 1400 16: 1400

and this is the basic installation of the graphics driver

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


Thanks that helps much.

I am sure i dont have amdvlk installed. if, then I would have to see it with inxi -G, right?

gonna try that

so far everything is working. i only play supertuxkart sometimes, then i use gaiasky and stellarium a lot.

i think i will install vulkan with the dependencies you gave me

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.
