What is the proper way to install Vulkan drivers in Linux Mint 21.3 with an AMD GPU? (I think this issue is solved)
Edit: I think I've figured it out, it seems like Linux Mint defaulted to the wrong Kernel driver and I was able to switch it to the correct one.
I've already tried searching for this online but there is a reason I'm posting about it here. The last time I tried to install Vulkan drivers in Linux Mint, there was an update to the oibaf PPA that completely broke my Linux Mint installation and I had to manually reinstall it. I've read that, at least in the past, the oibaf PPA causes problems in Ubuntu but I can't find another solution to installing Vulkan drivers in Linux Mint. Is that the only way to install the Vulkan Drivers in Linux Mint, or is there another way?
Also, yes, Vulkan works in Windows and it did work in my previous installation of Linux.
You're viewing a single thread.
Could you post the output of
vulkaninfoincluding any errors that it might also print.If it's not shown, what GPU do you have?
Also run
lspci -k, is your GPU using amdgpu or the old radeon driver?My computer has an AMD Radeon R2 Graphics. It seems like both the radeon and the amdgpu modules are installed but the kernel driver in use is radeon. I'd show the output of "vulkaninfo" but it doesn't seem to show the full thing, is there a way I can get it to show the full output?
Cool, you're going to have to enable Sea Islands (CIK) support for amdgpu. You should just have to add
radeon.cik_support=0 amdgpu.cik_support=1to your kernel parameters. You're probably using GRUB so to do that you'll need to runsudo nano /etc/default/grubto edit it's config file, then add the above to the end ofGRUB_CMDLINE_LINUX_DEFAULT(keep it in the quotes, but space seperated from the previous parameter). Then reboot and hopefully Vulkan works!Alternatively, there's a section on the Arch Wiki for this, it should work fine for Mint too: https://wiki.archlinux.org/title/AMDGPU
Did I do it correctly?
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash radeon.cik_support=0 amdgpu.cik_support=1"After saving, is there anything else I have to do it get it to work?Oh whoops yeah there is, run
sudo update-grub.But otherwise that config looks correct.
Ok, do I need to restart my computer now?
Yep!
Ok, it seems to have worked as the game I was using for testing seems to be working fine.
Although, I keep getting the error message
(WARNING: radv is not a conformant Vulkan implementation, testing use only.), is that to be expected?Epic!
I've never seen that on modern AMD stuff that uses radv, but I'm sure it's probably fine.
Did you manage?
Yeah it seems like it's working now.
