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 right, I don’t have mint/ubuntu installed nor that kind of hardware (anymore), so I can’t give precise instructions. I was just like: see that you’re not missing any of these packages/repos/firmware and adapt it to your needs. I had to deal with a laptop with dual gpu (intel+amd) and it was such a pain in the ass to get it working. I think you needed to have n packages installed, add grub flags, configure X11 to use amdgpu and blacklist radeon and even when I had it working, the amd gpu was only compatible with a limited amount of vulkan instructions so I had graphical glitches and games breaking. Old dual gpu setups are just a nightmare.
