KeymasterOkay, for those who own the AMD R9 270 and below, the “radeon” driver does not work with Vulkan. It seems that you have to use the “amdgpu” to get it to work. For me, I have 6 older computers that I have the AMD HD 7850 / R7 265 / R9 270 (1024SP) in so it had me a little stumped. I now have it working but I probably did a little overkill to get it to work. I may have to do some more testing and narrow it down. I guess that kind of happens for the newbs. To be honest, I think my first attempt to edit grub actually had me in a different file as it was blank.
First thing I did was reinstall PeppermintOS 10 Respin in order to get the fresh start. Second was to install Vulkan with the line at the very bottom.
sudo apt install libvulkan1 mesa-vulkan-drivers vulkan-utils sudo apt update sudo apt upgrade
I then edited grub. I did not edit the /etc/boot/grub but the /default.
sudo xed /etc/default/grub
This is the GRUB_ section that I now have.
GRUB_DEFAULT=0
GRUB_TIMEOUT_STYLE=hidden
GRUB_TIMEOUT=10
GRUB_DISTRIBUTOR=lsb_release -i -s 2> /dev/null || echo Debian
GRUB_CMDLINE_LINUX_DEFAULT=”quiet splash modprobe.blacklist=radeon radeon.cik_support=0 amdgpu.cik_support=1 radeon.si_support=0 amdgpu.si_support=1″
GRUB_CMDLINE_LINUX=””I then updated grub with the following:
sudo update-grub2 sudo update-grub
Reboot and viola…
lspci -k | grep -EA3 'VGA|3D|Display'
now renders the following:02:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Pitcairn PRO [Radeon HD 7850 / R7 265 / R9 270 1024SP]
Subsystem: XFX Pine Group Inc. Radeon R9 270 1024SP
Kernel driver in use: amdgpu
Kernel modules: radeon, amdgpuand I can use without an error
vulkaninfo | less
If “vulkaninfo” reports missing, make sure you run the following:
sudo apt install libvulkan1 mesa-vulkan-drivers vulkan-utils sudo apt update sudo apt upgrade
Now you need to add support for i386 applications and Vulkan:
sudo dpkg --add-architecture i386 sudo apt update && sudo apt upgrade sudo apt install libgl1-mesa-glx:i386 libgl1-mesa-dri:i386 sudo apt install mesa-vulkan-drivers mesa-vulkan-drivers:i386 sudo apt update && sudo apt upgrade
Lutris should not give you an i386 Vulkan support error when starting anymore.
My reference for getting this to working was https://askubuntu.com/questions/927601/i-think-im-using-radeon-instead-of-amdgpu-how-do-i-change
