Ubuntu - GPU - AMDVLK - Select the AMDVLK Vulkan Driver
NOTE: The actual driver files, can be located in various directories.
Although /usr/share/vulkan/icd.d/ and /etc/vulkan/icd.d/ are the most commonly used paths, the Vulkan loader looks in all the following locations:
/etc/vulkan/icd.d /usr/local/etc/vulkan/icd.d /usr/local/share/vulkan/icd.d /usr/share/vulkan/icd.d $HOME/.local/share/vulkan/icd.d
Select the AMDVLK Vulkan Driver
export AMD_VULKAN_ICD=AMDVLK
NOTE: AMDVLK is the default, but may cause issues with Steam and other applications.
- RADV is often much better, faster and more up to date!
Select the Mesa RADV Vulkan Driver
export AMD_VULKAN_ICD=RADV
Reenable the ICD based loading approach
Alternatively to the above.
export DISABLE_LAYER_AMD_SWITCHABLE_GRAPHICS_1=1
NOTE: When DISABLE_LAYER_AMD_SWITCHABLE_GRAPHICS_1=1, you can choose your preferred Vulkan driver by setting the environment variable VK_ICD_FILENAMES.
- For example, running Steam with the RADV driver is done by:
VK_ICD_FILENAMES=/usr/share/vulkan/icd.d/radeon_icd.i686.json:/usr/share/vulkan/icd.d/radeon_icd.x86_64.json steam
- To avoid crashes with 32-bit games, it is possible to assign the 32-bit variant and the 64-bit variant to the environment variable.
