64 bit - Running vulkaninfo returns error: vulkaninfo.h:477: failed with ERROR_INITIALIZATION_FAILED

Question

I? trying to get vulkan to work but I get the following error:

vulkaninfo
ERROR: [Loader Message] Code 0 : /usr/lib/i386-linux-gnu/libvulkan_radeon.so: wrong ELF class: ELFCLASS32
ERROR: [Loader Message] Code 0 : /usr/lib/i386-linux-gnu/libvulkan_intel.so: wrong ELF class: ELFCLASS32
/build/vulkan-tools-KEbD_A/vulkan-tools-1.2.131.1+dfsg1/vulkaninfo/vulkaninfo.h:477: failed with ERROR_INITIALIZATION_FAILED

Following command dumps:

lspci -nnk | grep -iA2 vga
00:02.0 VGA compatible controller [0300]: Intel Corporation Core Processor Integrated Graphics Controller [8086:0046] (rev 02)
    Subsystem: Dell Core Processor Integrated Graphics Controller [1028:0410]
    Kernel driver in use: i915

I have added the following to my grub config and initialized it

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash amdgpu.si_support=1 radeon.si_support=0 amdgpu.cik_support=1 radeon.cik_support=0"

followed by a reboot. The result is the same error :(

what am I doing wrong, can anyone help me?

Before I forget I installed vukan and mesa vulkan drivers and am running Ubuntu 20.04 LTS on a Dell Latitude E4310. Please help, I just want to play some windows (directX11) games with Wine.

This kind of cryptic error message can happen because vulkaninfo doesn't find any supported GPU.

It is likely that your GPU is not supported by Vulkan (too old), and so you won't be able to use DXVK (DirectX to Vulkan). You still may be able to run games without Vulkan by forcing Wine to use WineD3D (DirectX to OpenGl) instead. See Xaero_Vincent's answer in this reddit thread:

In Lutris you can easily disable DXVK as a option and on steam you can force OpenGL-based WineD3D:

PROTON_USE_WINED3D=1 %command%

You'll notice though that DirectX 10/11 games will generally run slower under OpenGL and some games will likely have graphics artifacts, since DXVK is more mature and further developed.
