linux: VK_ERROR_INCOMPATIBLE_DRIVER error message should be more clear about potential solutions

The error is the same with other examples.
Strangely, at first build I had just a black frame with frame numbers in stderr.

Any idea how to correct this ?
Best !

[alichraghi]

your GPU is very old and doesn't support Vulkan API
but i wonder why we don't ignore gamemode errors (or maybe i just didn't find it) if not present in system
(https://www.intel.com/content/www/us/en/support/articles/000005524/graphics.html)

[emidoots]

The gamemode error is just a warning message, it's not the issue/cause here. Though I agree we should make that more silent / look less concerning.

Can you try running with MACH_GPU_BACKEND=opengl @samusz ?

[emidoots]

Filed #459 for silencing the gamemode warning.

[samusz]

Yes,
this is a very old personal laptop I use for simple dev task and experimenting...

Ah, that's annoying, sorry - I was hoping that would just work.

Can you try this, too?

Hmm, that's quite strange. It looks like it's still trying to use Vulkan. This could either be a bug in Mach, or you might have a slightly older version of Mach before I renamed the env var.

Try this just to be on the safe side:

export MESA_GL_VERSION_OVERRIDE=4.5
export MACH_GPU_BACKEND=opengl
export GPU_BACKEND=opengl

Then run:

zig build run-example-triangle

Does that work?

[samusz]

Nope, still fails somehow 😞

ps Sorry for the delay.

Here the output with the exports

@grav try to install vulkan drivers. e.g. on Arch linux i fixed this with pacman -Sy vulkan-intel
