When launching Steam from the terminal steam start but there is a problem it say:
missing requested extension 'VK_KHR_surface'.
Vulkan missing requested extension 'VK_KHR_xlib_surface'.
BInit - Unable to initialize Vulkan!

64 bit games engine works
32 bit games engines don't

This happens using:
mesa-23.2.1-x86_64-1
mesa-compat32-23.2.1-x86_64-1compat32

llvm-17.0.2-x86_64-1
llvm-compat32-17.0.2-x86_64-1compat32
spirv-llvm-translator-17.0.0-x86_64-1
spirv-llvm-translator-compat32-17.0.0-x86_64-1compat32

vulkan-sdk-1.3.250.0-x86_64-1

i sent an issue to github steam-for-linux and they ask me for a Runtime Diagnostics i sent them that and the y told me:
the runtime Daignostic confirms that 32 bit Vulkan is indeed broken on your system because the Vulkan loader isn't finding a suitable driver for your video card, but beyond that it's not clear why that's the case.
This issue should be reported to your distro's package maintainer for mesa.

Could the problem be related to this? https://gitlab.freedesktop.org/mesa/...ac9885cc80b82f

if i rollback to:
llvm-16.0.6-x86_64-1.txz
llvm-compat32-16.0.6-x86_64-1compat32.txz

mesa-23.1.8-x86_64-2.txz
mesa-compat32-23.1.8-x86_64-1compat32.txz
spirv-llvm-translator-16.0.0-x86_64-2.txz

all games work fine.
what could be the problem?
Also im not able to build mesa 32 bits
it fail at [572/2561] Compiling C++ object src/compiler/glsl/libglsl.a.p/builtin_functions.cpp.o
ninja: build stopped: subcommand failed.
Mesa 64 bits build fine.

I've actually been having the same problem but with wine (and steam through wine as well). The problem for me occurs with all 32-bit windows programs that aren't shipped with wine (wine-shipped programs being whatever's in the i386-windows/ directory ending in .exe).

Like yourself, I've had to resort to the reverted packages.

How are you building the 32-bit mesa, and did you apply the patch in that gitlab link to it as well?

Hi TommyC7, Im having the same problem as you with wine with all 32 bit games too.
to build mesa 32 bit i use

. /etc/profile.d/32dev.sh and then
ARCH=i686 ./mesa.SlackBuild
and after that
convertpkg-compat32 -i /tmp/mesa-23.2.1-i686-1.txz
installpkg /tmp/mesa-compat32-23.2.1-x86_64-1compat32.txz

Problem is that mesa 32 bit fail to build so i can not test if the patch work or not.

Do you have a 32-bit installation of Slackware -current (VM or otherwise) where you can build it instead without relying on sourcing /etc/profile.d/32dev.sh?

Hi TommyC7, no i don't have a 32 bit installation of Slackware current, perhaps i could try with virtual box.

I built the 32-bit package but haven't been able to test it out yet. I've uploaded the original 32-bit version that I compiled on an up-to-date 32-bit Slackware -current machine and the compat32 version:

http://slackware.uk/~tommyc/2023-10-15/mesa/

Out of curiosity, how did you determine that patch to be the possible root cause of the issue (it's the only patch I added).

Hi TommyC7 i tested your mesa packages but it doesn't solve the problem, i didn't determine that the root cause could be solved with that patch it was just a thought.
Most likely the problem is related to llvm 17.
Anyway im seeing all kind of problems https://gitlab.freedesktop.org/mesa/mesa/-/issues/9932
