I’m trying to run Godot 4 with the Forward+ Renderer on an older Thinkpad (T420 i5 2520M). So far I’ve installed vulkan-intel, lavapipe (vulkan-swrast) and vulkan-ultis for vulkaninfo. Now I don’t get the “missing drivers” errors anymore, but now it just crashes. The console output is this:
handle_crash: Program crashed with signal 11
Engine version: Godot Engine v4.2.dev3.official (013e8e3afb982d4b230f0039b6dc248b48794ab9)
Dumping the backtrace. Please include this when reporting the bug to the project developer.

Is vulkan just not supported for older intel CPUs, or am I doing something wrong?
Maybe try installing swiftshader?
I actually did that before, but that ended up breaking a bunch of stuff. When running
vulkaninfo
for example, it gives me this output:/home/smorty/.cache/yay/swiftshader-git/src/SwiftShader/src/WSI/VkSurfaceKHR.cpp:246 WARNING: UNSUPPORTED: pSurfaceCapabilities->pNext sType = 1000111000 /home/smorty/.cache/yay/swiftshader-git/src/SwiftShader/src/WSI/VkSurfaceKHR.cpp:246 WARNING: UNSUPPORTED: pSurfaceCapabilities->pNext sType = 1000239000 Speicherzugriffsfehler (Speicherabzug geschrieben) (that's german for "save access denied, memory dump written")
So yeah, that seems to not work unfortunately.Oof, sorry. :( I had hoped that they sorted it out by then…
I’m a little bit confused? What would Vulkan have to do with the CPU? Isn’t the GPU the important part here?
It’s the iGPU. So I’m using the built in GPU in the i5.
“Please include this when reporting the bug to the project developer.”
So just search if there is already an issue on GitHub (e. g. https://github.com/godotengine/godot/issues/70506#issuecomment-1368316996 ) and file a bug report otherwise.
Maybe try previous stable 4.1.1 release.
