I hit this all the time when trying to create a gbm device with nvidia and nvidia-utils installed on my arch laptop.

Seems like glxtest fails with:

glxtest: VA-API test failed: failed to initialise VAAPI connection.

But we still try to use dmabuf and crash somehow?

I think we try to use the intel GPU but try to load the nvidia GBM device, which causes things to go boom.

Well, WebGL?

Comment 3

[Martin Stránský [:stransky] (ni? me)]

We can't create GBM device on NVIDIA, we use EGL_MESA_image_dma_buf_export to get dmabuf surface from EGL texture.
And yes, dmabuf is used for WebGL.

I think we should add this test to glxtest to avoid Firefox itself crash.

This crash comes from broken systems, looks like there are some leftovers from old NVIDIA drivers while system is running on Intel.
Mesa (Intel) drivers (/usr/src/debug/mesa/mesa-22.3.5/src/gbm/main/backend.c:101) calls NvRmShimImportMemContextFromFd() from libnvidia-allocator.so.1.

No idea why libnvidia-allocator.so.1 is installed on the system.
