Asalle commented 1 month ago

Environment

Architecture: arm64 Operation System: Ubuntu 22.04 (custom image for Xilinx) ubuntu-frame: 144-mir2.17.0, with hardcoded ARGB pixel format, see #3466 libmali in a custom graphics-core22 snap: https://github.com/Xilinx/mali-userspace-binaries/tree/xilinx_v2022.1 HDMI monitor connected for output: Samsung U28R550UQP (4K)

Steps to reproduce

~ sudo ubuntu-frame

RAOF:

Ah. I see a problem in the probing code, there. I think we accidentally rely on EGL_KHR_surfaceless_context being supported. So, during platform probing here we setup an EGL context. That calls into here, which doesn't create an EGLSurface, so when we call make_current it does so with the default EGL_NO_SURFACE.

Manually selecting the platform will bypass some of the checks that fail above. This might work (from a VT):

miral-app  --platform-display-libs mir:gbm-kms  --platform-rendering-libs mir:gbm-kms

(It is also possible to configure Frame with these options, but this is simpler to test.)
