A quick grep seems to suggest it's the responsibility of each EGL platform to re-implement the environment check:
$ grep -r LIBGL_ALWAYS_SOFT src src/glx/glxext.c: glx_accel = (getenv("LIBGL_ALWAYS_SOFTWARE") == NULL); src/glx/apple/apple_visual.c: else if (getenv("LIBGL_ALWAYS_SOFTWARE") != NULL) { src/egl/drivers/dri2/platform_wayland.c: int hw_accel = (getenv("LIBGL_ALWAYS_SOFTWARE") == NULL); src/egl/drivers/dri2/platform_x11.c: int x11_dri2_accel = (getenv("LIBGL_ALWAYS_SOFTWARE") == NULL); -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to mesa in Ubuntu. https://bugs.launchpad.net/bugs/1543952 Title: Mir binaries ignore Mesa setting LIBGL_ALWAYS_SOFTWARE=1 and only ever try hardware acceleration Status in Mir: New Status in mesa package in Ubuntu: New Bug description: Mir binaries ignore Mesa setting LIBGL_ALWAYS_SOFTWARE=1 and only ever try hardware acceleration.
