[Desktop-packages] [Bug 1543952] Re: Mir binaries ignore Mesa setting LIBGL_ALWAYS_SOFTWARE=1 and only ever try hardware acceleration

2016-04-27 Thread Daniel van Vugt 
Accidentally found a workaround!

You can set environment GBM_ALWAYS_SOFTWARE=1 for Mir servers and
clients, and they will then successfully render in software using
LLVMpipe.

2016-04-27 Thread Daniel van Vugt 
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);
