I'm trying to get Godot 3 running on my Linux Mint (18.3) laptop (old-ish, doctor gave it to me when my old Mac Mini died and I was facing running an a home business on my cell phone). Its graphics card does support GLES2 (with drivers). I can run blender all the way up to version 2.79, where blender switches from GLES2 to GLES3 at 2.80. I can load Godot 3, but if I try to do anything, like running one of the sample projects (2D or 3D), nothing happens. But, when I exit, I see some popups that popped up under the screen saying that it couldn't find GLES2.
glxinfo reports the following about GLES2 on my graphics card/drivers:
OpenGL vendor string: Intel Open Source Technology Center
OpenGL renderer string: Mesa DRI Intel(R) Ironlake Mobile
OpenGL version string: 2.1 Mesa 18.0.5
OpenGL shading language version string: 1.20
Can anyone see anything there that explains why I can run one app (blender 2.79) that requires GLES2, but not Godot 3? I'd really love to be able to use Godot 3, especially after seeing some great tutorials (nice pace, clear and easy to understand vocal narrative, etc.) that make it look much simpler than my first impression.
