Any ideas?

 

I am having the same issue. This is from Editor.log:

In both cases, it looks like Unity has failed to create a valid OpenGL context.
Do your environments support OpenGL 3.2 core profile?

 

Not

Not at the moment:

OpenGL vendor string: Intel Open Source Technology Center
OpenGL renderer string: Mesa DRI Intel(R) Ironlake Mobile
OpenGL version string: 2.1 Mesa 10.1.3
OpenGL shading language version string: 1.20
OpenGL extensions:

Would it make sense to downgrade Unity to a pre-5.5 version? The release note for 5.5 says "This means that your development environment must support OpenGL core profile 3.2 or later." .. I wonder if that's much more feasible than maybe upgrading my Linux Distro (I am using Ubuntu 14.04) just to find out that it still doesn't work.

 

It's up to you, of course.
I can say that the mesa drivers that come with Ubuntu 16.04+ do support OpenGL 3.3 core profile or later, provided that it believes the hardware is sufficient.
One consideration is that we're no longer updating Linux editor releases prior to 2017.0...

 

I made the upgrade to 16.04, but my GPU just doesn't support OpenGL > 2.1, if I understand the new, extended output from glxinfo right:

Extended renderer info (GLX_MESA_query_renderer):
Vendor: Intel Open Source Technology Center (0x8086)
Device: Mesa DRI Intel(R) Ironlake Mobile (0x46)
Version: 17.0.7
Accelerated: yes
Video memory: 1536MB
Unified memory: yes
Preferred profile: compat (0x2)
Max core profile version: 0.0
Max compat profile version: 2.1
Max GLES1 profile version: 1.1
Max GLES[23] profile version: 2.0

But I could finally start the Unity Editor setting LIBGL_ALWAYS_SOFTWARE=1 before running it. Must have to do with the newer Mesa installation since 16.04. I'll see how far I can get with software rendering.
