Failed to initialize unity graphics

Good day linux folks!

Have just installed Unity through installer (2017.3.0b1), all dependencies add recommended packages.
Editor is to be opened OK, but when I try to open a project the error appears.

I’ve seen several threads about the same error for Windows: all of them are connected with DirectX issues (aren’t them?).

Have Ubuntu 16.04
OpenGL is OK (?)

OpenGL vendor string:   Intel Open Source Technology Center
OpenGL renderer string: Mesa DRI Intel(R) Ironlake Mobile
OpenGL version string:  2.1 Mesa 11.2.0

Not software rendered:    yes
Not blacklisted:          yes
GLX fbconfig:             yes
GLX texture from pixmap:  yes
GL npot or rect textures: yes
GL vertex program:        yes
GL fragment program:      yes
GL vertex buffer object:  yes
GL framebuffer object:    yes
GL version is 1.4+:       yes

Unity 3D supported:       yes

Running Unity with -force-opengl or -force-driver-type-warp flags does not bring results.

Have any ideas, what is the reason for the error?
Thanks

Hello.

Solved!

The problem was in the bumblebee, which was inherited from the previous version of the distro. But the bumblebee is not much compatible with the original Ubuntu 16.04, so I had to switch it to Nvidia Prime to support Nvidia OPTIMUS and to be able to use my Nvidia video processor.
Also, a proprietary nvidia driver was installed.
