[Solved] Is it possible to start Linux Editor 5.6.2f1 in OpenGL 2.1 mode?

Is it possible to start Linux Editor 5.6.2f1in OpenGL 2.1 mode? It runs in 4.x by default now.

Story behind:
I upgraded Linux Unity Editor to version 5.6.2f1recently. It runs ok on my desktop, but it crashes (when I select and open a project) on my laptop. I couldn't find any information about the crash (Unity doesn't display the "report bug" window and I couldn't find any log file). I have theory that the problem is that my laptop is old and it's graphic card supports only OpenGL 2.1 which was used when I run Linux Editor 5.4.x.

I don't use my laptop as a main development station, of course, but I use it on travels for smaller coding tasks which doesn't require running main graphic-heavy scene, like game logic, unit tests and so on.

I actually wouldn't mind if "game" and "scene" tabs wouldn't work in the OpenGL 2.1 version, I just need to see if Unity compiles my code, access to unit testing tab and executing these tests.

 

No, you can't, but you can try using -force-glcore3x where x is some number to try to use opengl 3

 

No, it is not. Since Unity 5.5, OpenGL 3.2 core profile or later is required.

 

OK, thank you very much for your time to answer.
