Linux build of game keeps crashing

Hi there! I am an indie developer at a small studio working on porting the windows version of our game onto Linux. Unfortunately, I do not have a lot of experience with Linux, and when the build I’m working on keeps crashing after launch I do not know exactly what is wrong.

Here are the specifications of my machine and operating system:
Computer:
Processor - 4x Intel(R) Core™ i5 CPU M 460 @2.53GHz
Memory - 3829 MB (940 MB used)
Operating System - Ubuntu 16.04.1 LTS

Display:
Resolution - 2390x768 pixels
OpenGL Renderer - Mesa DRI Intel(R) Ironlake Mobile
X11 Ventor - The X.Org Foundation

Attached is the Player.log crash information.

I think that my OpenGL drivers are up to date (when I tried to update them the intel integrated graphics updater said that they were up to date), so I do not know why my shaders are not compiling, among other problems in the build. If anyone can help me get a clue on where to start, that would be awesome.

It looks as though your gpu/drivers don’t support our OpenGL core renderer: “PlayerInitEngineGraphics: GPU not supported; OpenGL 3.2 is required.

You can force the legacy renderer on your machine by launching the player with -force-opengl , or you can make the legacy renderer the default in your player build settings.
