1.3.1 works fine, 1.4 can no longer run (Linux OpenGL minimum requirement?)

[MrVanx]

Hi All,

First for the required info:

• KSP Version: I'm running in Linux Mint 18.3 (64 bit), and the game is running via steam;
  • From BuildID.txt: 02077;
  • From readme.txt: 1.4.0;
• Detailed explanation of what happens:
  • I run the game and i get a VERY brief window which closes immediately, this is with both the 32 and 64 bit versions, reverting to v1.3.1Ican play no problem.
• No need for screenshots or save files as the game doesn't run
• Player.log:

• System specs: I run a Lenovo L512 laptop;
  • Chipset: core i5 430M;
  • Graphics: Integrated Intel HD (inex reports it as "Mesa DRI Intel(R) Ironlake Mobile");
  • RAM: 4GB;
  • HDD: 512GB SSD (Samsung Evo);
• Clean Install, no mods

 

Generally I assume my machine is too old now and cannot support the minimum level of OpenGL required for 1.4?? It works no problem on 1.3.1 which I can revert to in steam (for now atleast). Is there any way around this at all? I think it might work if I run Win7 but I prefer Linux really.

Is there anything I can do here or am I destined to run no later than 1.3.1 on this machine, it s shame as I was just getting into a decent career with it!

Cheers All.

I don't because your card only supports OpenGl 2.1 on any OS: https://en.wikipedia.org/wiki/List_of_Intel_graphics_processing_units#Fifth_generation

You could try to set the option UNSUPPORTED_LEGACY_SHADER_TERRAIN in the settings.cfg to True.

Tried that change just now and still shuts immediately, no change to the play.log file.

FYI it runs no problem in Win7 (yes 1.4), I assume its using DirectX instead of OpenGL. Saved in the process of MOR last night

Oh wow, I forgot that DirectX exists.

Is that some kind of delicious biscuit?
