Computer freezes when KSP finishes loading (But before it goes to the start screen) on Ubuntu Linux

[Ben J. Kerman]

When I start KSP (through Steam) on Ubuntu, it says "KSP.x86_64 is not responding" and gives me the option to wait or force quit, and when I click wait it shows the same thing a couple of times, and after I click wait a few more times, it (KSP) starts to load. It appears to work fine until it gets to about "Expansion Loading Complete" , then it freezes up. The clock stops, I can't move the cursor, and I can't click anything. and I need to restart the computer to unfreeze it.

What do I do? And has anyone had any problems with mods on Linux KSP?

I have no experience with Linux, but game freezes at "Expansion loading complete" are usually caused by exceptions when the game tries to compile. While it's more common for this to happen with mods installed, you can still get issues in an unmodded copy of KSP if it gets corrupted in some way or some files go missing, so best to check that your installation of KSP is OK or perhaps try reinstalling it fresh; either way backup your save games first!

It shouldn't completely lock up your system tbf - sounds like your system might be using  up all it's swap (or your swappiness is set too high) - I've seen this before but only in low memory situations. The OOM killer in the kernel does actually need a small amount of memory to work.

Try watching the results of

watch -n 1 free -h

See how much swap you have/KSP is using at the point of the freeze.
