Missing buttons, options and astronauts in Kerbal Space Program

Solution 1:

If removing/reinstalling the game ends in the same result, it's likely a bug on that platform. Go to the Squad website and submit a bug report, giving as much detail as possible, including screenshots, and your system information and steps you took to reproduce the problem.

You can also try to revert the version on Steam until a patch is released. I've not done this myself, but I hear of others doing it when game updates introduce unplayable bugs.

You might still try updating your graphics drivers too. If you play in 64-bit mode, try the normal 32-bit mode to see if you have the same issue. (I saw some weird behavior in the 64-bit version that I didn't see in 32 bit.)

Solution 2:

It's probably problem with compatibility with Unity 5. Try to read this: http://forum.kerbalspaceprogram.com/index.php?/topic/137849-ksp-does-not-show-any-menu-content/

Solution 3:

This is an issue with Unity's GUI functions and the Linux Mesa drivers.

To fix it, delete your config file, and then load KSP through the launcher,and use the nearest standard resolution

To give you an incomplete list of common valid resolutions: Widescreen: 1280x720 (i.e 720p) 1920x1080 (i.e. 1080p) Narrow Screen: 1024x768 (i.e. 768ni XGA/XVGA)

Known NOT to work: 1600x900 (i.e. 900p/HD900)

There are probably more resolutions that work, and if someone knows one that does, be sure to reply to my comment with it.
