think i might have found a solution to this problem. This sounds just like the problem i was having. I had no problems on Ubuntu here, until i moved the loading game from one monitor to the other. Suddenly dissapears, and could not be relaunched even after reboot. even an older install would not work, nor re downloading and reinstalling would even bring up the squad loading screen. complete nothing when clicking on the play button in the launcher or dclicking the program itself.
Now for what i did and you can do what you will with this info. In a folder .config/unity3d/squad/Kerbalspaceprogram there are some prefs files i sent them to hell and now it works:) YMMV
