So today i tried to install steam and after that KSP. When i opened KSP it got stuck to downloading screen, but the great thing is that i found solution which worked and now game runs smoothly. (Ubuntu 16.10)
How i did it?
1. In steam go to KSP properties (by right clicking KSP in steam library)--> Local files --> Browse local files (or you can go to KSP files with terminal also but this is easier)
2. Okay when your file manager opened, right click --> Open in terminal
3. run command: LC_ALL=C ./KSP.x86_64
4. KSP works
Only bad thing about this is you have to do that everytime you want to open KSP
Also i got problem with screensize and i couldn't see like 50pixels down... (i used gnome desktop)
But i found solution to it also.
I disabled top bar so i could (see) hit the apply button so i could change it to fullscreen it settings.
Took me like 1hour to find solution by googling...
Hope so this helps someone!
