Just got KSP on Steam. v0.21.0.0 Running Kubuntu 12.04 (will upgrade soon). AMD Phenom, AMD 6950, prop drivers 13.4 Tried the recomended start up strings posted, every time I get top the launch screen with the message window "KSP Stats Tracking" and I cannot click on anything, tab or space or enter anything, the program just sit there with the music playing. Any thoughts on how to get past? --Edit-- Just found that my problem is the mouse focus, it is way off. Will do searches on that and see if I can correct. --Edit 2 -- Right, going full screen fixes the focus. KSP does not like being in window mode. Gone FS and having fun.
