Hi folks, I'm new to Linux but decided to try it with hopes of using KSP 64bit to run more mods without crashing. Using Ubuntu 14.10, I followed the great installation guide posted by Sal Vager. Unmodded, the game ran fine using both open source and proprietary AMD drivers. After installing mods using CKAN, I start the game (everything loads up very quickly), go into VAB, and usually, as soon as I get the first part out (for example MK1 cockpit), the game freezes. Music still playing, no keyboard control, and sometimes mouse still usable, but I cannot go back to the desktop environment to kill the KSP process - so I'm forced to reset the computer. Uninstalling the part heavy mods doesn't seem to change anything. I tried uninstalling mods thinking it was a memory problem (I have 8GB). System Monitor crashes as soon as KSP starts, so I used the TOP command to track memory. Right up until the point KSP freezes, only ~3.1GB RAM used by KSP, and CPU is running at 101.4% somehow. I am including the KSP.log fileand player.log file: https://drive.google.com/file/d/0B4gbbRcUMvBacDdFZ1RGOGdpdEk/view?usp=sharing https://drive.google.com/file/d/0B4gbbRcUMvBaVU43dEc4Q0hrSm8/view?usp=sharing I apologize if someone has already answered this - I looked everywhere on the forums without luck. Thank you very much for your help everyone!
