mega_newblar's advice led me to the solution, set FULLSCREEN = True. This feels like a bug. I'm going to submit it. Thanks everyone for the help!

Yep restarted (few times actually). Note I was always using the 346, just from a different repo before. I'm not using Bumblebee. I set the graphics card to discrete in the BIOS on startup to avoid the complications optimus can cause.

I've been trying KSP.x86_64, although I did for kicks try the 32 bit version with the same result. Here is my KSP log: http://hastebin.com/zenoderezi.vbs Also note my driver is 346.59 from nvidia-346 the recommended proprietary driver.

Hi sal_vager. I am using the 346 driver as you suggest.

Behavior is as follows: Start from the command line or launcher. Screen goes black. Screen returns to desktop with normal KSP loading screen in window. Mouse moves but the loading screen does not change. Music starts. Computer is totally unresponsive besides mouse moving. Cannot alt-tab or change workspaces. Eventually can get to virtual terminal to shutdown but this takes some time. KSP version is: 1.0.2.0 From the Players.log log we have: The referenced script on this Behaviour is missing! (many times) Serialization depth limit exceeded at 'ThermalLink'. (many times alternating with the following) Serialization depth limit exceeded at 'OcclusionData'. I previously ran KSP on ubuntu 12 without issues on this machine. Any ideas?
