[The Linux compatibility thread!]

I get a crash when I enter the sphere of influence of the Mun while I have the Mun set as a target, or if I set the Mun as a target after I have entered its SOI; KSP 0.20.2

Here are some Player.log excerpts for each of these scenarios:

[The Linux compatibility thread!]

I'm having horrible lag any time Kerbals are on-screen (Main Menu, VAB, Kerbin camera things when attempting to fly) that renders the game unplayable under Linux, and I have no idea how to debug this; the game runs perfectly under Windows. I've tried launching with LC_ALL=C, using the open source AMD drivers (using which the game just black-screen'd), tried different desktop environments, etc - nothing seems to help.

Info:

* KSP 0.20.2

* hardinfo report

* KSP.log

* Player.log

Any ideas?

Edit: Derp, use drivers from fglrx-updates, not from fglrx; that fixes a lot of the lag, though the game still isn't on-par with Windows for performance.
