aww shoot! Well I may have to reconsider the partition solution once again, it seems. I looked up the words 'opengl game, and found this game list: http://en.wikipedia.org/wiki/List_of_OpenGL_programs It says among other tings, that Portal 2 in the Mac-version i OpenGL: "Portal 2 (Mac OS X version) (upcoming)" Does this then mean, that if I would want to run Portal 2 on my Ubuntu computer, then I should buy the mac-version?! (And seriously, how weird is it, that it's the Mac version that's the most open-source?!) Btw - sorry for my newbieness, I am just hopelessly in love with the open-source concept, and so utterly tired of both Win and Mac - so I am just trying to learn about the alternative's possibilities.
