Hrm, it gave me problems last night. Something I have running I think was causing some sort of issue with it, that the menu wasn't all there... big transparent gaps.

If it runs so slow, it's probably not worth all the trouble to get it working. The one and only Linux box I have I didn't even consider that. What gets me is even with my best machine this one HDRI scene I'm doing is taking forever. I don't think it'll be done in time for posting here as a Christmas card, at least not with HDRI enabled.
