I guess what I am not understanding is why people (on the Valve boards) would complain about it not working on anything other then what it claims to work on. I might be misinterpreting something, but the beta was intended for a specific version of Ubuntu. I don't know, maybe I am missing something, but I read the forums and people complain about having problems trying to use hardware and software that isn't supported by the beta...and I guess that just doesn't seem all that helpful in terms of the development process.
Don't misunderstand me, I get it...people want it to work on their preferred hardware and on their preferred flavor of Linux...but it makes sense to me that Valve would pick a particular direction, get it working on that...and then go from there. I mean, they don't have much choice...there are hell of a lot of options when it comes to the Linux platform and you can't develop for all of them at once.
