Here is the latest instalment of Steam's Hardware Survey , as usual we do our monthly thing and compare it and talk about it and make sure you know not to use it as a hard figure.Ubuntu 13.04 64 bit 0.40% -0.03%Ubuntu 12.04.2 LTS 64 bit 0.15% -0.05%Ubuntu 13.04 0.12% -0.01%Linux 64 bit 0.10% 0.00%Linux Mint 15 Olivia 64 bit 0.08% -0.01%Ubuntu 12.04.2 LTS 0.08% -0.03%: 0.93%The Other category may contain a few of the smaller Linux distro's like Fedora, Gentoo and Arch for example.Other 0.67% -0.06%Especially when before the main stats did contain quite a few more Linux distro's it's safe to assume some of the % is Linux as well.There is this long bug report on Valve's github where a fair few users are stating they have never even seen the survey under Linux. I am one of them, yet I am logged in everyday.Just be aware these results will probably not be that accurate as we don't know how they do their percentage results, they could be rounding up, rounding down or truncating the percentages. So a 0.5% could actually be nearly 0.6% as it could be 0.59% but they could do no rounding and simply truncate it.Also it won't be every Steam user (it's anot a full statistic) so it can be as simple as not actually showing the survey to many Linux people. Let's face it we know they don't survey 100% of their user base, only a small fraction of it, so bear that in mind as well. Personally I am still yet to see it under Linux so it's not counting me that's for sure and I am logged in every day!Also to note is that Linux is apparently only sitting at around 1.28% of the worldwide desktop share anyway according to Net Applications. Their reporting should also be taken lightly too since it's all using web-based counters.Lastly Linux users typically shy away from any form of DRM, so you can bet there is a large bunch of Linux users who just simply refuse to use Steam.
