Note

Here's a historical look at the Linux market share on Steam, gathered using Valve's publicly provided data. Be sure to look over all the information, don't just take the first chart. If you have feedback, let us know in this feedback Forum : Data from before September 2018 has been removed, due to a flaw Valve reported in the survey. Windows 7 machines were being over-counted since around August 2017, so there's no point keeping false data. See here for info . Then, Valve also reported another flaw in October, where smaller distributions were not being counted and the data for September was updated.
