New submitter oakgrove writes "Valve Software confirmed today in a new blog devoted specifically to Steam on Linux (called Steam'd Penguins) that for more than a year, a Steam client has been in the works for Ubuntu Linux 12.04. 'We've made good progress this year and now have the Steam client running on Ubuntu with all major features available. We're still giving attention and effort to minor features but it's a good experience at the moment. In the near future, we will be setting up an internal beta focusing on the auto-update experience and compatibility testing.' The blog post also says that a working port of Left 4 Dead 2 is currently playable, and that their goal is to bring performance in line with the Windows version."
