Linux faithful everywhere can rejoice, as Valve announced an internal beta of Steam for Linux starts next week, with a private external beta for 1,000 users in October. There were no specific dates mentioned for the external one, but it's welcome news either way.
The beta supports Ubuntu 12.04 and higher, and includes a copy of Left 4 Dead 2 to test. It'll be interesting to see L4D2's performance across multiple systems, especially since Valve tweaked the game to run faster in Linux than Windows. Additional games will not be included, nor will Big Picture mode, but the beta gives Valve a chance to show where it is with the Linux version. Any Linux user interested in trying to have a chance at the beta should read the following:
We will be using a sign up page for the external beta. Information about the sign up will be announced in a future post.
For those new to Linux, we recommend waiting for a subsequent release where more features are implemented along with improvements to the user install experience.
Keep it tuned for updates on how to get into the external beta and future improvements to Steam for Linux.
