Valve has announced that a beta for Steam on Linux will begin in October. According to a blog post on Valve’s site, internal beta testing will begin next week, followed by a private external beta for 1,000 users later in October.

The private beta will include Steam and one Valve game and will support Ubuntu 12.04 and above. It will not yet include Big Picture Mode or additional Valve games. “For existing Linux users, the external private beta is a good release for seeing where we are in running our games on Linux,” the post notes.
