    So much for using it on a laptop with switchable graphics

    Of course of course, I know, not meant for that kind of device, but still.

      Hm I wonder why they didn't use compton as a starting point instead of xcompmgr... Compton is much improved with tons of bugs fixed.

        Did anybody tried to install these kernel on ubuntu?

          I'm happy to see that it's a very conservative distro pretty much based on Debian. That means games designed for SteamOS will most likely work with almost any distro out there. I was afraid it'd be too much like Ubuntu. With the direction Ubuntu is going I mean...

            anybody using a PREEMPT_RT_FULL kernel in Ubuntu is using something similar <minus, not having Aufs support, although, as SteamOS' kernel patches show, it works fine with RT, although i thought i spotted some fix for preempt_rt for aufs specifically....>.

            @Michael: to clarify, since you are quoting me in this article. On closer inspection the 282 ../rt/all (sub-folder) patches, are largely (but not all, afaict) in linux-rt patchset - I haven't run a diff, just from browsing. (and no point in making a diff, since i would still need to recognize functions, etc - that would be spread out between patches i am not necessarily familiar with.. although, i am curious about a few bits that might make nvidia more rt friendly.)

              I still don't see the newsworthiness of SteamOS.

              So it's a Linux distribution that is utilizes a Debian Wheezy base with extensive modifications. That's no different with Microsoft using a modified Windows for the Xbox. Or Sony using modified FreeBSDs for the PlayStations.

                It's different for several reasons. The most basic one, their modifications are open source. Then, the most important one for non-SteamOS users, their changes doesn't break compatibility.

                  Rt? This is realtime kernel right? Why did they use an realtime kernel for a game console system?

                    Coreboot?

                    I know it's not actually SteamOS related but does anybody have a hint if these Steam-Boxes (though it is more a design principle that can be used by many builders) are going to support / make use of coreboot? (And thus avoid UEFI crap)

                      Honestly, what's the point in using Coreboot over UEFI aside from ideological reasons? The latter is standard in off-the-shelf motherboards (remember, they want Steam Box to be "just a computer"), it's supported well enough by Linux and the boot firmware is largely an irrelevant concern. For secure boot, they'll either disable it or preload the SteamOS bootloader's keys into the firmware.

                        which leaves me wonder what did you expect.

                        it's a RT kernel distro with steam preinstalled and integrated to remove every bit of lag from games. the fact that i see desktop is bothering me more, especially since they use RT. hope it only runs when you leave out and logs out when you go back to BPM in order to conserve resources. i'd truthfully prefer something like Boxes integrated in steam and access remote machine, but hey... can't have everything. then again... when you think, having console and development seemingly integrated might be downright game developers tastes.

                          IIRC UEFI requires you to get a signature from Microsoft. That alone invalidates UEFI in my eyes.

                            I'm guessing to guarantee the responsiveness of the UI regardless of what background tasks are running. So there shouldn't be any stutter even if the OS is doing heavy background tasks like running the automatic update for example. Real time kernels are ideal for game consoles.

                              That's negative...

                              UEFI have nothing to do with signatures.

                              SECURE BOOT (which is JUST an extension to UEFI), does not either...


                              Its just OEM's who may not bother to add any non-MS keys... (That's why getting keys from MS is so smart)
