SteamOS and Wayland

[FrigoHat]

Actually, SteamOS use X as the default graphical server, and the Steam BigPicture mode is based on a compositor directly developed for X.
In October, Fedora will migrate to Wayland, the new graphical server designed to replace X, with the new release of the Linux distro, Fedora 21.
Various desktop environment, like GNOME (with the 3.14 release), KDE (with the 5 release), Mate, LXQt, E19 and others, will be natively compatible with Wayland, like its compositors, Mutter and KWin.
When will we can see a SteamOS release based on Wayland? This new graphical server is compatible with most of tools used in some Linux games, like SDL, PulseAudio or OpenGL 3.x/4.x.
Regard video drivers, Intel already has a version of its drivers available for Wayland, and NVIDIA has recently annunced that they're currently working on a Wayland version of its video driver. For AMD Radeon users, the open source Radeon driver is fully compatible with Wayland.
For the BigPicture session, Wayland provide a good compositor called Weston, that can be used for BigPicture. For the integrated WebKit web browser, Google created a system called Ozone-Wayland that allow the execution of Chromium/Chrome web browser (based also on WebKit) natively on Wayland.
In conclusion, I see no reason why SteamOS should not switch to Wayland.

SteamOS is based directly on Debian Stable. When Debian Stable adopts Wayland, SteamOS will follow.

Debian is "The Universal Operating System" it will have Wayland and Xorg for years to come

But SteamOS has various changes compared to vanilla's Debian Stable. And Wayland is included into Debian's repository :)

I'm with you Wayland has been in development for years and is looking fully ready to take on a job like SteamOS only if we had AMD making drivers for Wayland as Nvidia is soon to release it's Wayland Drivers? also Gnome 3.14 and Wayland 1.6 are releasing in September

Games and SteamOS not Wayland uses X.org or
Games use directly access OpenGL and the Kernel, x.org and wayland are used for windowing system (Gnome, KDE)
look at this chart that u will see:

this graph is on wikipedia, where you talk about MESA:

Do not worry or X.org with Wayland, SteamOS not need to use!

u guess you only looked at performance aspect, but there are loads of other reasons why it should use it. main reason is that xorg is barely supported lately and once wayland ships for real, it will only go to worse. more or less majority of previously xorg developers works on wayland. same thing will probably happen to libinput too. and most games should be supported by XWayland even if not updated or so i understand

wayland also has clean extension mechanism and some extensions that many gamers would love, for example presentation. not to mention this time around they are actually working with vendors like nvidia to find common path that would insure better binary drivers

also, once majority of distros will ship with wayland, it would be nice if steam kept as nice compatibility as it does.

i really suggest you watch this presentation from ex xorg developer

man, I'm talking about games that do not use wayland or x.org
Games do not need these libraries.

applications use these libraries because they use gnome or KDE, and games do not use gnome or KDE then it is not necessary to worry about wayland or x.org, games do not use this library

[Balderick]

that is why steamos uses mutter wm http://en.wikipedia.org/wiki/Mutter_(software)

ok, i guess you don't need things like controllers, sdl, sdl2... the middleware crap, you know? must be nice in your world, lol. same as multi display which is broken like... forever. and since more or less everyone went working on wayland, no one will fix it really. also, playing games with multiseat wouldn't hurt either. having screenrecorder that works and uses way less cpu... nah, who needs that

nice

You will be able to run wayland on SteamOS, but it will involve a lot of compiling and will not work as well. Steamcompmgr will not work on wayland. If you were to compile wayland/weston 1.5, mesa 10.2 and xwayland on SteamOS, you would be able to use that, but it won't be very good yet. Wayland support in sdl2 is still not complete or the default either.

OK i see a some of you don't understand how the graphics stack works in Linux also Xwayland has been reworked and the upcoming Xorgs have the base patches to make it run as Xwayland it's only a matter of time before Xorg is abandoned or just maintained for LT Linux's

heres some good info (a little bit dated) but yes it does 100% matter what tool kit's you're using and what display server you're using

Well i'm going to just put this here

"X.Org Foundation
Yesterday 3:11 AM

Wayland should become the next graphics server.

X's model was to offload graphics rendering to a powerful computer. Nowadays, any computer has enough computing power to draw their windows themselves.

Wayland brings a much-smaller codebase that provides rendering guarantees and is much more secure. DRI3 is as close as we are going to get to Wayland in the X world, I guess."

SteamOS 1.0 will use X.org.

Maybe Wayland will make sense (read: have proprietary NVIDIA/ATI support) in the future.

well, until there is proprietary driver support it wouldn't make any sense at all. that one is kinda obvious. nouveau for games = SIGH (at least for now)

lots of distros will probably wait for the same moment too. i think only fedora is jumping the gun since basis of fedora always was 100% open source. but, even fedora will still ship xorg as backup plan if needed
