Mir 0.0.9 Display Server Fixes Lag, VT Switching

He was stating that Steam would not be supporting Mir, I want to see some citations based on that accusation.

Read what you quoted. It says they have no reason to, and that's true.

[intellivision]

It's not FUD. Everything he said is true, and there are several articles on Phoronix that support his claims. Games are supposed to work out of the box with XMir/XWayland, so it's true that there's nothing mandating any port. However, I think native support would imply a slight performance win and would be cleaner, since that's one of the reasons to drop X; using SDL should do the work to avoid XWayland/XMir anyway.
And 13.10 will be XMir, and 14.04 too, according to Canonical. So, not FUD at all.

Do you have any citations for these claims or are you just spreading poorly written FUD as usual?

there is 100% no point in Valve supporting Mir at all or even Wayland as games will run fine on Xwayland once it gets fully coded

Ubuntu 13.10 will be Xmir not Mir

Fixed. 14.04 just drops pure X.org as fallback, but keeps using XMir.

Oh, right, thanks.

You mean compositing bypassing, don't you?

Yes.

[mrugiero]

If they are going with Mir in 13.10, what of the much-hyped Ubuntu/Valve union? Will Steam gamers have to swap Mir out for xorg if they are running 13.10 or later or will Valve only support 12.04 to 13.04 until Mir gets binary drivers for the green and red teams GPUs?

I only used one Steam game on Ubuntu, Portal, but it works OK with R600g. Anyway, I would rather use directly X.org instead of XMir.

No, they won't be using Mir in 13.10, they'll use XMir, which is the same X.org, just also with an additional layer on it. They'll use Mir only in 14.10 once it gets the ability to actually run something.

Not really. They're working on minor things, marketing them as major advancements. They still don't have the fullscreen optimisations they were talking about for quite a while now...

The fallback is actually a "feature" in LightDM. It'll work on any distro that has Mir. If unity-system-compositor decides to crash or fail in some way, LightDM will automatically spawn Xorg. Unfortunately, this doesn't always work properly and sometimes LightDM ends up crashing too.

EDIT: That's how the proprietary drivers are handled; crash unity-system-compositor and launch Xorg.

Yes, but it needs to be installed, and it won't by default in 14.04.

You can't argue with facts.

Hearing that from a person that refuses to back up any of his claims with facts is quite ironic, don't you think?

[chenxiaolong]

To be fair, Wayland hasn't gotten much further by that score. The best we have so far are nVidia working on EGL drivers, which would work for both (in theory).



13.10 has an Xorg fallback, so the binary drivers will be fine for that. It's getting taken out in 14.04, though.

It would seem Canonical are gung-ho to have 13.10 use Mir instead of xorg but as far as I know neither AMD/ATi nor NV have yet to even so much as mention Mir support, hence its questionable if 13.10 would be of any real use to anyone interested in gaming or video production.

They'll use Mir only in 14.04 once it gets the ability to actually run something. As for Steam, they will keep supporting X.org, because all the games run on X.org and will continue doing so for a while.

I admit i havent been kepping track of any of them, but reading the titles and looking from afar, i also have the feeling that mir is progressing quite fast.

You can't argue with facts. Mir development speed is phenomenal. And since Ubuntu is the only viable Linux distro of course I want to see them winning.

I'll still stick with wayland all the way, though. I dont like ubuntu's idea and they dont seem to be changing it any time soon.
