Ubuntu 16.04 Intel Graphics: Unity, Xfce, KDE, LXDE, GNOME, MATE, Openbox

[i.prates]

First of all: I'm sorry if I'm mistaken about the section to post this question and I'll gladly fix it in case I'm wrong. Now to the issue itself:
I've been testing, for some time, a few Linux distributions (including Ubuntu 16.04). One of those test profiles (qgears2 - Text) yields results way below average for Ubuntu when compared to other distributions. I'd like to know whether those results are natural or, in some way, configuration dependent. What follows is the system under test configuration (all other test were executed in the same machine):

Phoronix Test Suite 6.6.1

I've read this whole thread and can't see an answer to this: Can someone explain HOW Unity beats Openbox? Given that Openbox won't even be using a compositor?

[varikonniemi]

Taking into consideration how many dislike unity, it is funny to see it as the overall winner.

You are confusing the "Suspend compositor for full screen windows" option with manually temporarily disabling compositor with ctrl+shift+F12. The latter is the suggested way by kwin's developer and the one you should use when playing games (of course, it works with Intel).

This is all automated testing, Michael rarely takes the time to tune things by hand.

Edit: I personally think that the real solution would be implementing _NET_WM_BYPASS_COMPOSITOR but Martin doesn't care so I fear we will never see it.

And then you get one game that doesn't use _NET_WM_BYPASS_COMPOSITOR and go back to complaining that KDE should do something about it.
Of course, we could get both features, but since developers won't implement both, I'd rather have the manual disabling of the compositor.

Each of the desktops was tested out-of-the-box. Plus with Intel anyways, doesn't that option on KDE not have any effect? They had disabled it in the code for Intel to have no effect, or did they end up reverting that decision?

As far I read and remember, automatic undirected composition for full screen window is not working and disabled. But Ctrl+Shift+F12 disable composition manually. It squeeze out some fps. In Dota2 or Team Fortress it is no factor for me(already vblank 60fps) but I have seen improvement in Shadow of Mordor or Metro redux with it.

Can we see Lumina DE results on Ubuntu?

It's too bad you didn't have a chance to test the SteamOS compositor in Ubuntu from the https://launchpad.net/~mdeslaur/+archive/ubuntu/steamos PPA,

Would it be tough to get something like this going with your Phoronix test suite. Ya know, with SteamOS being a big picture mode interface.

Would like to see some Solus benchmarks, they boast pretty loudly about their desktop performance optimizations, would be nice to see if they live up to it.

Not related to performance, but does Solus support FDE (encrypted root) at install time yet? If not, is there any plans to do so with 1.2 or any future release?

So knowing that pb of x11, and that you tested intel graphics... Can't you do another round with unity8 and gnome+wayland?
