[FFe] Regression: wrong window decorator applied

[Fred]

The gtk-window-decorator needs updating to GTK+3.

Support for Metacity theme support in Compiz was removed earlier in the Ubuntu 14.10 development cycle until deprecated function from GTK+2 could be replaced. This has been done and a feature freeze exception is requested to re-enable Metacity support once again.

The Gnome fallback session with Compiz is not generally usable without this support.

Tested with Ubuntu and Gnome fallback sessions. Please see the build log and changelog at https://launchpad.net/~ci-train-ppa-service/+archive/ubuntu/landing-016/+packages for review.

-- original bug description --

Windows have the wrong window decorator theme.
This can be seen when using Compiz in the GNOME Flashback session (package: gnome-session-flashback).

It does not respect the setting of 'gsettings get org.gnome.desktop.wm.preferences theme'.This is a regression.

This worked fine in Compiz 1:0.9.11.1+14.04.20140701-0ubuntu1 but is broken in 1:0.9.12+14.10.20140812-0ubuntu1 on 12 August.
Perhaps due to the change by Alberts Muktupāvels?
 * Remove gconf from gtk-window-decorator.

[Alberts Muktupāvels (muktupavels)]

This is because of new metacity release. Metacity theme support is now dissabled and will be re-enabled only when gtk-window-decorator will be ported to GTK+ 3.

[Fred (eldmannen+launchpad)]

I see.

Why is Metacity theme support disabled?
Is it possible to re-enable it again?
Are there any good reason why it is disabled?

Is anyone working on porting gtk-window-decorator to GTK+ 3? How is the progress going?
Will this be fixed before Utopic gets released?

What choices and alternatives do I have?
I can use Metacity then it works, but Compiz doens't work. Metacity isn't as cool, it has no animations.
I installed Mutter, but it has broken window decorator too, just like Compiz.

[Fred (eldmannen+launchpad)]

Actually window decorations work in Mutter, but only after copy my theme from ~/.themes/ to /usr/share/themes/.
Although animations flicker. :(

[Alberts Muktupāvels (muktupavels)]

Dissabled because GTK+ 2 and GTK+ 3 can not be mixed in one application. Currently it is simply not possible to build with metacity support.

Yes, I have started work on GTK+ 3 port for gtk-window-decorator. I hope it will be ready for Utopic...

[Fred (eldmannen+launchpad)]

Alright. I see!
Glad to hear someone (you) working on it, and glad you're making good progress.

How come GTK+ 2 support was disabled before GTK+ 3 support was ready?

I hope that you get GTK+ 3 support done in time for Utopic! :)

[mistahowe (mistahowe)]

Is there any way to easily revert to metacity 2.x.x if you are on 14.10? There don't seem to be any apt packages earlier than 3.12.0 on the main repos.

[Fred (eldmannen+launchpad)]

How is the progress going?

There has been the feature freeze, and also the beta 1.

[Matthieu Baerts (matttbe)]

Tested with Cairo-Dock session, everything works fine! Thanks!

[Timo Jyrinki (timo-jyrinki)]

The fix is waiting in a landing PPA for the FFe approval.

[Fred (eldmannen+launchpad)]

The patched version in the landing-016 PPA fixed it for me. :)

[Iain Lane (laney)]

Ok, go for it. Please publish really soon to get this in before the beta freeze.

[Alberts Muktupāvels (muktupavels)]

Why it is so long in proposed? Is there any reason why branches are not merged?

[Marco Trevisan (Treviño) (3v1n0)]

There's a beta freeze ongoing, it might be caused by that.
