elementary Compiz Profile needs packaging

No, it WILL NOT go into eBuild, and we have a blueprint about that.

sry, I meant to package it

Attaching my "first draft." Looking forward to feedback.

We have a branch here for the defaults. It needs to be packaged and installed

https://code.launchpad.net/~elementary-design/+junk/compizprofile

It appears that /etc/X11/Xsession.d/65compiz_profile-on-session has no effect because it sets the profile to "ubuntu" but the actual profile is called "unity" in CCSM and in GConf.

There's /usr/share/gconf/defaults/10_compiz-gnome file which sets the list of enabled profiles. It doesn't set the default profile though, I wonder if it can be done in GConf at all. Editing that file is not needed, we can set all we need in session, i.e. /usr/share/gconf/pantheon/default/20_pantheon-gconf-default.

For profiles themselves I've found only /apps/compizconfig-1/profiles/ folder in GConf.

Yes. I am going to export the gconf part as a file. Than we could package
that gconf structure file (xml) ? Its just export, import, and selection.
I think that's it...

Import/export is not an option because it screws localization and is completely wiped by resetting to default, among other things. It would be better to follow the way it's implemented upstream, it seems to be much cleaner.

All compizconfig-1/ keys in GConf don't seem to have a schema for themselves. Looks like they're generated based on profile flat file.

/etc/compizconfig/config is an interesting file, looks like that's how Compiz profile is picked nowadays

/usr/share/gconf/defaults/10_compiz-gnome also sets the plugin list for Unity profile, as if /etc/compizconfig/unity.ini and the profile itself aren't sufficient. Man, Ubuntu defaults are scrattered and dirty, as usually.

So what are we going to do ? Do a patch package for compiz-gnome, or package our own compiz-gnome package?

Custom package with blackjack and hookers, for sure

Okay, in #compiz I was told that the defaults are stored in XMLs in plugin sources. They remain in XML form on user's system, and CompizConfig (including CCSM) uses those XMLs as defaults. Packages with plugins also ship GConf schemas, which is interesting...

So what can we do?

So if we can't change the default, we could say pantheon that it should load the pantheon profile...

Eduard: okay, go figure out how profiles are stored in 0.8.x and how to switch them. But I'm pretty sure we can change the default in 0.8.x

ok, /usr/bin/unity , the start script for unity, sets the compiz profile partialy with shell variables ( If I see that right)

In our case that would be COMPIZ_CONFIG_PROFILE='fooo' .

 I dont realy know why its called foo, tough.
 I imported it via ccsm. Please take a look at /usr/bin/unity

Here is something that may help :

GCONF:

Import compizprofile into /apps/compizconfig-1/profiles/pantheon

Make /apps/compizconfig-1/profiles/default an exact copy of /apps/compizconfig-1/profiles/pantheon

That should likely be changed in the template file for the gconf tree creation for each user, so new created users get that config automaticly. Also the default values for these keys should be the ones that we set, so users can easily get back to the standard behaviour.

FILESYSTEM:

Make /etc/compizconfig/config look like this:

[kde4_session]
backend = kconfig4
integration = true
plugin_list_autosort = true

[kde_session]
backend = kconfig
integration = true
plugin_list_autosort = true

[gnome_session]
backend = gconf
integration = true
plugin_list_autosort = true
profile = pantheon

[general]
backend = ini
plugin_list_autosort = true

[general_pantheon]
backend = gconf
integration = true
plugin_list_autosort = true
profile = pantheon

[general_ubuntu]
backend = gconf
integration = true
plugin_list_autosort = true
profile = unity

Please be aware that using [general_pantheon] would be the best decission, instead of using [gnome_session] .
When you do this, and it works for you, I think you can remove profile = pantheon from [gnome_session] .

Please look at the TODO part for more info about that.

what means to add profile = pantheon to the existing config file, at the end of [gnome_session] , one line over [general], which is present in Ubuntu, or create a new one.

WARNING: I dont know if we realy need this file:

Make /etc/compizconfig/pantheon.ini look like this:

[core]
s0_active_plugins = core;composite;opengl;compiztoolbox;decor;vpswitch;snap;mousepoll;resize;place;move;wall;grid;regex;imgpng;session;gnomecompat;animation;fade;workarounds;scale;expo;ezoom

Suggestion: keep both files as close as possible to that one in Ubuntu (becouse of session compatibility)

TO DO: use something like [pantheon] instead of [gnome_session] for the load of our session (Ubuntu does use something like [general_ubuntu]). Maybe that could be realized trough setting the environmental variable for compiz config profile (?) : COMPIZ_CONFIG_PROFILE='pantheon' in the start script for the session loading for pantheon.

use upgrades directory for later changes via apt-get software updates (?), please see in Ubuntu for /etc/compizconfig/upgrades as a template for that.

Thanks for your work on this, but compiz can eat a ****.
