With fc6 compiz and AIGLX got into fedora and we should improve the user
expirence with this in F7, not make it worse.
We also need to integrate compiz better into our desktop.
Right now its easy to active and to disable with the "Desktop Effects" app.
But this does not work correctly due to some regressions.
1)Compiz gets started from the session manager and so its not possible
to switch compiz->metacity because compiz restarts itself.
2)The next thing is that if compiz is configured to use 4 Viewports and
Metacity 4 Workspaces compiz will ignore its own setting and use the
metacity one until X is restarted.
The god news are that this stuff is fixed, we only need to get the fixes
into fedora ;)
There is a patch for 1) in bugzilla:
https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=229113
As for 2) I have sent a patch upstream which is merged into current git.
It adds a --ignore-desktop-hints commandline switch to compiz which
fixes this behavior. We need to either make it the default by patching
compiz or start compiz with this option from "Desktop Effects". ( I can
send a patch for desktop-effects/compiz if needed)
After doing this the switching between metacity and compiz should work
as fine as it did when fc6 got released. (The current f6 updates have
the same problems). I am using a custom compiz package(git snapshot)
with this changes and it works without any problems and is stable. (With
compiz-0.3.6 the window decorator sometimes crashes but this is fixed in
git; have not seen any crash with it). We have shipped a git snapshot in
fc6 so this should not be the problem, also 0.4 should be out sometime soon.
The next thing is libwnck. Compiz supports the "Always on top" feature
but it is not selectable in the menu because of a bug in libwnck. There
is a patch for it in the gnome bugzilla:
http://bugzilla.gnome.org/show_bug.cgi?id=352383
The patch in question is the _NET_WM_STATE_ABOVE.patch we should get
this into our libwnck package. We already have patches in libwnck and
gnome-panel for compiz integration so it would not hurt to add this
small patch too.
There is also the viewport.patch in this bugzilla entry. I am not using
this myself right now (so I can't comment on its stability) but we also
should aim to get this patch in too.
P.S: please don't start a compiz <> beryl flamewar
