GNOME classic session using Compiz does not switch windows on Alt+TAB

[dronus]

On Ubuntu 12.04, the GNOME Classic session based on Compiz does not provide the Alt-TAB window switching. The 'no effects' session (based on metacity) however does.

The reason is that the Compiz used does not include the Compiz 'switcher' plugin. It is contained in the compiz-plugins package, which is not installed.

Should be fixed cleanly: The package gnome-session-fallback should not provide a session that depends on compiz, without providing compiz and the compiz-plugins package. And maybe a script that add 'switcher' to the default enabled plugins (seems to be using the gconf backend, so it just need to bring an additional gconf file I guess) is needed.

If gnome-session-fallback should not depend on compiz, the Classic session using compiz may move to a new package, and this one only contains 'no effect' variant then.

This is actually a variant of bug #971051 which is filed against compiz, which is wrong I guess, as it is not a problem of compiz itself, but rather its configuration in the gnome fallback package.

This bug was fixed in the package compiz - 1:0.9.12.1+15.10.20150805-0ubuntu1

---------------
compiz (1:0.9.12.1+15.10.20150805-0ubuntu1) wily; urgency=medium

  [ Alberts Muktupāvels ]
  * Change icon size back to 48px in application switcher plugin. (LP:
    #1237057)

  [ CI Train Bot ]
  * New rebuild forced.

  [ Dmitry Shachnev ]
  * Move window switcher plugins to compiz-plugins-default. (LP:
    #971051, #1465647)
  * debian/compiz-gnome.gsettings-override: Remove unityshell from
    active plugins, and add switcher. (LP: #1469086)

  [ Eleni Maria Stea ]
  * It fixes the 3d windows plugin. Problem: The 3d clipping is
    performed in viewing space (modelview transformation) and should be
    done inside the shader when we use shaders otherwise the viewing
    space pipeline operations will be ignored. Compiz used to perform
    the clipping inside the td plugin using pipeline functions, then it
    was loading a generic shader program (no clipping operations) to
    render the windows and then it rendered the 3d quads around the
    windows using the pipeline (so these were clipped correctly). (LP:
    #1395697)
  * Sometimes the MultipleCubes, Automatic or OneBigCube option might be
    set although we are not in multimonitor. Modified the 3d windows
    plugin to check the number of monitors as well.

  [ Marco Trevisan (Treviño) ]
  * Window: add clientFrame(), to get the client-side decoration extents
    (LP: #1422768, #1436553)
  * Window: compute the correct output using the absolute window
    position (LP: #1475721)

  [ Martin Wimpress ]
  * align MATE profile more closely with Marco

  [ Stephen M. Webb ]
  * Fix a FTBFS when -std=c++11 is used. (LP: #1477654)
  * Fixed the Compiz manpage and --help message to agree with the actual
    command-line options supported. (LP: #1475508)
  * force Compiz to build using C++-11 (required by build dependency
    libgtkmm-3.0-1). (LP: #1477978)
