@Marco: Below is debug output from running compiz --replace. I ran this command with the external monitor already plugged in. After restarting compiz, the window decorations draw correctly on both screens.
1) Plug in external monitor 2) Open a terminal 3) Type compiz --replace. UI becomes unresponsive (the mouse still moved around, but I couldn't interact with windows) 4) I switched to another VT to see what was happening. top reported apport was running 5) I switched back to VT7; compiz restarted steve@aether:~$ compiz --replace compiz (core) - Info: Loading plugin: core compiz (core) - Info: Starting plugin: core compiz (core) - Info: Loading plugin: ccp compiz (core) - Info: Starting plugin: ccp compizconfig - Info: Backend : gsettings compizconfig - Info: Integration : true compizconfig - Info: Profile : unity compiz (core) - Info: Loading plugin: composite compiz (core) - Info: Starting plugin: composite compiz (core) - Info: Loading plugin: opengl compiz (core) - Info: Unity is fully supported by your hardware. compiz (core) - Info: Unity is fully supported by your hardware. compiz (core) - Info: Starting plugin: opengl compiz (core) - Info: Loading plugin: copytex compiz (core) - Info: Starting plugin: copytex compiz (core) - Info: Loading plugin: imgpng compiz (core) - Info: Starting plugin: imgpng compiz (core) - Info: Loading plugin: move compiz (core) - Info: Starting plugin: move compiz (core) - Info: Loading plugin: place compiz (core) - Info: Starting plugin: place compiz (core) - Info: Loading plugin: commands compiz (core) - Info: Starting plugin: commands compiz (core) - Info: Loading plugin: vpswitch compiz (core) - Info: Starting plugin: vpswitch compiz (core) - Info: Loading plugin: mousepoll compiz (core) - Info: Starting plugin: mousepoll compiz (core) - Info: Loading plugin: resize compiz (core) - Info: Starting plugin: resize compiz (core) - Info: Loading plugin: compiztoolbox compiz (core) - Info: Starting plugin: compiztoolbox compiz (core) - Info: Loading plugin: regex compiz (core) - Info: Starting plugin: regex compiz (core) - Info: Loading plugin: grid compiz (core) - Info: Starting plugin: grid compiz (core) - Info: Loading plugin: snap compiz (core) - Info: Starting plugin: snap compiz (core) - Info: Loading plugin: wall compiz (core) - Info: Starting plugin: wall compiz (core) - Info: Loading plugin: unitymtgrabhandles compiz (core) - Info: Starting plugin: unitymtgrabhandles compiz (core) - Info: Loading plugin: session compiz (core) - Info: Starting plugin: session compiz (core) - Info: Loading plugin: animation compiz (core) - Info: Starting plugin: animation compiz (core) - Info: Loading plugin: expo compiz (core) - Info: Starting plugin: expo compiz (core) - Info: Loading plugin: workarounds compiz (core) - Info: Starting plugin: workarounds compiz (core) - Info: Loading plugin: fade compiz (core) - Info: Starting plugin: fade compiz (core) - Info: Loading plugin: ezoom compiz (core) - Info: Starting plugin: ezoom compiz (core) - Info: Loading plugin: scale compiz (core) - Info: Starting plugin: scale compiz (core) - Info: Loading plugin: unityshell compiz (core) - Info: Starting plugin: unityshell WARN 2014-04-14 11:54:47 unity.glib.dbus.server GLibDBusServer.cpp:579 Can't register object 'org.gnome.Shell' yet as we don't have a connection, waiting for it...
