1. org.gnome.desktop.wm.preferences.gschema.xml: Main schema file with all settings under preferences. Here default value is 'appmenu:close'.
2. 10_ubuntu-settings.gschema.override: This one is from ubuntu-settings package and changes default value to 'close,minimize,maximize:'. 3. 20_ubuntu-gnome-default-settings.gschema.override: This file came from ubuntu-gnome-default-settings packages and is again changing default value to 'appmenu:close'. Your problem is ubuntu-gnome-default-settings package as it changed default value. In trusty it was button- layout=':minimize,maximize,close', but now in vivid it is 'appmenu:close'. This is not a bug and there is nothing to fix. Upstream changed button- laytout and Ubuntu GNOME is just following this change. Main problem here is that there is no way to set default values for each session. ** Changed in: gnome-flashback (Ubuntu) Status: Incomplete => Invalid -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1431816 Title: All windows missing Minimize and Restore buttons To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-flashback/+bug/1431816/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
