Light-locker package provides gschema.xml file in /usr/share/glib-2.0/apps.light-locker.gschema.xml. When new gschema.xml added to this directory, glib-compile-schemas should be invoked to update cache. Why is this matter? Xfce Power Manager handles Light-locker settings. If those settings is not available through gschema interface (I think it's dconf/gsettings related things), then it won't provide Security tab for control those options. This tour of Xfce 4.12 contains screenshot and description of Security tab for Power Manager: http://www.xfce.org/about/tour Reproducible: Always Steps to Reproduce: 1. Install xfce4-power manager (as a part of Xfce) 2. Install light-locker 3. Open Xfce4-power-manager and see that there's no Security tab. Another way is to run in terminal light-locker command to see that apps.light-locker schema isn't found so it won't store settings in runtime. Actual Results: No xfce4-power-manager Security tab; Light-locker don't store serttings in gschema interface (dconf/gsettings related things). Expected Results: After installation of light-locker (beacuse it's optional) gschema.xml files should be updated (recompiled) and xfce4-power-manager should handle settings and show Security tab. gnome2-utils.eclass contains necessary commands to update gschemas. 4 commands should be invoked after installation and after removing the package. To fix this bug, ebuild should be modified to run gnome2_schemas_savelist and gnome2_schemas_update. Appropriate inherit options also should be added. Here's how it looks (I post only diff): ingerit autotools-utils eutils gnome.org gnome2-utils pkg_preinst() { gnome2_schemas_savelist } pkg_postinst() { gnome2_schemas_update } pkg_prerm() { gnome2_schemas_savelist } pkg_postrm() { gnome2_schemas_update } P.S. I notified maintainer via email and he advised me to file a bug. I found a solution which fix this issue. I'm sorry for my bad English and for such rough description because I'm not a developer and it's hard to properly name all those things.
Created attachment 417468 [details] Fixed ebuild that invokes neccesary commands. Original ebuild with added commands to udpate gschema.xml after installation of light-locker.
I have fixed this today along with a bump to version 1.7.0. I used a different ebuild from what you sent but your hints were very valuable. Sorry for the time it took to get it done. Thanks, Denis.
