Dear Bernhard, thank you very much for your reply.
The bug is, like I see it, that the applications cannot find the gsettings schema directory. When setting export GSETTINGS_SCHEMA_DIR="/usr/share/glib-2.0/schemas/" in my .xinitrc I can launch GTK and GNOME applications when the xsession ist started with startx. Therefor setting GSETTINGS_SCHEMA_DIR in /etc/environment maybe fixes the issue, which I have not tried yet. Shall I resubmit the bug against gsettings-desktop-schemas package? Yours sincerely, Adrian -- With many greetings from Leipzig, Germany.
