Hi Miklos,
For some reason, now I'm having trouble reproducing the ownership change of /run/user/1000/dconf/user to root using my method from [1]. I've tried it on two Jessie installations, one has traditional sysvinit and another has systemd-sysv. Both systems are fully updated, the version of systemd is 215-11. Can you confirm whether your method (in Gnome session) still works in the current Jessie or not? Does /run/user/1000/dconf/user get owned by root? [1] https://bugs.debian.org/766464
