According to your bug description, xfce4-session can be configured with the kiosk mode configuration file, but both xfce4-panel and xfdesktop can not, correct? Can you please attach your kioskrc file, so we can see what you have tried and maybe confirm it?
On top of that, please file an upstream bug report to inform the Xfce team about this problem. https://bugzilla.xfce.org/ ** Changed in: xfdesktop4 (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1170047 Title: kiosk mode doesn't work at all To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xfdesktop4/+bug/1170047/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
