Comment 2 for bug 1170047

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.
