I've followed this guide to set up a Kiosk pc: http://www.instructables.com/id/Setting-Up-Ubuntu-as-a-Kiosk-Web-Appliance/
Small difference is that I did it all with the admin account and I didn't use the xscreensaver because the pc is used as a monitoring device ( loads an internal webpage which shows all webserver states etc ).
The only problem I have now is that while I'm in the kiosk mode session I can't access the pc with remote VNC. I tried adding a command to manually start vinoserver in the kiosk shell but to no avail.
As I'm fairly new to this I hope you can help me.
You probably need more information, but I'm unsure what you need, so please just tell me whatever info I can provide and I'll add it asap.
EDIT: As an additional question, I'm unable to prevent the system from going to standby even though the normal gnome session is set to always on. Any help on that account would also be welcome
