I need to set up one of the accounts in my Xubuntu 11.10 machine as essentially a kiosk. I have set up the desktop and assigned only certain icons to the panel, and now I just want to lock the panel so that it can't be changed. (It would be even better if the panel could easily be changed with sudo rights when I need to change it over time.)
In the past I accomplished the same thing in Ubuntu using Pessulus, but I read that Pessulus does not work in Ubuntu 11.10 so I switched to Xubuntu with upgrade last week because I read that XFCE supports a kiosk mode. I had to upgrade because as far as I can tell it was the only way to resolve an unrelated hardware problem that I was experiencing with the printer.
I tried turning on Kiosk mode as described here. I created file /etc/xdg/xdg-xubuntu/xfce4/kiosk/kioskrc with the following contents:
[xfce4-panel]
CustomizePanel=root
It seems that now the account in question can right click on the panel, add a launcher and use it, but when the account logs out and back in the launcher is no longer there. If this is the desired behavior of XFCE's kiosk mode then it is not what I am looking for. I need to prevent this account from being able to modify the panel. I guess it is possible that I did something wrong in trying to set up kisok mode.
Worst case I guess I could disable right clicking for the user, but that solution seems like it might lead to trouble when I realize that some program needs right click to function properly. I researched the preventing right click option, but the only solution that I found here seemed to be a system wide solution, and I really need for the other two accounts on this machine to have right click functionality.
I am sure that I am not the only person who wants to do this. I can think of many use cases for locking down the panels in Xubuntu. I have spent quite a while searching for a solution, but have not yet found one. I have used Ubuntu for five years now, but it has always just worked for me so I don't have much experience editing configuration files. Can you point me to a guide for what I am trying to accomplish?
