How to block wallpaper?

[kristerger]

Hello, I have a problem that has overcome me and I need help, or some idea how to solve it. In an educational insti tution we have 50 PCs in a computer room and we need students to not change the wallpaper, bars, menu, etc (configurations). How can I solve that? Thank you in advance for any help or suggestions you can give me!

Hi
you will probably have to give us just a little more information, like the OS's and their year, version.

Since I'm just a hardware kinda guy I'll wait for somebody much more knowledgeable than me to pop in.

But...again...GOOD ON!!

Theren used to be a gui for this way way back in KDE3 days, but it is still possible to do via cinfig file edits.
Some brief links
https://userbase.kde.org/KDE_System_...k/Introduction

https://userbase.kde.org/KDE_System_...ion/Kiosk/Keys <----- this has the list of things that can be restricted
Specifically : https://userbase.kde.org/KDE_System_...e_Restrictions

From what I can tell, you can add these to a newly created section in the kdeglobals file to restrict actions, etc.

Youll probably want to setup a kiosk.

It looks like there used to be a kiosk admin GUI tool, but I cant find it in the repos. Looks like youll have to do it manually. If you have 50 machines, you can probably set it up on one and then simply copy the config file to the others.

An INTERESTING thread and the several responses are worthwhile.

There used to be what was called an "Immutable" setting you could put in the KDE config files and lock down almost every feature on the desktop.

They talk about it here: https://userbase.kde.org/KDE_System_...k/Introduction

I think that you are quite correct vinny.

I find this thread just fascinating!

I would very much like to attempt to do it with my KParadigmShift tweak but I'd probably screw it up and never know where I screwed it up. lol

Has been an attempt to revive that.

How do I install kiosktool on kubuntu? With the command sudo apt-get install kiosktool does not work. I want to try this solution that seems to be good and just what I'm looking for. On google I found an rpm package that should convert it to deb.

I think that package is dead. If it hasnt been updated in a few years, I wouldnt trust it to do the job properly. Id say your best bet is to just edit the file manually.
