How to change default desktop for all users

[MarieRivier]

Thanks!

I love that thinking!

...

Best regards, Șerban.

I like how you see things...
The idea of freedom is, sure, attractive and I like that in GNU too.
But too much freedom in a n high school might lead to unwanted development.

I'd love to be able to trust students ... But if they have the littlest way to break things, they'll use it.
We've rebuild our classrooms last year and they looks like they have been used since 5 years already... (lights broken, emergency signals destroyed... ) It might be the doing of just a few of them but it clearly show that I can't trust them all with keeping their environment clean and clear...


To set a big project with wallpaper designing and all these things, I already discussed it with teachers and none of them wants to take that kind of project, the dean thinks it as a good idea if we have teachers to take the lead but won't force teachers to do it if they don't want to.
So for the moment I'm out of move in that regard. Next year we'll have a new Art teacher so I'll try to bring her in that project.

For the moment, I think I'll go with trinitad's idea

The dirty way to do it would be to rename the backdrops folder to oldbackdrops and create a new folder named backdrops that contains only your new wallaper with the same name as the currently default wallpaper. I'm not sure if series point upgrades would add the old wallpapers back in or not though. The new wallpaper must be a .png file the same pixel dimension as the old one since the default is named that way. The problem is since the wallpaper in XFCE can be accessed from any image file on the system DE tinkerers could still replace it.

It might be a dirty way but I'll be able to set a default wallpaper for every one...

If then they change it to set a sexual assault as defaut wallpaper (I think that will happens a few week after deployment) for one or two desktop, they are free to do it... and to get scolded for it.
But I want to try to inspire them a feeling of belonging even if they will just smug that away without event thinking about it...

And for your arguments, Sir Serban, I totally agree !
School is intended to provide a safe environment to develop skills for everyone.
But the best way to do that is to be, financially, able to procure that environment. If we could do that the dean would have gone to a firmly secured paid solution, but we can't, so I try to provide them with a good environment at a lower cost.
Environment that I try to make as secured as I can without cutting to much of their freedom, cause I want them to learn to be free internet citizens by themselves.
That's why I have to thank you for the usefulness of LinuxLite that can revive old computers and make them running again, it will helps some of our poorest students that can't have a computer at home.
Because school is meant for everyone one and that means even those who will do everything in their capabilities to destroy stuff and they are legion in high school...
