How to change default desktop for all users

[Şerban S.]

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.


You might be better off to just brand the ligthdm login screen and allow the users to use whatever wallpaper they want. Other options are auto scripts at the end of boot (after Xorg starts), or conky with which you could brand no matter what wallpaper was selected.

Otherwise full boat you need to add a package and a license for/with the brand and then use OEM install which currently is unavailable.Kiosk mode could make the wallpaper persist but other Lite apps would be unavailble like updates, tweaks, and software manager which could be automated similar to an immutable methodology but what happens then when there's a problem?

Thanks!

I love that thinking!

My reluctance over this strange request, resides in the fact that the idea in itself, violates the GNU-GPL licence, that states clearly the freedom of choice at the user level.
So, imposing forcibly a specific element (regardless the type), is out of the boundaries of what we call "freedom" and "freedom of choice", which gets us back to the commercial software world.
It is also against the SPIRIT of the FOSS movement!
So, a legitimate question is: Why bother?
Specifically, Why bother to install Linux (whatever flavor...) if you love the forced solutions software, and generally speaking, the commercial world?


A different approach

I'm less found of the people that throw a stone into the lake, than wait to/and laugh at those who struggle to get it out.

So, I've been thinking of something more lucrative.
Since we're dealing with a learning environment -- at least, this is the theory when speaking of a school! -- a far more interesting solution I belive is the following:

1. Ask each user to design its own image for desktop background. This can be a school level creativity project, for all levels of students.
2. Encourage collaboration in the use of the available tools for this specific task: Inkscape (vector graphics) and GIMP (photo editing).
3. Help the students build the creation teams.
4. Provide the school logo that is required to represent the school.
5. Further more, ask the students to design a logo for the school.
6. Gather the community of students to vote for "The greatest school logo", and "The greatest desktop background". This can be done online, so it will be a complex project for the entire school.
If my understanding is right, there is a network of 20 systems. There you have it! Mail practice, HTML editing, site building, there are a plethora of options.
And this can go far beyond the simple task of creating a logo and a background. This way, you can discover each and every student's native skills that worth developing.
Management skills that are involved, are the most in demand nowadays. So, as I see it, it is a WIN-WIN situation, as opposed to the previous idea.
7. Ask the more advanced students to pack the top 20 (or 30...) backgrounds and install them in a custom directory, so they are available for each and every user.

Obviously, this is what I would do.
I strongly belive that school, has to be the place where we develop skills of communication, team building, self management, creativity, and many more skills.
But we have to accept that creativity, is like any organ or muscle, that needs a thorough training. The school, ANY SCHOOL, is supposed to provide exactly this environment.

Do we do this now?
