Username that Resets on login
 

Hello,

Context: I'm a high school math teacher and extremely new to Debian/Linux. I've got ~20 laptops that are not allowed to connect to the schools internet. To perform updates, I literally have to haul these machines home to update them.

Curious students keep messing with the display settings etc. (which I approve of) but I would like to have a 'locked' version, where students would login as something like Username: student Password: student, which would load a clean version every time.

Thank you.

if you had yourself, as administrator/root you can update / admin as necessary.
you could also have a separate admin/root account & another for yourself, as a 'normal user'.
also you could have another set of account(s) for students to use & yet another set for teachers to use.

- they could all have different levels of access - as well, & all set within their user profile, as set by you . . .

I'm not sure this is what you have in mind, but it's perfectly feasible to write a simple script which removes a users personalisations on log off. It could be something as simple as removing /home/user_name and replacing it with a "default" clean home directory (or just clearing out all of the dot files and directories in the user's home directory).
