A bit of an odd question:
I want to change the list of sessions available on (KDM|GDM|LightDM|some_other) to a user, without affecting the sessions available to others.
Specifically, I have one user that is not very computer-savvy, and I want to prevent the said user from changing session type accidentally. I dont want this to affect the other users.
Can it be done ? I'd gladly switch my display manager to whatever one supports this
