Never heard of scratch.
Just downloaded the scratch package for Debian wheezy.
When I do ssh -X raspberry scratch a blank window pops up. I can't find a way to interact with the window.
I would omit the addition of the user to the sudoers file or sudo group in a school environment. That gives root access to the user which may not be desirable.bredman wrote:The correct method to add a new user is described in the wiki
