How can I create a very restrictive account for my 3 year old.
Limit access to a couple of specific applications
Disable left-click
Disable keyboard shortcuts
Disable resolution change/rotate
Lock tool bar
Limit the number of window that can be opened at one time
etc
Someone should petition the developers to include a predefined group “Toddlers” to the default user groups, having locked-down accounts, more restricted than ordinary users, such as no right-click, preventing multiple consecutive clicks on the same desktop icon, a predefined low sound volume, a drastically stripped-down menu (restricted to just the Logout button) and with some simple drawing tools and games on the Desktop (with cool, large-sized and self-explaining icons). Of course, all this should be provided for KDE too.
Slightly out of topic but I will answer nonetheless.
Actually I am serious, at 3 he already use it better than my mother.
From powering it up, to browsing the menu to launch firefox (default page are flash games for toddlers), tuxpaint or his favorite gnome game, he is surprisingly comfortable using a computer.
I have setup an old laptop for his sole use so losing data is not a concern.
Only issues at this time is that he doesn’t close applications and tend to “explore” the menus.
I have GCompris for my son. he also uses tuxpaint to create his monalisa
some times he uses opensuse writer in big font to learn alphabets.
The account is a default kde account with comics plasmoid.
