Good morning all.

So I work with a disabled guy and he has a computer. This guy asked for assistance, I put windows xp on his computer and I discovered that he loves deleting files (he managed to delete the system making it impossible to boot...)

I decided to try ubuntu, it will be a better solution than windows XP I'm sure he will love the colors... I want to lock down his account to absolutely block pornography access, block any way that he can delete applications or install new ones.

I also want to lock the desktop so that he can't delete the icons or change wallpaper or whatever... otherwise he will empty the desktop change the wallpaper and come again and again.

It will be extremely nice if some one could have the patience to solve my problem.
thanks in advance.

Edit: So the thing if he find a way changing the wallpaper he won't be abble to put it back and will probably delete or watever... and in the desktop as i know you have the shortcuts for the applications like google chrome... if he delete I don't even know were linux put the applications once installed ^^'. and is there any "parental control" ? Edit: thanks :)
