Currently the grandkids are using Mint xfce to play games on Steam or locally installed. Also, flash games on the internet, youtube, PBS, Netflix and typical kid interests. I run maintenance on their pc every ten days or so. Sometimes I'll find that they have goofed-up several things on the xfce desktop. I'm looking for a way to permit their haphazard pc use without destroying the desktop. I need a bulletproof desktop environment and feel confident that a few of you geezers out there have already found an answer. Maybe an openbox session with only the visible app launchers that are absolutely necessary for their clicking craziness?
