That's sort of where I was thinking: Make it "harder" or at least something requiring more than a button push. I know when I was having troubles with not being able to use the mouse, I was able to get to a virtual terminal, drill down to the appropriate file and edit it to switch desktop environments. I'm not saying it has to be THAT obscure, but something requiring a wee bit of effort may suffice... If that's not enough, could it be set up so that there is no way to permanently set to GNOME, requiring users to jump through hoops any time they reboot? That way, only those who wanted it badly enough would bother to go to the terminal every time. <blockquote type="cite">On Jun 25, 2010 8:03 PM, "Walter Bender" <<a href="mailto:walter.bender@gmail.com">walter.bender@gmail.com</a>> wrote: Raul had what I had thought was a nice compromise solution: to eliminate the control-panel section for switching. Then the switch would be a deliberate act from the Terminal, presumably by deliberate action by the student. Then any "damage" would be in the realm of violating the social contract between teacher and student ("I defaced my text book") as opposed to an accident ("the dog ate my homework"). In La Rioja, they are just beginning to discuss the topic, but the Raul suggestion resonated with them. regards. -walter On Fri, Jun 25, 2010 at 7:16 PM, Bernie Innocenti <<a href="mailto:bernie@codewiz.org">bernie@codewiz.org</a>> wrote: > This morning we had...-- Walter Bender Sugar Labs <a href="http://www.sugarlabs.org" target="_blank">http://www.sugarlabs.org</a> _______________________________________________ IAEP -- It's An Education Project (not a laptop proj...</blockquote>
