Comment 12 for bug 296028

found this temporary workaround:

create a bash script

#!/bin/bash
gconftool-2 --set /apps/aisleriot/show_toolbar --type boolean true
gconftool-2 --set /apps/aisleriot/fullscreen --type boolean false

..and when your grandparents call you tell them to press alt+f2, no not one-after-another, press and hold alt,....et cetera..............
