This is strange. I cleanly reinstalled Opie, and then following the dual guide installed GPE.
Now from the command prompt I can switch between Opie and GPE.
In GPE I've made a gotoopie.sh script in /usr/bin
When I run it, I go to Opie. I've also made a desktop file placed it in applications folder and see the icon. The desktop file calls this script.
But when I tap it, I see the expanding box, indicating it was run, but I don't get switched to Opie. Why?
This has got to be something simple, but I can't figure it out. What have I done wrong?
