Nathan: Thank you for taking a look. I didn't port it, I used the Debian Xephyr from the chroot, and it worked fine in Diablo. But the "vanilla" Xephyr no longer works properly in Maemo 5.

My temporary solution, so that I can keep working on Easy Debian, is to use run LXDE in a vncserver on :1 and view it in Maemo vncviewer via "localhost:1". It isn't a great solution, but at least I have a keyboard in my secondary WM.
