I have sent Easy Debian 0.9.51 to Extras-devel. LXDE keyboard focus is now completely fixed. You can treat LXDE like any other Maemo window. This version adds a Maemo-side script, /usr/bin/debian-lxde that does the same thing that xephwm5 was doing in the chroot, except it uses the new fixed way that never loses keyboard focus. It now depends on wmctrl and zenity in Maemo, which adds some bulk to the installed size, but the results are worth it. I have also caved to rebhana's pleading; the new script starts LXDE using debbie-sue. Switch this to debbie if you prefer the old behaviour.
