[maemo-developers] [LONG] New user/devel and newbie question

[From: Ulises]

Dear all,

First of all, hi everybody, as the subject says, new user (and
hopefully new developer here).

I got my old Nokia 770 a couple of days ago and I absolutely thrilled
with it. First time mobile user and all, you can't blame me ;)

Anyway, I've been using the thing for a couple of days and I decided
to try to start developing some stuff, just for fun. So I set out to
install the SDK for OS2007 (I installed the HE 2 days after I got the
tablet). Installing maemo 3.2 is no problem (I'm running Ubuntu Gutsy
on my desktop/laptop) however something puzzles me. When I start the
environment (on the Xephyr server) not everything seems to be
available, e.g. no browser, no applets, etc. but I can live with that.
What really bothers me is that when I do a af-sb-init.sh stop, the
desktop doesn't stop. It just stays there, even though the script
outputs that the desktop isn't running anymore. A ps aux shows me  all
the qemu-arm processes happily running. A killall fixes this, but this
is certainly not the best way to go. What's even stranger is that on
the X86 target it all goes dandy but not on the ARM target. Any
ideas/docs I should read? I've spent the last week RTFMing my eyes off
and certainly exhausted google.

Thanks for reading and happy hacking!

Below there's a snapshot of the session:

Start the Xephyr server:

Note: the desktop is still running, only after a killall

leads to the message above

Again, thanks for reading and any help will be greatly appreciated.
