gdb is a debugger. There's a Debian package called gdb. Please install it and try again! Maybe then you'll get a useful message. Either version, Lenny or Squeeze should be fine, whatever comes with fewer dependency trouble.

Well, as long as I can't sort out the set-focus issue I don't think a Squeeze-only ED will be very useful. I'll keep on searching.

Not really.

Edit:
I think I've found the set-focus problem but unfortunately I don't know how to solve it yet.

In the ED image there is the script /usr/bin/xephwm5:

Code:

#!/bin/sh
##################################
#Change these two variables to the WM of your choice.
WMNAME="$1" ; WMEXEC="$2"
[ "x$WMNAME" != x ] ||  WMNAME="Xephyr"
[ "x$WMEXEC" != x ] ||  WMEXEC="startlxde1"
##################################
export DISPLAY=:0
export TSLIB_TSDEVICE=/dev/input/event3
export TSLIB_CALIBFILE=/etc/pointercal
export GTK_MODULES=libgtkstylus.so
zenity --display=:0 --info --text="Welcome to Easy Debian LXDE. This window is needed to gain keyboard focus in LXDE. Click OK." &trl -l
/usr/bin/Xephyr :1 -screen 800x480 -br -ac &
while [ "x$PARWIN" = "x" ] ; do
  # wait for Xephyr window to appear
  export PARWIN=`wmctrl -l | grep -i $WMNAME | awk '{print $1}'`
done
DISPLAY=:1 ; habak -mf /usr/share/fonts/truetype/DroidSans-Bold.ttf \
     -ht 'Ctrl-back to return to dashboard.'
DISPLAY=:0 ; wmctrl -i -r $PARWIN -T 'Easy Debian'
wmctrl -i -r $PARWIN -b toggle,fullscreen
while [ "x$TWOWIN" = "x" ] ; do
  # wait for Zenity dialog to pop up...
  export TWOWIN=`wmctrl -l | grep -i Information | awk '{print $1}'`
done
#echo window id: $TWOWIN
wmctrl -i -a $TWOWIN
#/sbin/qobi-wmhint-fix $PARWIN
/usr/bin/set-focus $PARWIN
wmctrl -i -a $PARWIN
/usr/bin/$WMEXEC
killall Xephyr
export DISPLAY=:0

Towards the end there is this line:

Code:

/usr/bin/set-focus $PARWIN

$PARWIN contains a hexadecimal number, the identifier of the ED window in Maemo.
In my case this number is 0x04000002:

Code:

~ $ debbie wmctrl -l
[..]
0x03800059  0 Nokia-N900-02-8 Fotos
0x0380005c  0 Nokia-N900-02-8 Fotos
0x01800cd3  0 Nokia-N900-02-8 hildon-home
0x01800de0  0 Nokia-N900-02-8 hildon-home
0x01800f9f  0 Nokia-N900-02-8 hildon-home
0x018013ba  0 Nokia-N900-02-8 hildon-home
0x03217172  0 Nokia-N900-02-8 m5v3e
0x04000002  0             N/A Easy Debian

So I called set-focus manually from within the Squeeze image but got the following error message:

Code:

sh-4.1$ set-focus 0x04000002
X Error of failed request:  BadWindow (invalid Window parameter)
  Major opcode of failed request:  42 (X_SetInputFocus)
  Resource id in failed request:  0x4000002
  Serial number of failed request:  7
  Current serial number in output stream:  7

The same thing worked fine with the image that I didn't dist-upgrade.
Does anybody have an idea? The easiest thing I can think of right now is that due to the upgrade of some C libraries set-focus doesn't work properly anymore. Unfortunately without the source code I can't even recompile it to verify that theory.

Edit:
This bug report might be helpful for understanding the general nature of the problem:

Right now I don't see how to adress the problem without debugging the set-focus source code.

Another edit:
Argh! Yes, there is a problem but it's less grave than I thought. The problem when switching from ED via Ctrl + Backspace is that somehow the Ctrl key gets stuck. Therefore if I return to ED pressing F in Leafpad doesn't write an "f" but opens the find dialogue. Even after closing this dialogue Ctrl is still stuck. And Ctrl + clicking window close X doesn't close windows (at least not in openbox). If I press (and release) Ctrl once after returning to ED everything is back to normal.
I guess the easiest solution would be to change the Ctrl + Backspace window switch action from key press events to release events. I'll try that, but first I need to get some sleep.

Good night everyone!
