[maemo-developers] x11vnc no response to taps on left of screen

Hi Jeff,

For the Python question, all you need is the 'xterm' package. It's called
OssoXterm or something. I don't have the URL, but it was real easy to find
on the maemo site. I've reflashed my N800 3 times and found it there (not
reflashing due to problems.. testing ported software on it).

I get the same problem as you with the x11vnc not responding to clicks on
the docking/application bar. It's frustrating as heck because it was
inversely so neat to even find a vnc server for this. It is definately an
x11vnc issue as I tried 2 different VNC viewers, and if I maximize
applications I can still register clicks in that area.

If x11vnc worked 100%, it would be VERY useful. For example, my LInux
desktop machine can save VNC sessions to a file, and convert them to AVI,
which is much more powerful for end users than simple screenshots. I'm
looking forward to a solution for this also.
