Hi mate ..

I'm working on the same lines .. will keep you posted.  Forget about anyone
from the vendor coming back to you with anything useful, they are a bunch
of lazy tossers IMHO.

I must say though, and this is for everyone in the forum and the people who
made the FriendlyARM series, that much as I love the board, much as I am
disgusted about the complete lack of documentation and outright broken code
in so many aspects.  And what's there and shipped is so poorly written,
badly formated, ill-translated, outdated and outright useless.

Just because you ship the board with old, lame and completely useless
images of Qtopia and Windoze CE doesn't make this a complete development
chain. Oh, and did I say seg-faulting and crashing the hardware all the
time? non-functioning u-boot source and binaries that you have to struggle
to get on the board?

I've gone my own way, compiled a working 2.6.39.x kernel from scratch,
integrated the drivers, got Buildroot 2011.05 working, barebox compiled and
working, and fixed a million annoyances and broken code on the way.

I'll publish all of this once I get Xfb (my last challenge) and something
like MatchBox working properly.

No thanks or credit due to anyone from the vendor side.

Bah Humbug !!

Start your X server, setup the DISPLAY=:0.0 environment variable and start
the application you want (from inside a second shell). Or take a look into
the "startx" shell script, how to do it automatically.

Not working :(

Test QT4 application still doesn't launch without -qws option.

QWSSocket::connectToLocalFile could not connect:: No such file or directory

I guess your Qt lib is not built/linked against the X libs. So, they will
not collaborate with a running X server. You should run your application
with the "strace" tool, to get an idea what is going wrong with your X lib
based application.
