Hi Kedar,

After a lot of playing around with X I finally gave up and switched to Qt. I
finally got the display to work with the touchscreen yesterday.

Attached is a picture of the test setup and our hardware platform. Thanks
for all the help.

Warm Regards,
Vijay Raju

Cool, this is great! :-)

We have managed to get the Gnome stack functional on the ARM board. Here is
a blog post that talks about that.
http://fedora-arm.blogspot.com/2009/07/fedora-arm-goes-graphical.html

You have to install the X and the Gnome package groups from the
repositories. I suppose there are a couple of packages missing from the
group, you might have to skip them manually (These are already built, just
that they haven't hit the externally published repositories yet.) A detailed
listed of steps is available here:

l


Once that is done you should be able to get the X going. There were a few
other problems seen when we installed a system this large a size. These are
documented in here:
http://fedora-arm.blogspot.com/2009/07/dhclient-firstboot-and-hald-woes.html


I haven't given a shot to the touch-screen interfaces though. If you are
looking for any set(s) of packages for the purpose, that aren't still in
there, do let me know.
