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

Hi Kedar,
Over the last couple of weeks I have been working on beefing up
our kernel
to get a whole variety of devices up and running. One of my
primary
intentions while adopting fedora was to simplify the testing
and adoption of
these devices in various ongoing project. So far things have
been working
out great. We have had a good measure of success with devices
on the USB
host. We were quickly able to integrate a WLAN dongle, HID
devices and mass
storage.
Cool, this is great! :-)
The next challenge is a UI. I already have a framebuffer device
and a
touchscreen controller driver written and compiled into the
kernel. I have
never worked on any kind of UI systems or window managers and I
am pretty
much starting from scratch. Considering that, could you suggest
a set of
packages that I could use to build up a quick demo showcasing
the LCD and
the touchscreen.
We have managed to get the Gnome stack functional on the ARM board. Here is
a blog post that talks about that.

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:

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:

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.
Warm Regards,
Vijay Raju
Best,
Kedar.
