: On runnin the vnc app, however i still get a series of "nxclient: retry
: connect attempt" followed by quit.
This means it isn't linked with the server. Check the vnc/Makefile entries,
to make sure they match other demo apps that are linked properly.
: 2. Allow screen updates to be done directly from within the VNC client.
: - The VNC client recieves pixel info from the server. The
: majority of the data written into the socket from the VNC client to the
: Nano-X server is Pixel information. If instead i can cut down on this
: transfer and have a frame buffer driver inside the VNC which would write the
: pixel data directly.....We would eliminate a huge time that is taken by the
: sockets.
Aaron has indicated most of the time is in the socket code. I don't
think this is just in the bulk data transfer. In any case, if you
want to use direct screen drawing, look at nanox/clientfb.c. Note
that your screen MUST match the incoming data format or you'll
have to convert it all yourself. (big task)
: again, i am not very well versed with the Nano-X architecture,
Read the Architecture doc on the web site.

tho i
: seem to be getting there thanks to some excellent help from out here. So any
: step i take would not be very well informed. So do come out with your
: ssuggestions.
: My objective is to eleiminate the socket layer. Either partially (Do away
: with pixel data transfer via sockets) or totally ( LINK_APP_INTO_SERVER)
: which doesnt "seem" to be quite right in the vncviewer.
