Wow thanks for the info. That will make things a a lot easier to
understand.


I made some progress yesterday. I got my wireless network set up and
used ssh to log in and install xorg. I still couldn't get the lcd to
turn on so I dumped the original script.bin and the one from the debian
image and compared them. I ended up changing a few lines and was able
to get the lcd to turn on:

screen0_output_type = 3 TO screen0_output_type = 1
lcd_pwm_pol = 0 TO lcd_pwm_pol = 1
tvout_used = 1 TO tvout_used = 0

Now when I run startx, I get a console and a cursor :)

I also enabled the touchscreen parameters in script.bin and loaded the
ft5x_ts module. Unfortunately its still unresponsive. I will have to
look through the source to see if I can figure out whats going on.
