1. The input related stuff has not changed -- so it should be used the same way as it was in 6.3.x.

2. Take a look at this docs: http://www.qnx.com/developers/docs/6.5.0/topic/com.qnx.doc.neutrino_utilities/d/dispconf.
html
This is the utility that is used to create/update the default display.conf file when a self hosted x86 is started.The 
enumerator (enum-devices) uses it. The default display section for your device looks like this:

display {
   xres=640
   yres=480
   refresh=60
   pixel_format=rgb565
   photon {
       enabled=1    # if this is the primary display card.
       xoffset=0
       yoffset=0
       cursor=hardware
       input_group=1
   }
}

You will need to modify it to reflect your graphics parameters. Most importantly the 'cursor=hardware' should be changed
 to 'cursor=none' --> this is your '-photon touchsceen' equivalent.

3. The graphics start up would be similar to this:
    io-display -d vid=...,did,...
    io-graphics -n /net/MCC/dev/photon

I didn't use '-d vid...' with the io-graphics, because there is only one device, and it should be detected automatically
.

4. The '-F-A' -- you need to modify the /usr/photon/font_repository/fontopts file and add the '-A' option' to the [io-
font] section. See phfont docs for details: http://www.qnx.com/developers/docs/6.5.0/topic/com.qnx.doc.

Thanks for the help. Unfortunately, there's still something missing.

I used dispconf to update my display.conf file and found the following at the beginning of the file (I manually changed 
'cursor=hardware' to 'cursor=none'). Everything seems reasonable to me but I don't really know exactly what I'm looking 
at.

device {
        photon {
                driver {
                        drivername=i830
                        modeopts=
                }
        }
        drivername=i830
        modeopts=
        vid=0x8086
        did=0x3582
        deviceindex=0x0
        display {
                xres=800
                yres=600
                refresh=60
                pixel_format=argb8888
                photon {
                        enabled=1
                        xoffset=0
                        yoffset=0
                        cursor=none
                        input_group=1
                }
        }
}


On my peripheral, the machine with the touch screen, I attempted to run:

io-display -d vid=0x8086,did=0x3582,deviceindex=0
io-hid -dps2ser ps2mouse:mousedev &
devi-hid -P -r mouse
io-graphics -v -n /net/MCC/dev/photon
devi-elo ....

Unfortunately, I'm getting the following error on the touch screen

Could not initialize device "vid=0x8086,did=0x3582,deviceindex=0": No such file or directory
io-display failed to initialize

Must the graphics framework, io-display, run on both the server that's running Photon and the peripheral with the touch 
screen?

That's what I have running now, two instances of io-display, but that seems counter intuitive since the io-display 
documentation says it should be started before Photon. In all likelihood, Photon will have started on our server machine
 before io-display is started on the peripheral computer with the touch screen.
