Update:

I now have my touchscreen working under XFree86 with my frugal hdd install.

First I checked the XFree86 log file (/var/log/XFree86.0.log) to see if X liked my configuration file and loaded the module for the touchscreen. It did.

I then double checked the hardware one more time to make sure that there was power to the touchscreen (it's a panel PC so it has LCD, touchscreen and cpuboard in one box).

After some research how to see what was transmitted on the serial port I tried:

"cat /dev/ttyS0"

Nothing happend. I tried with "cat dev/psaux" to see if the mouse transmitted anything while moving it - it did.

I tried the second serial port "cat /dev/ttyS1" and some garbled characters filled my screen when I touched it - the com-ports where switched. Argg

After changing my XFree86Config-4 file everything worked as expected.

Maybe this info can help some other poor soul in the future.

Best,
Peter

Below is my XF86Config-4 file.

I use Vesa and forced the screen resolution to fit the monitor. I got tricked by "default depth" from the start since I had it at 24 bits but the embedded graphic controller can only do 16 bit.

The MinX, MaxX etc parameters are there to "calibrate" the touchscreen.

Code Sample

Section "ServerLayout"

Screen 0 "Screen0" 0 0

I am trying to install the Penmount touch screen on a geode small board computer with a 512MB compact flash as the hard drive. I have not gotten it to work. My compact flashes stop working after I start configuring and installing the XF86. Do I only need to install the xfree86 dsl extension? DSL is installed to the hard drive. I would greatly appreciate any help.
Thanks,
Andrea

Hi,
I have a Geode system with a touchscreen (Penmount) that runs "successfully" on Fedora Core 3.

Having experimented with DSL on other computers I was wondering if it's possible to set up a touchscreen in the X server that DSL uses?

Thanks,
Peter
