xserver-xorg-input-dmc FIT-10 configuration/setup
Hello List.
I know, this is no support-list but it seems there is no other way to contact the developer or maintainer of xserver-xorg-input-dmc. I try to set up a touchscreen with FIT-10 chipset for nearly two months by now with no success, due to there's really _NO_ documentation about this driver. The man-page is nearly empty and says "THIS MAN PAGE NEEDS TO BE FILLED IN.", although the package with version-number " 1:1.1.1-3" is listed as stable. Extensive google-work also helped nothing - it seems noone set up a touchscreen with FIT-10 before. If you have better proposals to get information about it, please let me know. I will instantly stop bothering you. ;)
My configuration:
- Debian Testing (Lenny) with X-Server from Unstable (version 1:7.2-5, works fine)
- xserver-xorg-input-dmc from Unstable (version 1:1.1.1-3)
The FIT-10 works well in Windoze on "Com3". In Linux this should be
"serial8250: ttyS2 at I/O 0x3e8 (irq = 4) is a 16550A" according to the irq and i/o.

What I did:
- tried all four tty-devices
- extensively googled for a xorg.conf matching the problem
- looked everywhere for documentation (I even got the sourcecode hoping to find information)
- looked for developper-websites or mail-adresses of the author (even in the manpage, noone is mentioned. Seems that some ghost wrote that code...)
Whats the problem:
- no interaction with the touchscreen
- options of the driver are undocumented
- don't know where I should start debugging
Its a bit funny that such a very bad documented driver made it's way into all major distributions... I feel like I'm the only person on earth to try it the first time... It would be a pity, if I couldn't get it working 'cause i could get a lot of those 10" TFTs with that touchscreen-controller. And in fact I don't see any reason why it souldn't work.
I use Linux for four years by now. You could guess how hard it was for me to contact a developper-list with a support-related problem. But I don't see any other way to find information about it. If there's someone out there who can help me and I get it up and running, I will document all steps very well and make it public, so that the ideas of OpenSource and OpenMind are fulfilled again. :)
Greetings,
Felix Wiedemann
