I have a fujitsu lifebook b2610. It's a 10.4" XGA touchscreen. I've installed ubuntu on it and used X -configure to build my xorg.conf. Nowhere is the touchscreen mentioned, nor is it shown in lspci. I would like to assume it's an Elo touchscreen so that I can use the gentoo-wiki guide.

Question number two: how do I determine which serial port (which /dev/ttyS* ) is being used by the touch screen?

FcukThisGame,

Touch screen interfaces are normally serial or USB, so I would not expect to see it in lspci.
What does lsusb have to say about it, or look in /proc/bus/usb/devices ?
If its not there, I expect its serial.

If its serial, see if you can get gibberish in minicom by connecting to the first four serial ports in turn and dragging your finger over the screen.

I've found that the device is located at /dev/input/ts1.

I'm not sure what minicom is, but when i cat /dev/input/ts1, i do get gibberish. It's referenced as /dev/input/ts1 in my xorg.conf and it is working (although it needs calibrated terribly, and it worked fine when it was listed as /dev/ttyS0, although there was no output when i would cat it.

FcukThisGame,

minicom is a terminal emulator program. It allows you to communicate with serial devices at a very low level.

I've been doing some research into calibrating the touch screen... and all I really found was called 'touchcal' and it didn't work if I specified /dev/input/ts1.

is there a better way to do so?
And better yet, is there a correlation of the {x/y}{min/max} to the screen's resolution?

FcukThisGame,

If you can discover where the calibration constants are stored, you can change them by hand.
Its not difficult with a little trial and error. I've done it on an iPaq after really messing it up.
