eeepc, touchscreen and evtouch

I've got an eeepc 701. It seems that part of the process of owning one means that you're obliged to pimp it in some way. A buddy of mine added a blue tooth module, but I thought it'd be cool to add a touch screen.

Scratching around on Ebay, I managed to find one from VirtualVillage, ordered, waited, received, experimented and installed. It ran on WinXP after a quick install, so I thought it'd be easy enough to run under Debian. After ruining my install of Debian through a combination of ignorance and clumsy attempts to compile and install the eGalax driver provided, I reinstalled and started again. Ultimately, a stock standard install of the evtouch driver, with a few pretty much undocumented options in my xorg.conf file made everything okay.

Getting there was a bit of a pain though. I found an obscure URL http://www.postnuklear.de/xorg-patches/ after googling a bit, saw that it was an unofficial patch, googled a bit more, and it seemed like the patch had been rolled into the evtouch driver. I just added a few extra options to xorg.conf, and they seemed to work. So we basically have undocumented features in the evtouch driver. Great.

Here's the /etc/X11/xorg.conf file for future reference:

# xorg.conf (X.Org X Window System server configuration file)
#
# This file was generated by dexconf, the Debian X Configuration tool, using
# values from the debconf database.

# Edit this file with caution, and see the xorg.conf manual page.
# (Type "man xorg.conf" at the shell prompt.)

# This file is automatically updated on xserver-xorg package upgrades *only*
