Introduction

Asus launched a really nice gadget called the EeeTop ET1602 (There's also a ET1603, with a battery and an ATI video card, but that's for a premium).

LinuxMCE would run nicely on this thing, if it weren't for the screen turning off when X starts with the intel driver. Ironically, it works fine with the vesa driver.

The touchscreen works perfectly with the evtouch driver. The calibration data seems to be stored in the device itself, and the calibration utility is Windows-only, but it shouldn't need any refining unless you want pixel-perfect touching.

Configuring the touch screen

Install the evtouch driver

apt-get install xserver-xorg-input-evtouch

Configure udev

Configure udev so it creates a stable symlink. The /dev/input/eventX entry may change, so this symlink will be used to point to it Create the /etc/udev/rules.d/69-touchscreen.rules file with this content:

KERNEL=="event*", SUBSYSTEM=="input", ATTRS{idVendor}=="1bfd", ATTRS{idProduct}=="1688", SYMLINK+="input/evtouch"

Setup xorg.conf

My xorg.conf looks like this right now (The changes relevant to the Eee Top are in bold):

Finalize

• Reboot

You need to reboot so that udev creates the symlink properly. That, or you open up the EeeTop to disconnect and reconnect the USB port (if there is a USB header in there of course)

• Enjoy your touchscreen
