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

Add your Eee Top as an MD

Connect your Eee Top to the LAN side of your Core (set it for PXE boot in BIOS first of course) and power it up. The Eee Top should start to PXE boot and you will see the following yellow text on screen - "We have announced ourselves to the Router..." and you should see that the script "DisklessSetup.sh" is running. This stage will take some time... be patient. The Eee Top will then reboot and continue the setup process. After a few mins the Eee Top will be sitting there in the AVwizard... with a blank screen. Now we are ready to continue onto the next step...

Use Web Admin to identify the ID of your Eee Top

Go to Web Admin on your Core and then to Wizard -> Devices -> Media Directors and scroll down to the bottom of the page. The last Media Director listed will be your recently added Eee Top. Make a note of the number with a '#' in front of it next to the drop down that is used to select the room the MD should be in. This number is the 'Moon' number or unique ID of the MD.

SSH into your Eee Top

Go to your Core (or ssh into your Core from another computer, open a Konsole window and sudo yourself;

sudo su -

chroot yourself to the Eee Top

Use chroot to gain access to your Eee Top so that we can make the changes in the following steps;

chroot /usr/pluto/diskless/<Moon No. from above step>

Your prompt should change and you are now working on the Eee Top's file system.

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
