Have a chance to port Lucid on the EeeTop machine. There are some problems in touchscreen and resolution, and here is how to fix it.
1. touchscreen
In Lucid, evdev is the default driver for X input devices, but it's not useful for this type machine. So you need to install the "evtouch" driver, the package name is "xserver-xorg-input-evtouch".
aptitude install xserver-xorg-input-evtouch
Then you need to modify the default xorg.conf (create a new one under /etc/X11/), and below is the details.
--------------------------
Section "ServerLayout"
Identifier "Default Serverlayout"
Screen 0 "Default Screen" 0 0
InputDevice "Touch0"
EndSection
Section "Device"
Identifier "Configured Video Device"
Driver "intel"
Option "monitor-VGA" "VGA"
Option "monitor-VGA1" "VGA1"
Option "NoDCC"
Option "FramebufferCompression" "off"
EndSection
Section "InputDevice"
Identifier "Touch0"
Driver "evtouch"
Option "device" "/dev/input/evtouch"
Option "MinX" "1"
Option "MinY" "1"
Option "MaxX" "4096"
Option "MaxY" "4096"
Option "ReportingMode" "Raw"
Option "Emulate3Buttons" "false"
Option "Emulate3Timeout" "50"
Option "SendCoreEvents" "on"
Option "MoveLimit" "0"
EndSection
Section "Monitor"
Identifier "VGA"
ModeLine "1366x768" 85.600 1366 1430 1542 1798 768 771 777 795 +hsync +vsync
EndSection
Section "Monitor"
Identifier "VGA1"
ModeLine "1366x768" 85.600 1366 1430 1542 1798 768 771 777 795 +hsync +vsync
EndSection
Section "Monitor"
Identifier "Configured Monitor"
ModeLine "1366x768" 85.600 1366 1430 1542 1798 768 771 777 795 +hsync +vsync
EndSection
Section "Screen"
Identifier "Default Screen"
Monitor "Configured Monitor"
Device "Configured Video Device"
DefaultDepth 24
Subsection "Display"
Modes "1366x768"
EndSubsection
EndSection
--------------------------
And also need to add "69-touchscreen.rules" udev rule under /etc/udev/rules.d
notes: check sysfs by the command
udevadm info -ap /sys/class/input/event8
--------------------------
KERNEL=="event*", SUBSYSTEM=="input", ATTRS{idVendor}=="1bfd", ATTRS{idProduct}=="1688", SYMLINK+="input/evtouch"
--------------------------
BTW, explain how I have the right "ModeLine" parameters here.
We can use the "PowerStrip" tool (Windows tool) to have the values.
Below is the link to teach you how to get the right values by PowerStrip.

Have you been brave enough to try and get touch screen working on 12.04? I can't see any evtouch drivers, I'm worried I'll have to get my hands dirty compiling them myself and hope it works. Otherwise do you know of any other drivers that might work?
This is only a project that I have been used. As my remembering, the evtouch is the elder version and should move to evdev already. I think Ubuntu start to use "evdev" and "xinput-calibrator" packages to support multi-touch device. And it's all in apt format, so no need to worry about the compile stuff. If I have machine, I will have brave to give it a try~~~~ :)
