How to change the "indicator" default setting, like mail agent

There is no setting option in gconf-editor or panel properties.
But you can just use the file to change the preferred application.

- In /usr/share/indicators/messages/applications/ there are some files, like empathy/evolution/gwibber in my folder by default.
- You can add a "thunderbird" file.
- And add a line in it as "/usr/share/applications/thunderbird.desktop".
- Then~~~you will see the indicator show you "Mozilla Thunderbird" dynamically.

Enable/Calibrate touch screen on EeeTop ET1602 for Ubuntu 10.04 (Lucid)

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.

Monitor "Configured Monitor"
Device "Configured Video Device"

--------------------------

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.
