One problem I faced with my Asus EeePC 1101HA was adjusting the screen resolution. Things would appear really stretched when I installed Ubuntu 11.04. The Display option would have only one option for me (4:3). A little research on the topic and I found the following commands to actually install the Intel EMGD drivers which would give me enough options to choose from:
sudo add-apt-repository ppa:gma500/emgd
sudo apt-get update
sudo apt-get install xorg-emgd emgd-dkms emgd-xorg-conf
Run these codes one after another and then reboot to changes take effect. Now go to
System -> Monitors
You would be able to see all the available options for the monitor configuration.
