In the last few days, I choose to upgrade my Asus EEEPC 900 to EEEBUNTU NBR 3.0 (based on Ubuntu 9.04 Desktop Jaunty).
After the installation, it was unbelievable how it worked badly...
The mouse pointer was tilting (as the mouse ball was unclean since 1990... Amiga like style!)...
Anyway all the system was very very very SLOOOOWWWWWWwwwww.
Oh My God!!!!!
Well, the solution was behind the corner... as far as 2-3 hours of googling!!! (Sigh!) Here it is!!!
The problem was the EEEPC 900 i915 video card related to the driver included into Jaunty!

Here we go... The solution!!!
It was Very Very simple! I need to revert to 2.4 Intel driver according to https://wiki.ubuntu.com/ReinhardTartler/X/RevertingIntelDriverTo2.4 !
How to... Step by step!
Press Alt+F2 and write xterm then the following:
1) sudo su (...and insert your password)
2) vi /etc/apt/sources.list
3) (copy&paste the following into the file, than press ESC key and write :wq)
deb http://ppa.launchpad.net/siretart/ppa/ubuntu jaunty main
deb-src http://ppa.launchpad.net/siretart/ppa/ubuntu jaunty main
4) sudo apt-key adv --recv-keys --keyserver keyserver.ubuntu.com 0xce90d8983e731f79
5) sudo apt-get update && sudo apt-get install xserver-xorg-video-intel-2.4
Reboot the system! (you can write reboot into the console)
Before rebooting upgrade to 2.6.29-1 Kernel by typing:
apt-get install linux-headers-2.6.29-1-netbook linux-image-2.6.29-1-netbook
Anyway If you need some help, write me! :)
