Things to do before and after Ubuntu Installation

1. harddisk is not recognised by Ubuntu Installer.

But you can mount the drive or the partition, and no problem to perform reads or writes

Ubuntu Installer can't find my SATA drive

2. Logitech Cordless Optical Keyboard

I just use "generic Logitech keyboard" and is just fine. The numeric keypads are working correctly. Don't select "Logitech cordless optical keyboard". My model is Y-RK49

3. install numlockx, and modify the X startup scripts, so that numlock is always ON when X windows is started

Enable Numlock Upom Login

4. fix the clock
As I am using same PC with multiple Operationg Systems installed, the real time clock is used differently.
Windows is thinking the realtime clock is local time, while in Ubuntu thinks it's UTC

so I change the Ubuntu /etc/default/rcS scripts to UTC=No

UbuntuTime

5 Make grub menu visible and with boot messages visible

grub2

it is located it /etc/default/grub
main changes are:

comment out GRUB_HIDDEN_TIMEOUT=0, by putting # at beginning of the line
GRUB_HIDDEN_TIMEOUT=5
GRUB_CMDLINE_LINUX_DEFAULT="nosplash verbose"

when done with the changes
sudo update-grub

6. Install the chinese fonts

install sun java6


7. Get the mp3 and other codecs.
Install the medibuntu
