Radeon X1550 or RV505

I got six new computers which specifications are :

MB : MSI K9AGM3-FIH ( sound : Azalia / ALC888 )
VGA : GigaByte GV-RX155128D-RH ( RV505 )
Proc : AMD Athlon64 X2 4800+
RAM : V-GEN 1GB
HD : Seagate SATA 80GB

Installing Edubuntu Gutsy Gibbons on this unit need an extra patient and search, since i can not find the driver for the display which identified as RV505. I also can not find the driver on ATI driver site. After some times.....here is the way !

If you are trying to install Hardy,
the installation will be flawlessly
you just need to Enable ATI in Hardware Drivers
( previously recognized as Restricted Drivers )
xorg-driver-fglrx will automatically installed
finish the process by reboot
then install compiz....set it....run it

First of all; boot from Edubuntu liveCD and when the installation menu appears; press F6 and it will display Boot Options command like;

file=/cdrom/preseed/edubuntu.seed boot=casper/initrd.gz quiet splash -- 

erase "quiet splash --" by pressing backspace button, so it became;

file=/cdrom/preseed/edubuntu.seed boot=casper/initrd.gz

then press enter

The processes will run and will end up with no GUI but a blue screen with a log info printed out
press OK and then you will see the screen displayed something like :

..
..
* Running local boot scripts (/etc/rc.local)

and with the cursor keeps blinking

then press ctrl+F2 to bring you to the prompt to type

sudo dpkg-reconfigure -phigh xserver-xorg

choose vesa then ok
choose the screen resolution then ok

the monitor will blink again for a while and bring you to login window.....just let it login in 10seconds automatically (if you are back to the prompt, type startx , later on you will be asked to press ctrl+F7 for the default GUI )

Now you can install edubuntu

When the installation finished, restart the computer and login to edubuntu.

We have to update the system
1. go to system - administration - software sources
2. after that close it and reload it
3. update the system from system - administration - update manager

Then we can work with the display ( still vesa now ) to activate compiz
1. go to system - administration - restricted drivers manager
2. enable the ATI accelerated graphic driver
3. it will automatically download xorg-driver-fglrx
4. open terminal ( applications - accessories - terminal )
5. type sudo gedit /etc/X11/xorg.conf
6. Find Section "Extensions", change "Composite" "0" to "Composite" "1"
7. save and exit the editor ( ctrl+s and ctrl+q )
8. still in terminal, type sudo apt-get install xserver-xgl
9. then type sudo apt-get install compizconfig-settings-manager
10. then sudo reboot
11. after reboot, go to system - preferences - appearance
12. go to visual effects tab
13. change to custom ( it will blink and done.....you can choose it now )
14. click preferences to set the compiz effects
15. finish
