black and white checkers on startup- radeon 9600 ubuntu 9.04 problem

[soundpete]

I had this problem the other day, black and white checkers after ubuntu 9.04 boots up(from hard drive) . Once it occurs nothing can be operated in the ubuntu desktop.

It is not a hardware fault because I stuck the 9.04 cd in and switched it to boot from cd in bios and it worked fine.

So I reinstalled the OS and everything worked fine, the only piece of software I remember installing is the ATI catylist control centre, as I have a ati radeon 9600 graphics card, and upon reboot I get the black and white checkers again.

Im thinking of changing to a different os as I think 9.04 doesnt like radeon 9600.

Seriously annoying.
Any Ideas??????????????????????????

I have a Radeon X1900 GT, and when I installed the Catalyst Center, it fragged mine too. The ATi driver off of ATi's website should help. If you find a way to uninstall Catalyst, do it. If not, you may have to reload Ubuntu. After it's back up, get the driver off of ATi's website and run it through the terminal. At the end, it will have a command that it says to type into a terminal if Ubuntu doesn't come back up graphically after rebooting. Write it down, because you may need it. Hope that helped!

x**** series or older don't work on 9.04 becuause ati's latest drivers do not support them and ubuntu is released with the latest at the time.
you could use 8.10 which will support them
