so i search and found two ways to solve that

first
"sudo gksudo gedit /etc/rc.local "
and add "setpci -s 00:02.0 F4.B-0 "  before  EXIT 0

and the result was black screen

second way work for me it was the nomodeset

sudo gedit /etc/default/grub
and edit that
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
with that
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash nomodeset"
or
GRUB_CMDLINE_LINUX_DEFAULT="nomodeset quiet splash "

 I would make sure you are using the most up to date proprietary driver for your HD 5470. If you are not sure how to do get it check this out. http://ubuntuforum.webs.com/proprietarydrivers.htm (http://ubuntuforum.webs.com/proprietarydrivers.htm)

So, I have the same problem, because I update Ubuntu 11.04 to 11.10. I can not install a driver for my ATI 5470.  For, debian, OpenSuse, Fedore I can not install driver. After installed is Black Screen but when I clean xorg.conf, system can start but, I don't use full of possibilities my card ;/ I look for Internet but, I can not find solutions for my problem.
I have notebook HP G72 with ATI HD 5470 and Intel graphics. I don't speak in english very well, Sorry for mistakes.

or u download the latest driver from ati.com and install it from terminal
u say when u clean xorg.conf, system can start

I install in terminall, I download lastest driver form ati.com. After install I reboot my Notebook and I see Black Screen. I can not install driver on any Linux, after install I have always Black Screen. Now I have a debian bacause it supports 1600x900 but I don't can also install driver ATI. I don't know what I am now doing :(

What is the reason? May be dual Graphics ?

Hi!

Your following suggestion needed just a small modification after which it worked like a charm and solved the problem

"sudo gksudo gedit /etc/rc.local "
and add "setpci -s 00:02.0 F4.B-0 "  before  EXIT 0

as follows
"sudo gedit /etc/rc.local "
and add "setpci -s 00:02.0 F4.B-0 "  before  EXIT 0

As you can see above, I have just removed "gksudo", saved the modified file and restarted the computer. There was no more black screen problem. Boot process was perfect and it stopped at "User ID and password" entry with a brilliant white screen, just a perfect one.

I must just precise that I have had exactly same problem as you have had with the exception that my laptop is Acer 7715Z. I hope that this solution will work for any laptop with which one has the same problem.
