Can someone please tell me how to download a driver to fix ubuntu 11.10 graphic driver problem (Radeon HD 6470) if I cant boot Ubuntu. I cannot set to acces with graphic commands so I am hoping I can download and run the driver to fix. Thanks for any help Tony

Thanks everybody for the suggestions I think I should give some further infomation. I think loading latest driver would be worth trying however from my login can someone explain if for instance I were to download the latest driver what command is needed to fetch the driver from say a pendrive? Also I ran STARTX and had a report 'Failed to load fgirx (module does not exist,0) is that relevant. Sound like its worth a try to install latest linux driver from ATI but can someone give me the commands to use to get to pendrive and run from my antony@antony-305V4A-305V4A:etc

Or how to move the driver on pendrive to home folder?etc.

Note: If I try to run sudo apt-get install fglrx -installer......it tells me unable to locate fglrx -installer

if I write
sudo mount -t vfat /dev/sdb /mnt (where sdb is the flash) I get FAT-fs (sdb): bogus number on reserved sectors mount: wrong fs type, bad option, bad superblock on /dev/sdb, missing codepage or helper program, or other error. Have formatted the flash to Fat and again copied driver on. Need to update ati driver as cannot boot 11.10 Any ideas thanks

By the laptop model you specify, I almost guarantee you are using a SAMSUNG laptop with an AMD APU, Oneiric has a bug that is only fixed with the last kernel update (which I think it was 3.0.0-16-generic).

In order to get it working under the A4, A6, or A8 APU, out of the box, download a minimal iso from Ubuntu, make a install, and it should be working.

You can get the minimal iso from here:
Ubuntu Minimal CD

Why minimal CD?

The Minimal CD will download packages from online archives at installation time instead of providing them on the install CD itself. Only current packages are downloaded, so there is no need to upgrade packages immediately after installation. The Minimal CD uses a text-based installer like the Alternate CD, making the CD image as compact as possible.

Which in other words, means you will be getting the lastest kernel at install.

It is a known bug in Oneiric not supporting the APUs properly, which you can review here:

#825777 Display will not turn on in Oneiric with Llano APUs

HDMI should be working, so try using if you still get your screen turned-off. For what I know, VGA should not work without fglrx, only HDMI.

Or either, I think bug is already fixed on Precise Alpha 2. (If you have an A4 APU ONLY).

It is also a known bug that you might get "Wireless Device not Managed", in most cases, with the Atheros Wireless some SAMSUNG laptops ship with, which you can review here:

#929969 Atheros Wireless "device not managed"

A workaround for this instance is setting your wifi connection from the text-installer, (which is default on the minimal CD for 11.10, or the alternate-text-installer for 12.04 in case you have an A4.)

Either that or connecting to a wifi from the terminal.

If you get any issues, don't forget to ask.
Good luck! ;)
