Problem while installing amd driver on ubuntu 12.10 on my dell inspiron 5520

Question

I have a dell inspiron 5520 which has switchable graphics mode with amd radeon hd 7600m. I have recently installed ubuntu 12.10 alongside windows. But i can't install the driver for grahics card. While typing "sudo apt-get install fglrx-installer" it says unable to locate the package. While adding the repository ubuntu-x-swat/x-updates it shows error that

"The requested URL /ubuntu-x-swat/x-updates/ubuntu/dists/quantal/main/binary-         i386/Packages was not found on this server."

In another attempt i download driver from amd-driver site, and then installing from terminal it shows that some errors come while installing and I get the blank screen only.

So how to install the amd driver on my laptop.

Answer 1

I had what seems to be the same issue. The AMD driver needs to be downgraded. Follow the steps here: http://www.ubuntugeek.com/how-to-install-amd-catalyst-legacy-drivers-in-ubuntu-12-10-quantal.html

This will install the legacy driver which may (if it is the same problem) bring things back to full resolution again.

Answer 2

Did you try update? I had Dell Inspiron N5030 two years ago and I had a problem with graphic cards driver... I updated my system, rebooted and it was OK.
