I'm facing a problem while installing an ATI driver through ADDITIONAL DRIVER. I was trying to install the same in Ubuntu 13.04.

The config of my laptop is AMD Radeon HD 7640G/7670M Dual GPU (1 GB DDR3 dedicated)

I'm facing a tough time ahead my project due to this issue. I have tried almost everything available in net.

tried following the instruction given in unofficial AMD site ... but of no avail.

Now though I have UBUNTU 13.04 installed perfecly on my lappy.... The charge gets drained out in matter of just 15 minutes.

Also while booting ubuntu i get following error ERROR: CANNOT FIND A BACKLIGHT CONTROLLER before i enter my password...

Please Help..

I switched over to Ubuntu 14.04 and installed the latest ATI graphics driver from AMD site and it is working fine now. Thanks to dazed_n_confused.
