AMD has recently dropped support for cards in series HD 2xxx-4xxx. Catalyst drivers for these cards are now available in a different branch, called Legacy series. Legacy drivers won't receive any new feature updates from AMD.
Proprietary fglrx drivers for these legacy cards are not compatible with Quantal.
I have a Acer Aspire V5-552G laptop that comes with two AMD graphics cards(APU + a dedicated one). I have installed the proprietary fglrx-updates drivers, but the drivers are old. They don't even include the switch graphics option to switch between the two graphics cards. What can I do to get the new amd omega drivers?
