I have a relatively new Acer Aspire One 725, it contains the AMD graphics integrated chip as below..
Unfortunately I can't seem to find a compatible driver that unlocks the power of this device, I know it's quite beefy (comparitively speaking) as
tux@akira:~$ lspci -v | grep VGA
00:01.0 VGA compatible controller: Advanced Micro Devices [AMD] nee ATI Wrestler [Radeon HD 7290] (prog-if 00 [VGA controller])
running Steam a la Team Fortress 2 is possible (under Windows 7), though with 12.10 / 13.04 beta it's unbearable and unplayable.
Any ideas / suggestions? The latest Catalyst driver on 22nd of March didn't even recognise their own card :/
