Recently I bought an Acer Aspire One 725 Netbook and installed Ubuntu 12.10 on it. I bought it, because it can run HD movies and has Full HD on external VGA port.

However, movies from youtube have a really slow framerate. If you open three tabs in Opera (for example g-mail, youtube and askubuntu) it gets really laggy.

My suspicion is that the driver for graphic card is missing. When I check the System->Details->Graphics the driver is unknown.

After running lspci | grep VGA I get this output:

00:01.0 VGA compatible controller: Advanced Micro Devices [AMD] nee ATI Device 980a

From what I see, I have a AMD C70 processor integrated with AMD Radeon HD 7290.

Has anyone had the same problem? Do you know which drivers need to be installed for the graphics to work properly? On official Acer page there are only drivers for Win7 and Win8...

Update: OK. Another attempt. I have a fresh Ubuntu 12.10. All updates done. downloaded Catalyst 12.11 beta drivers and decided to create a package. After installing package, I have this error from /var/log/Xorg.0.log:
