I am newbie to Ubuntu.
I want update my opensource Radeon driver to latest one, because comparatively to proprietary driver, opensource one is lagging behind according to benchmarks at here. Although It is so, I like to stay with opensource driver, But I want keep it up-to date to get better video driver performance.
So where can I find the latest opensource driver and how to install it?
Most of the open source Radeon driver is part of the Linux kernel, so you need to update that in order to get the latest version. On Ubuntu, you can use the the update manager to do so, although the Ubuntu repositories will not always have the latest version, so you will need to add an additional repository. If you want the very latest version, you'll need to download the tarball from kernel.org and compiling it yourself. (Not adviseable for newbies IMO !)
You should also update the xserver-xorg-video-ati and xserver-xorg-video-radeon packages, and possibly others.
Beware that:
Depending on your hardware and / or Ubuntu version, may not give you much, if any, performance improvents, since the drivers are already pretty optimized.
