From where to get the latest (pre-builded) open source drivers?
Hi, I have been searching but didn't find any guide or something in order to obtain the latest open source drivers.

What I have now :
OpenGL vendor string: VMware, Inc.
OpenGL renderer string: Gallium 0.4 on llvmpipe (LLVM 3.3, 128 bits)
OpenGL version string: 2.1 Mesa 9.2.1
OpenGL shading language version string: 1.30
OpenGL extensions:

Linux Mint 16 KDE, kernel 3.11 (Ubuntu saucy)
AMD A6 - HD8400

Thanks in advance.

sudo apt-get update
sudo apt-get dist-upgrade

One more thing: Dynamic power management is not enabled by default yet with kernel 3.11. You can do this manually by adding "radeon.dpm=1" to your kernel boot parameters. In the "/etc/default/grub" file, you should add it to the "GRUB_CMDLINE_LINUX_DEFAULT" line. It should look similar to this when you're done:
GRUB_CMDLINE_LINUX_DEFAULT="quiet radeon.dpm=1"

After that, do an "update-grub" and reboot. Without enabling dynamic power management, your APU will default to its lowest clock. DPM gives you a nice performance bump. On newer kernels, it's enabled by default.

Sorry, I don't use KDE myself. How bad are the glitches? That PPA you're using is usually stable, but somtimes bugs will make their way into it because it's pretty cutting edge code. There is a pretty long thread about the oibaf ppa on the Phoronix forums, so it might help to browse through that.
