BEST idea for getting all needed dependencies is to use command that will install development dependencies for given package. Oh howto there should be so example for it.
If you do not know how, than you can still try to find source package for mesa, and read dependencies and install them manually. (Did so on fedora!)
EDIT:
For ubuntu it should be:
sudo apt-get build-dep <package>
Change <package> for EVERY package starting with mesa in your system.Last edited by przemoli; 03 March 2013, 04:08 AM.

ok, so I installed the xorg-edgers packages for Ubuntu as an easy way to update the kernal and get an updated version of libdrm. I was then able to build the version of mesa from the repo. I setup the environment variables, etc, based on the radeon Build guide, rebooted and found I could not log into Unity as every time I tried lightdm seemed to restart itself. I managed to log into Gnome classic and read the "Configuring system to load mesa and libdrm from /opt/xorg" instructions again an noticed that I needed to build with the --enable-glx-tls switch. I rebuilt and installed and this time I could log into Unity however (and this was happening in Gnome without the --enable-glx-tls switch too) when I try to load any OpenGL application lightdm is resetting itself.
Any ideas what logs I should be looking at or what might be going wrong?

Thanks, przemoli
For anyone else looking the repo is can be found here: http://cgit.freedesktop.org/~vadimg/mesa/log/?h=r600-sb
The dev has only tested with evergreen so test it out and let him know what you find it would be great to get this merged.

I'm a developer so I'm not a complete noob but I've never ventured to these deeps of the OS before.
Edit: By the way I'm currently using Ubuntu 12.10 on the laptop I would like to test with but can use something else if this will mean its easier to do.
(And such testing is semi secure. Unless you GPU melt you can revert everyghting in console (which equal to changing 2 lines of config and removing one directory, go read radeon build how to)
For such speed up I'm going to test it right now!

@timothyja
It's mesa only, and you can test that without installing anything. Build mesa, and run this from the main dir
LD_LIBRARY_PATH=lib LIBGL_DRIVERS_PATH=lib/dri myapp

From the mailing list:
Heaven 3.0, all settings high/enabled, 1280x720, HD5750:
default backend : 20.0 fps
llvm backend : 18.8 fps
r600-sb : 38.0 fps
I didn't see this coming. If they don't merge it, distributions will.
