HOW TO: Install experimental X.Org and the latest graphics drivers

[schnelle]

I found one more ppa with latest stable releases of drivers (not from git, only bugfix releases): https://launchpad.net/~glasen/+archive/intel-driver

but how dose one tell whether gallium llvmpipe is being used as default or not?
as (and I quote) "* gallium llvmpipe as the default software renderer rather than classic swrast"... it seas it dose ??

I'm curious about this too. I wanted to run some tests to see if one performed with opengl better.

You could "trick" glxinfo into spitting out some details while avoiding long lists of extensions and visuals:

steve@x1:~$ [B]glxinfo |grep ': '[/B]
name of display: :0
display: :0  screen: 0
direct rendering: Yes
server glx vendor string: SGI
server glx version string: 1.4
client glx vendor string: Mesa Project and SGI
client glx version string: 1.4
GLX version: 1.4
OpenGL vendor string: Intel Open Source Technology Center
OpenGL renderer string: Mesa DRI Intel(R) Sandybridge Mobile 
OpenGL version string: 3.0 Mesa 8.1-devel
OpenGL shading language version string: 1.30

steve@x1:~$ [B]LIBGL_ALWAYS_SOFTWARE=1 glxinfo |grep ': '[/B]
name of display: :0
display: :0  screen: 0
direct rendering: Yes
server glx vendor string: SGI
server glx version string: 1.4
client glx vendor string: Mesa Project and SGI
client glx version string: 1.4
GLX version: 1.4
OpenGL vendor string: VMware, Inc.
OpenGL renderer string: Gallium 0.4 on llvmpipe (LLVM 0x301)
OpenGL version string: 2.1 Mesa 8.1-devel
OpenGL shading language version string: 1.20

If you configure that environment variable at boot, I'd imagine that all OpenGL would use LLVM.

and how would one go about that ?
currently I put a shell script in start up and that dose not seem to do it ...or adding it to the grub boot line

Latest update - kernel 3.5.0-10 - breaks nfs. booting back to -9 solved it for now.

UPDATE: It appears the problem I was having was my server is using NFSv3 and the latest update moved fstab mounting to NFSv4 or somehow changed the setup of NFS. Adding "vers=3" to fstab fixed it.
