Kernel 3.12-rc1 is here

[VinDSL]

While we're waiting for the nvidia driver to be patched to work with 3.12-rcN I thought I'd try switching to nouveau because I haven't used it before.[...]

Seems to be working nicely.

Good to hear!

The trick, if you will, is to keep the llvmpipe driver from loading. llvm is hideously slow and choppy on this rig.

That aside, Nouveau works great, albeit a little warmer. GPU runs +10C on this machine, Nouveau vs. nVidia.

Hi Vin,

I'm not familiar with llvmpipe. That module doesn't seem to be loaded on my box. Something to do with Unity? Too late for me to look into it right now, but I'm just using a text login to fluxbox. Have various other modules blacklisted. Can't get much leaner without compiling my own kernel. Lol.

Hi Paul,

The only time I've had llvmpipe crop up, is when I forget to check my '/etc/modprobe.d/' conf files, to see if nouveau is blacklisted.


Example(s):

Nouveau Blacklisted

OpenGL vendor string:   VMware, Inc.
OpenGL renderer string: Gallium 0.4 on llvmpipe (LLVM 3.2, 128 bits)
OpenGL version string:  2.1 Mesa 9.2.0

Nouveau Enabled

OpenGL vendor string:   nouveau
OpenGL renderer string: Gallium 0.4 on NV4B
OpenGL version string:  2.1 Mesa 9.2.0

My modprobe is clean, right now...

vindsl@Zuul:~$ cat /etc/modprobe.d/* | grep -H 'blacklist nouveau'
