The log is saying that there is something wrong with your /etc/X11/xorg.conf. Maybe some typos or made some mistakes while copying some text?

Thanks for tips! I solved my problem and it works perfectly!

Your solution is very good for vanilla -rt kernels that didn't function with nvidia proprietary drivers.

But, as in my previous post I said, I encountered some errors in phase of compiling drivers 2d & 3d.
The problems were due at the location of headers and sources of my vanilla kernel (in a folder placed in my home dir).
After solved this, (I copied all elements of headers folder in sources folder with the union of files), the problem was the command in point 4 of section "E" of your "how-to".
With your command (probably for old version of git mesa driver), the system does not compile "nouveau_dri.so".

So, I used this command:

./autogen.sh --with-dri-drivers= --with-gallium-drivers=swrast,nouveau --enable-debug \
 --enable-texture-float --disable-asm --enable-opengl --disable-gles2 --disable-openvg \
 --enable-dri --enable-glx --enable-xvmc --disable-va --disable-vdpau --disable-osmesa \
 --disable-egl --disable-xorg --disable-d3d1x --disable-xa --disable-gbm --disable-xlib-glx \
 --disable-gallium-egl --disable-gallium-gbm --disable-gallium-llvm --disable-xcb \
 --enable-driglx-direct --enable-glx-tls --enable-glu --enable-glw --disable-motif PKG_CONFIG_PATH=/lib/pkgconfig

as I found here http://nouveau.freedesktop.org/wiki/GalliumHowto

And then I ran:

make PKG_CONFIG_PATH=/lib/pkgconfig

After this, I re-took your points.

My last problem was the Xorg configuration.
I resumed an old backup of my Xorg, I insert "nouveau" in "Driver" and some data for change the resolution of my laptop display.
When I'll come back to my home, I'll paste here my Xorg.conf .

Thanks a lot again.

Maybe the configuration scripts changed since the time I updated the guide. I will try it myself again and see if I can reproduce the problem you had.


Anyway, glad the guide was helpful to you

[nankura]

is this guide still valid?

someone in this post said in 10.10 all you have to do is install
libgl1-mesa-dri-experimental

and disable your main driver in jockey

or do i still have to follow the guide?

Also im wondering if this kills the screen tearing problem, the latest nvidia drivers ( appearently since the 200 series drivers ) have had trouble communicate with VSync and compositing window managers

And i have yet to find a permanent fix,

But im wondering if using the Nouveau 3D Driver will fix this little issue and finally let me use compositing

Drivers in ubuntu repository are outdated. The guide is for those who need the latest version.

Don't know.

I've been fighting a losing battle to try and get 3D with an old GeForce 6800...worked fine up to 9.10, won't hardly do 2D with anything past that.

The proprietary drivers have been nothing but problems...is there 3D support for a card this old with nouveau? And if so, will the posted instructions work to install it?

Nouveau supports pretty well 6800, but don't expect good performance. Also, if you don't need the latest 3d drivers, you could just libgl1-mesa-dri-experimental package from ubuntu repository which provides pretty old 3d nouveau driver.

Well, I don't plan on playing any graphics-intense games or anything with it...just making sure my wife's Facebook games don't look like stop-motion.

How does one install the experimental package?

Use synaptic package manager or run the following command:

sudo apt-get install libgl1-mesa-dri-experimental

Also you'll need to install xserver-xorg-video-nouveau for 2D and uninstall official nvidia driver to avoid conflicts.
