Hi..
As I also have written in the howto here:
http://www.martin-juhl.dk/2011/05/optimus-on-linux-problem-solved/
You currently lose 3D acceleration on the intel card, caused to the
mesa libraries for nvidia is installed and overwrites the intel ones..
so right now you need to either run gnome through the nvidia as well..
or forget about transparency on the desktop for now...
I will look into this, I don't think it will be hard to fix...

Uhm
This is weird. I lost desktop effects with the intel card.
Icons on the systray lost transparency also. Seems like there is a
problem with the GL extensions or something.

Hi..
I haven't found the MUX.. as far as I can tell the M11X doesn't
have a mux.. this solution actually works the way optimus is meant
to work.. by using the intel card to disable everything, and only
offload though stuff to the Nvidia card...
I discovered that the never versions of the nvidia driver allowed
me to create a virtual screen on the nvidia card.. and worked my
way from there...

Using my Nvidia card in my Alienware M11X R2!!!
Can you tell me how you identified the card MUX. I am a little
confused or point to a link. I have a Asus NV61J with the 325M
optimus Nvidia card. But when I looked into the specs of your
machine you also have an Optimus "enabled". As a side note I love
using linux and was wondering if there is anything I should read
to be more proficient like you are with this kind of stuff.

Hi all..
I have found a way to use the nvidia card in machines WITHOUT
the optimus mux...
There are still a few flaws... but in my regard they are few...
First of all I have this running on my Alienware M11X R2, on
Ubuntu Natty 11.04 64-bit.. And haven't tried it on any other
configurations.. so I hope you can report back, if it works on
other laptops (it should) and other distributions....
Here it goes:
First of all download the following:
General:
http://www.martin-juhl.dk/optimus/xorg.conf
32-bit deb-based:
http://www.martin-juhl.dk/optimus/turbojpeg_1.11.1_i386.deb
http://www.martin-juhl.dk/optimus/VirtualGL_2.2.1_i386.deb
64-bit deb-based:
http://www.martin-juhl.dk/optimus/turbojpeg_1.11.1_amd64.deb
http://www.martin-juhl.dk/optimus/VirtualGL_2.2.1_amd64.deb
32-bit rpm-based:
http://www.martin-juhl.dk/optimus/turbojpeg-1.11.i386.rpm
http://www.martin-juhl.dk/optimus/VirtualGL-2.2.1.i386.rpm
64-bit rpm-based:
http://www.martin-juhl.dk/optimus/turbojpeg-1.11.x86_64.rpm
http://www.martin-juhl.dk/optimus/VirtualGL-2.2.1.x86_64.rpm
Source:
http://www.martin-juhl.dk/optimus/turbojpeg-ipp-1.11.1.tar.gz
http://www.martin-juhl.dk/optimus/VirtualGL-2.2.1.tar.gz
Files can also be found here:
http://sourceforge.net/projects/virtualgl/files/
Ok... Installation:
Start by installing the nvidia driver:
sudo aptitude install nvidia-current (ubuntu)
then put the xorg.conf in /etc/X11/
after that, install the two files you downloaded above:
sudo dpkg -i turbojpeg* VirtualGL* (deb)
or
sudo rpm -ihv turbojpeg* VirtualGL* (rpm)
Now run:
sudo vglserver_config
answer as below:
1) Configure server for use with VirtualGL in GLX mode
2) Unconfigure server for use with VirtualGL in GLX mode
X) Exit
Choose:
1
Restrict 3D X server access to vglusers group (recommended)?
[Y/n]
n
Restrict framebuffer device access to vglusers group
(recommended)?
[Y/n]
n
Disable XTEST extension (recommended)?
[Y/n]
y
... Creating /etc/modprobe.d/virtualgl.conf to set requested
permissions for
/dev/nvidia* ...
... Attempting to remove nvidia module from memory so device
permissions
will be reloaded ...
ERROR: Module nvidia is in use
... Granting write permission to /dev/nvidia0 /dev/nvidiactl

... Modifying /etc/X11/xorg.conf to enable DRI permissions for

... Adding xhost +LOCAL: to /etc/kde4/kdm/Xsetup script ...
... Disabling XTEST extension in /etc/kde4/kdm/kdmrc ...
Done. You must restart the display manager for the changes to
take effect.
IMPORTANT NOTE: Your system uses modprobe.d to set device
permissions. You
must execute rmmod nvidia with the display manager stopped in
order for the
new device permission settings to become effective.
1) Configure server for use with VirtualGL in GLX mode
2) Unconfigure server for use with VirtualGL in GLX mode
X) Exit
Choose:
x
Then:
append the following two lines to /etc/profile
VGL_DISPLAY=:0.1
export VGL_DISPLAY
and reboot...
Hopefully your computer comes back up..
now you should be able to start applications with:
vglrun <application>
and the nvidia card will be used for acceleration..
btw. <application> needs to contain the full path to the
application if not in the path...
It is still the Intel card running the rest.. and for now I
haven't found a way to activate acceleration for both cards..
so no fancy compiz effects.. but thats no problem for me, as
long as I can use my nvidia card for gaming :D...
Hope this will help someone..
