I had the same issue


You must match the PCI buses to the xorg.conf ones

run lspci | grep VGA

$ lspci | grep VGA

00:02.0 VGA compatible controller: Intel Corporation Core ProcessorIntegrated Graphics Controller (rev 18)

02:00.0 VGA compatible controller: nVidia Corporation Device 0df1 (rev a1)

and modify the xorg file with those numbers

~$ fgrep "PCI" /etc/X11/xorg.conf
    BusID          "PCI:2:0:0"
    BusID          "PCI:0:2:0"

Hi there,

after all, this is great news! Thank you for this solution.

I am running Kubuntu natty 11.04 64bit.
The installation was absolutely smooth and worked as in described in the
HOWTO.
Still, for some reason, the display export does not work here. I appended the
two lines to my /etc/profile and rebooted. System comes up with gui (kde). But
running applications with e.g.
vglrun ./pslaunch

reports: [VGL] ERROR: Could not open display :0.1.

What have I missed?

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...

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