It works!

I'm using a Dell XPS 15, with an nvidia GT520M (I think), i5 pre sandy
bridge (i think :P)
Glxgears doesn't run on intel, i think it ran before, i don't know. But
with vglrun it works at 720 FPS
Just an adjustement. I had to change xorg.conf to match the PCI ID from
lspci
luis@luis-XPS-L501X:~$ cat /etc/X11/xorg.conf | grep PCI
BusID "PCI:2:0:0"
BusID "PCI:0:2:0"
luis@luis-XPS-L501X:~$ lspci | grep VGA
00:02.0 VGA compatible controller: Intel Corporation Core Processor
Integrated Graphics Controller (rev 18)
02:00.0 VGA compatible controller: nVidia Corporation Device 0df1 (rev a1)
luis@luis-XPS-L501X:~$
Also, another tip. In KDE you can set a file association for the
executable files and desktop files to open them in vglrun.
Is there a way to find if it's working as expected?

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

... Attempting to remove nvidia module from memory so device
permissions

ERROR: Module nvidia is in use
... Granting write permission to /dev/nvidia0 /dev/nvidiactl for

... 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..
