As I understand it, it's not vnc, but more a kind of x-forward..
performance is great, just like been connected to the nvidia card directly
(or close too).. this is not just a POC.. this is actually usable!!..
Regard arch, I don't know.. but isn't it packaged the same way in
ubuntu???

Using vnc seems like it would induce some lag or cpu cycles. Whats the
performance like?
Also on a related note, I use Arch, and since libgl gets packaged with
with
the nvidia proprietary modules now, I'm guessing I would need to find a
way
to install both the open source libgl and the nvidia one? Thanks

*Emne: *[Hybrid-graphics-linux] Optimus Solution found!!!! Using my
Nvidia
card in my Alienware M11X R2!!!
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

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

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..
