I'm really desperate here, and would appreciate your help.
I have an Alienware M17X laptop with dual Nvidia GTX280M video cards,
Ubuntu 9.10 64-bit kernel - 2.6.31-16-generic.
The installation was smooth excluding the video cards.
I tried installing the drivers through the Hardware Drivers (the easy way)
added this: http://ppa.launchpad.net/nvidia-vdpau/ppa/ubuntu
to the list of repositories and got the following drivers available: 173,180,185,190,195(recommended).
So I tried them all (did 4 re-installs already) with a very poor result - the cards are detected and the drivers were installed ok, but the performance is really a no-go.
I'm not even talking about the SLI yet. Just trying to make one card work as it should.
What I get is 136FPS in phoronix lightsmark test
at 19020x1200 rez. The card should perform 4x from what it does (I know it because the phoronix team did it with a Clevo laptop with single GTX280M card and the older 185.x driver).
Also I noticed that the Nvidia X-server shows my cards as PCI 8X
instead of 16X
I think it's a driver issue. So right now I'm trying to install the same driver phoronix used and have some trouble: in the process the installer says it needs to compile the Nvidia driver kernel and is unable to do so, so it fails.
What am I missing here? Do I need some prerequisites to be installed prior doing it?
Please, help a newbie, as it's the only thing still keeping me from deleting my windoze partition...
P.S> Part of lspci output:
02:00.0 VGA compatible controller: nVidia Corporation GT200 [GeForce GTX 280M] (rev a2)
03:00.0 VGA compatible controller: nVidia Corporation GT200 [GeForce GTX 280M] (rev a2)
As you can see the cards are detected.
