SLI & TwinView

CyberZeus1977 · 09-16-09, 08:29 AM

Hi,
my system is equipped with two nVidia Geforce 8600 GTS cards.
I installed Ubuntu 9.04 64-bit. I downloaded and installed nVidia Linux driver version 185.18.36.
After installing the driver, gdm fails to start. So I used

Code:

lspci|grep VGA

to discover my cards. They are in position PCI n° 4 and 5.
I had to edit /etc/X11/xorg.conf in Device section and add

Code:

BusID "PCI:5:0:0"

to tell the driver which card to start from. (I tried "4:0:0" with no success).
I also enabled sli functionality adding

Code:

Option "SLI" "Auto"

in xorg.conf.
Everything works, but not TwinView (I have two monitors, connected and the same card).
The TwinView option in greyed in nvidia-settings applet.
If I comment the Option "SLI" "Auto" lines, TwinView option is selectable.
Have you a suggestion or trick to have both enabled SLI and TwinView?

Thanks

TwinView does not work at the same time as SLI.

Really? In Vista x64 it does...
I have to wait some nVidia Linux driver improvements?

Thanks for your reply!

In 190.xx, when I enable SLI, the driver seems to allow it, but nvidia-settings does not have an option for it.
One screen comes up, however the mouse pointer can travel off screen quite some distance, and windows spawn off screen to where my other monitor should be.
