weird graphics issue-need help please

[sairus002]

Im using a laptop with 2 nvidia go 7900GS cards. Everything functions normally but only if I can get the xscreen to display. Every time I boot sabayon the screen will be completely black. I have to switch to a terminal and type, /etc/init.d/xdm restart (I dont know what that does, but i saw on google that it worked for someone who couldnt get the desktop to display.) once I type that in, all the terminals will go black and flicker, and im forced to do a hard shutdown. once i power it up it boots fine and everything works. I have to repeat that process every time i want to use sabayon. I tried typing startx in the terminal and it said that its already active for monitor 0 or something. when I got to the desktop I looked in the nvidia settings and it said GPU 0 was connected to an unknown CRT monitor. I think its trying to display the xscreen on a non-existant monitor.... GPU 1 is the one thats connected to a display. Is there any way I can fix this? can I somehow enable SLI for the 1 (real) display?

I wonder if something is not properly configured in xorg.conf
If noone has a solution, you may want to take a look into http://http.download.nvidia.com/XFree86/Linux-x86_64/180.51/README/appendix-b.html and play a bit with options.

If you find a solution by changing options, please report back, I'm sure devs will find it useful and will try to make next sabayon release work better.

ive been messing with those options for hours with no luck. its the same issue no matter what I do. I tried enabling SLI with several configurations but all that does is disable the real monitor and it displays on the false one.
