Thanks very much pregister.
That bit of info may be quite useful for the up and coming new SLI System.

Thanks for the input mate but unfortunately it did not work here. x crashed in Ultimate Edition and Felicia as soon as I booted with the second card back in.

Hello guys, I too had this frustration for the last 48 hrs. however there is a real solution. and it is as follows. When you boot and it tells you fatal error no screens found that means you are most likely using an SLi setup and the Intrepid OS doesnt know which card to chose so by default, so it chooses none.(stupid i agree) anyway the fix is as follows. You need to figure out which bus the card is on and insert it into the xorg.

basically load up your ubuntu from grub into rescue/recovery mode. then choose the root shell option. Once there type the following command

Code: Select all

sudo lspci | grep VGA

the output should look similar to mine

03:00.0 VGA compatible controller: nVidia Corporation GeForce 8800 GT (rev a2)
04:00.0 VGA compatible controller: nVidia Corporation GeForce 8800 GT (rev a2)

now those numbers in the front are bus ID's so you need to insert them into your xorg.conf under the device section. to do so type ine

Code: Select all

nano /etc/X11/xorg.conf

Section "Device"
Identifier "Configured Video Device"
Busid "PCI:3:0:0"
Driver "nvidia"
EndSection

the part in red is what you need to insert. your numbers will probably be different. (if the first one doesnt work try the 2nd) then just "ctrl+x" to exit and hit "Y" to save.
then type

Code: Select all

sudo reboot

and you are done. worked for me pretty straight fwd.

enjoy!
