Hi folks,

I'm running Ubuntu 6.06 as of a week ago (first foray into linux that's lasted more than 3 days) and it's generally going well. I am unable however to get dual head display working. I have previously set up dual-head successfully with xorg and xinerama by referencing the PCI hook of each head - using AGP cards. It runs dual-head under XP just fine. The strange part is that under linux I'm not seeing a 2nd PCI hook with this card. Is this a quirk of PCI-e? Any ideas?

Ubuntu 6.06
Leadtek 7600GS/256 (PCI-e, dual DVI)
