I'm trying to get a PCIe and a PCI video card to work together for a multi-monitor setup but I'm getting "(EE) No devices detected. Fatal server error: no screens found". This is under Ubunutu 9.04 and both are nvidia cards. According to the log, both cards are being detected and the nvidia driver is being loaded. I'll really appreciate the time anyone could spend helping me look at this.
