Hi List, we have two machines with identical software environments but little difference in the hardware configuration. Hardware configuration differs as following: Machine1 Machine2 Motherboard: SUPER P6SBA MS-6309 ATX VA5 motherboard Display card 1: ATI RADEON (AGP) ATI RADEON (AGP) Display Card 2: ATI Rage XL (PCI) ATI Rage XL (PCI) We connect a projector to the DVI port of ATI RADEON(AGP Card) and monitor (NEC LCD1530V) to ATI Rage XL (PCI) card. Primary card is set to AGP in BIOS. We have the same configuration file, XF86Config-4 on both the machines. This config file only has entries to config the Rage card. We config the AGP Radeon card using the vesafb driver. Our problem : On machine1, when we try to run Xwindows, we get following Error message: (II) Primary Device is: PCI:01:00:00 /* this is right */ (II) ATI: Candidate \\\"Device\\\" section \\\"ATI Rage XL\\\" /* this is fine */ (WW) ATI: PCI/AGP Mach64 in slot 0:15:0 could not be detected (WW) ATI: PCI/AGP Mach64 in slot 1:00:0 could not be detected (EE) No Devices detected whereas on machine2 which has almost same configuration, it works absolutely fine. Please let us know where should we look to solve this problem, what could be the probable solution?
