Daplas" I have a TFT LCD screen (1600x1200) with both D-Sub and DVI inputs, and a NV25 [GeForce4 Ti 4600] with same outputs. Using the old D-Sub cable works fine: rivafb: nVidia device/chipset 10DE0250 rivafb: nVidia Corporation NV25 [GeForce4 Ti 4600] rivafb: Detected CRTC controller 0 being used rivafb: RIVA MTRR set to ON rivafb: Found EDID Block from BUS 2 rivafb: setting virtual Y resolution to 83886 Console: switching to colour frame buffer device 200x75 rivafb: PCI nVidia NV25 framebuffer ver 0.9.5b (128MB @ 0xE0000000) but with the DVI cable (dsub disconnected) I get a blank screen as soon as rivafb takes over: rivafb: nVidia device/chipset 10DE0250 rivafb: nVidia Corporation NV25 [GeForce4 Ti 4600] rivafb: Detected CRTC controller 0 being used rivafb: RIVA MTRR set to ON rivafb: Found EDID Block from BUS 3 EDID checksum failed, aborting rivafb: setting virtual Y resolution to 209715 Console: switching to colour frame buffer device 80x30 rivafb: PCI nVidia NV25 framebuffer ver 0.9.5b (128MB @ 0xE0000000) I then have to plug the d-sub back in to see the output. [side note: 2.6.8.1 shows only garbage on reconnecting dsub, so rc2 is an improvement.] No I don't understand the lingo here, but I assume EDID/BUS2/BUS3 and the checksum failure are the bits I'm interested in here. I'm willing to do the grunt work to get this fixed, but can you guys give me a heads up on how this stuff works, and what might be involved in a fix?
