I've experimented a bit more with my configuration. As I mentioned earlier, you can assign monitors to outputs in the Device section. What I found was that specifying HorizSync or VertRefresh in the Monitor section caused problems. What works: Section "Monitor" Identifier "Monitor0" VendorName "PNR" ModelName "Planar PE190" Option "Position" "1024 0" EndSection Section "Monitor" Identifier "Monitor1" VendorName "Philips" ModelName "Philips 150B3" Option "Position" "0 0" EndSection Section "Device" Identifier "Card0" Driver "mga" VendorName "Matrox Graphics, Inc." BoardName "MGA G400/G450" BusID "PCI:1:0:0" Option "HWcursor" "off" Option "AGPMode" "4" Option "Monitor-VGA1" "Monitor0" Option "Monitor-VGA2" "Monitor1" EndSection This runs both monitors at their DDC-detected resolution. In my case, that's 1280x1024 for Monitor0 and 1024x768 for Monitor1. If I tried to explicitly set a Mode for Monitor1, it went to 640x480. 'Option "Position" is not used' is still in the log, although it also shows the positions set for both monitors. -Warren Block * Rapid City, South Dakota USA
