I did, but it still drove the external monitor with 1024x768 which really sucked, I even got horizontal panning. > Most likely a configuration issue then. Yes, and I found it now! After looking at my log file again I noticed it was complaining about hsync being out of range for the 1280x1024 mode. I'd never seen that before so I assume it only came when I added the virtual screen size. Anyway, the fix was to increase the CRT2HSync option. I have no idea what values are good though... This is what I have now, and it seems to work: Option "CRT2Position" "LeftOf" Option "CRT2HSync" "10-160" Option "CRT2VRefresh" "50-75" Now the only remaining problem is that I get some drawing artifacts if I quickly pan downwards on the powerbook's screen by pulling the mouse down... But that's ok, not a very frequent operation :) Thanks for the help and encouragement, johannes
