Probably because linux retrieved the values from the monitor. Why didn't Xorg on FreeBSD? Maybe there is a faulty connection in the monitor lead; maybe a lot of things. But I suspect example.org is not the way to go. You should be able to see what linux actually found/setup in one of the xorg log files. Try perusing /var/log/Xorg.0.log Malcolm
