When I tried to do something with "Display" in Ubuntu's system panel, it told me that it was unable to make changes and I should try the proprietary controls. So I looked on the same list of apps and found the Nvidia panel. >> I was using two 1680x1050 monitors, but I dropped the first one and >> replaced it with a DVI-to-HDMI cable to my 1920x1080 HDTV.

Nvidia. What I've been doing is telling Nvidia to write to xorg.conf, then I restart and see how it looks. This has almost worked! >> There is something called Xinerama.

Well, do I need to be using Nvidia's proprietary driver? I'd rather use all free software, definitely, but I'll do what I have to do to make the hardware work. If I can use RANDR with a different driver, I guess that's what I'd prefer to do. Mike
