I'm using Ubuntu 9.10 on AMD64 with Nvidia driver and GeForce 7600 card. 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. I'm having a problem configuring this properly. I want two separate X screens. I can only get it to work with both at 1680x1050. In fact, if I change the HDTV setting to be 1920x1080, it reverts to 1680x1050. If I disable the second monitor and use only the HDTV and tell it to use 1920x1080, if I get it to do that (or get both X/Nvidia and the HDTV to say that's what they are doing), a lot of the desktop is off the edges of the screen and not visible. There is something called Xinerama. If I enable Xinerama, nothing works (I think I was getting no X) and it tells me that RANDR is not available. I would greatly appreciate any tips you can share. Thanks. Mike
