Hi All, I had TwinView working last night, finished up what I was doing and shut the computer down. Today when I turned it back on TwinView is only partially working. The computer boots and runs fine. When X starts you get a desktop on the monitor, and a second desktop on the TV, which is the same as last night. However when I try to run something on the second display (mplayer usually) I get the error "Error: Can't open display: localhost:0.1" Does anyone have any ideas? How do I change permissions for a display? There is a desktop with wallpaper and icons so I know it's almost working :( Also any ideas how turning off the computer may have changed things? Thanks for any help/advice I'm at a loss here.... Chris
