I have machine with Fedora Linux (Schroedinger's cat) 19 with AMD Radeon HD 6800 graphic card. Now, I have monitor plugged in using DVI port and I have TV connected using HDMI port. When machine is booting, the TV is automatically selected as primary screen, but I would like to have my Monitor (DVI port) selected as primary screen and TV (HMDI port) as secondary screen. How do I tell that to Fedora?
You should be able to use the command
xrandr to configure which device is the primary etc. See this wiki article titled: Xrandr on the Gentoo wiki for several examples.
$ xrandr --output LVDS --mode 1024x768 $ xrandr --output DVI-0 --auto --left-of LVDS $ xrandr --output LVDS --primary
See the man page for
xrandr for more on how to use it.
