Technorati tag(s):

Setting up dual heads for Fedora 9 is way different compared to older fedoras.

I have an old HP nx 8220 that have been running fedoras since forever. I usually upgraded to even numbered fedoras, but I cannot resist fedora 9.

To setup dual heads, do the following:

  • run xrandr:
      Screen 0: minimum 320 x 200, current 1680 x 1050, maximum 3360 x 1050
     VGA-0 disconnected (normal left inverted right x axis y axis)
     DVI-0 disconnected (normal left inverted right x axis y axis)
     LVDS connected 1680x1050+0+0 (normal left inverted right x axis y  axis) 0mm x 0mm
       1680x1050      60.1*+
       1360x768       59.8     60.0
       1152x864       60.0
       1024x768       60.0
       800x600        60.3
       640x480        59.9
     S-video disconnected (normal left inverted right x axis y axis)
    

Here I have my notebooks screen (LVDS) and VGA Setting up dual heads for Fedora 9 is way different compared to older fedoras.

I have an old HP nx 8220 that have been running fedoras since forever. I usually upgraded to even numbered fedoras, but I cannot resist fedora 9.

To setup dual heads, do the following:

  • run xrandr:: $ xrandr Screen 0: minimum 320 x 200, current 3360 x 1050, maximum 3360 x 1050 VGA-0 connected 1680x1050+1680+0 (normal left inverted right x axis y axis) 408mm x 306mm 1680x1050 74.9+ 69.9 60.0 59.9 1600x1024 60.2 1400x1050 85.0 74.8 70.0 60.0 1280x1024 85.0 85.0 75.0 60.0 60.0 1440x900 59.9 1280x960 85.0 60.0 60.0 1360x768 59.8 60.0 1152x864 85.1 85.0 75.0 75.0 70.0 60.0 1024x768 85.0 85.0 75.1 75.0 70.1 60.0 832x624 74.6 800x600 85.0 85.1 72.2 75.0 60.3 56.2 640x480 85.0 85.0 75.0 72.8 75.0 60.0 59.9 720x400 85.0 70.1 640x400 85.1 640x350 85.1 DVI-0 disconnected (normal left inverted right x axis y axis) LVDS connected 1680x1050+0+0 (normal left inverted right x axis y axis) 0mm x 0mm 1680x1050 60.1+ 1360x768 59.8 60.0 1152x864 60.0 1024x768 60.0 800x600 60.3 640x480 59.9 S-video disconnected (normal left inverted right x axis y axis)

Here I have my notebooks screen (LVDS) and VGA-0, and VGA-0 is to the right of LVDS.

Add these lines to Device section::

Section "Device" Identifier "Videocard0" Driver "radeon" Option "monitor-LVDS" "lvds" #<-- Option "monitor-VGA-0" "vga0"#<-- Option "VBERestore" "true"

EndSection

Add these sections to xorg.conf:

  Section "Monitor"
        Identifier "lvds"
        Option "Position" "0 3360" #the notebook's monitor is the default, starts from 0
 EndSection

 Section "Monitor"
        Identifier "vga0"
        Option "RightOf" "lvds"
 EndSection

And add the modes and virtual size to Screen section:

 Section "Screen"
        Identifier "Screen0"
        Device     "Videocard0"
        DefaultDepth     24
        SubSection "Display"
                Viewport   0 0
                Depth     24
                Modes   "1680x1050" #screen res
                Virtual 3360 1050 #screen res for dual heads

        EndSubSection
 EndSection

This should have been easier, but there's no GUI afaik. system-config-display do't work.
