Linux++:::: Dual heads with Fedora 10
Posted at 19.Dec,2008 14:57  Comments 0 / Trackbacks 0 / Like this post!

I have a rather nerve wrecking experience with Fedora 10.

My upgrade try from F9 halted midway because of faulty DVD. Always check the media when prompted!

The next try thru URL, anaconda died. No other way but fresh install. That went great.

Now, the user experience. I use KDE as my wm and mostly use keyboard shortcuts to move around. I seldom touch my mouse.

Initially, alt-fn, alt-arrow keys will switch to the virtual tty. A yum update helps solve that (but I needed to download more that 200 packages).

Now two things bother me:

  • setting up dual heads
  • connecting to the corporate wpa2

I've solved the first one by making use of xrandr

running xrandr returns the output we have:

 Screen 0: minimum 320 x 200, current 3080 x 1050, maximum 3360 x 1050
 VGA-0 connected 1400x1050+0+0 (normal left inverted right x axis y axis) 408mm x 306mm
   1400x1050      74.8*    60.0
   1280x1024      85.0     75.0     60.0
   1280x960       85.0     60.0
   1152x864       75.0
   1024x768       85.0     75.1     75.0     70.1     60.0
   832x624        74.6
   800x600        85.1     72.2     75.0     60.3     56.2
   640x480        85.0     75.0     72.8     75.0     60.0     59.9
   720x400        85.0     70.1
   640x400        85.1
   640x350        85.1
   0x0             0.0
 DVI-0 disconnected (normal left inverted right x axis y axis)
 LVDS connected 1680x1050+1400+0 (normal left inverted right x axis y axis) 0mm x 0mm
                  60.1*+
   1280x1024      60.0
   1280x960       60.0
   1024x768       60.0
   800x600        60.3
   640x480        59.9

To set ddual heads we have to put these in xorg.conf:

 Section "Device"
        Identifier  "Videocard0"
        Driver      "radeon"
       Option      "VBERestore" "true"
 EndSection

 Section "Screen"
        Identifier "Screen0"
        Device     "Videocard0"
        DefaultDepth     24
        SubSection "Display"
                Viewport   0 0
                Virtual   3360 1050
                Depth     24
                Modes    "1680x1050"
        EndSubSection
 EndSection

The most important item is the Virtual size. Otherwise we can't run the last command:

 [~]$ xrandr --output VGA-0 --left-of LVDS --fb 3360x1050

This will put my VGA-0 to the left of my notebook screen.

The only thing now is to make this permanent.

Other things we can do with xrandr:

  xrandr --auto #
  xrandr -h #:)

Hope this help others. This site has more.

Now, if anybody knows how to connect to wpa/gtc ?
