Screen 0: minimum 320 x 200, current 1280 x 1024, maximum 2048 x 1200
VGA-1 connected 1280x1024+0+0 (normal left inverted right x axis y axis) 300mm
x 230mm
   1280x1024      60.0* 
   1024x768       85.0     75.0     60.0  
   832x624        74.6  
   800x600        85.1     75.0     60.3  
   640x480        75.0     63.1     59.9  
   720x400        70.1  
VGA-0 disconnected (normal left inverted right x axis y axis)
S-video disconnected (normal left inverted right x axis y axis)

Since VGA-0 is showing as disconnected, that is the one you have to force on:

xrandr --addmode VGA-0 1280x1024
xrandr --output VGA-0 --mode 1280x1024
