My system have two monitors connected to my system.
My xorg.conf starts VGA-0 to the left of DVI-A-0.
Both starts at resolution 1280x1024 by default (not changed by me).

VGA-0 is capable of running the resolution 1600x1200, but here comes the
problem:
xake@lillen ~ $ xrandr --output VGA-0 --mode 1600x1200
xake@lillen ~ $ xrandr
Screen 0: minimum 320 x 200, current 2560 x 1200, maximum 3000 x 3000

   320x240       120.1  
DVI-D-0 disconnected (normal left inverted right x axis y axis)

As you can see in this output the "current" for "Screen 0" is less then the
width of VGA-0 and DVI-A-0 making a part of the left screen also appere on the
right.

However if I do:

xake@lillen ~ $ xrandr
Screen 0: minimum 320 x 200, current 2560 x 1200, maximum 3000 x 3000
VGA-0 connected 1600x1200+0+0 (normal left inverted right x axis y axis) 352mm

   800x600        72.2     75.0     60.3     56.2  
   640x480        75.0     72.8     66.7     60.0     59.9  
   720x400        87.8     70.1  
   512x384       120.0  
   400x300       120.6  
   320x240       120.1  
DVI-D-0 disconnected (normal left inverted right x axis y axis)

Then as you can see everything works nice.

So it seems changing the resolution the output of VGA-0 (theleft screen) does
not setup a correct screen size, but with xrandr turn off DVI-A-0 and restore
its setup again both monitors seems to work nice.
