After a lot of tests I figured out that I have to add a line

	Virtual   2048 2048

into the xorg.conf, SubSection "Display", to get the hight resolution of
the VGA of the TV; xrandr -q says now:

$ xrandr -q
Screen 0: minimum 320 x 200, current 1024 x 600, maximum 2048 x 2048
VGA connected (normal left inverted right x axis y axis)
   1920x1080      60.0 +
   1280x1024      60.0  
   1360x768       60.0  
   1152x864       60.0  
   1024x768       60.0  
   800x600        60.3  
   640x480        59.9  
   720x400        70.1  
LVDS connected 1024x600+0+0 (normal left inverted right x axis y axis) 222mm x 125mm
   1024x600       60.0*+
   800x600        85.1     72.2     75.0     60.3     56.2  
   640x480        85.0     72.8     75.0     59.9  
   720x400        85.0  
   640x400        85.1  
   640x350        85.1  


and I can switch-on the VGA with something like

$ xrandr --output VGA --mode 1920x1080

but, this a) shows on VGA the same content as the screen LVDS (i.e. the laptop
display) and b) affects as well the resolution of the LVDS;

what I want is some so called Xinerama of the two screens: the laptop
stays as it is and the VGA is somehow at its side, both are part of a
bigger virtual ascreen and one can move the mouse and X11 clients from
one screen to the other, as shown in this page:

Will continue working on this;
