hello again,

thanks for your effort Karol. i've just found another time the bug and:

1) kept the vga cable in the same place.

2) connected a dvi cable between the same computer and the same monitor.

3) told xrandr to dup the signal through the dvi cable:

DISPLAY=:0.0 xrandr --output DVI-D-1 --mode "1920x1080" --same-as VGA-1

4) voilà! the monitor, all alone, switched to dvi input and there is my 
x session up and running.

5) if i force the monitor to change to vga input it refuses it and 
returns to dvi

so i think the driver does its job but without actually sending anything 
through the vga cable.


thanks.
