Re: change color depth to 16bit

Well, on the thread "Re: xorg configuration" i got the hint to change to 16bit color depth without using xorg.conf.

Now, i cannot reach the virtual resolution to put each screen on each monitor, that is
1440x900 and 1920x1080 . All I get is 1920x1920, the external monitor is not on the right of
the laptop monitor, there is one over the other.
I have both screen on both monitors, which is quite problematic.

Is there any way to tell X to use a virtual resolution of 3360x1080 (1920+1440 x 1080) without using xorg.conf ?
I run Xorg -configure and i have a large and messy xorg.conf which i'mtrying to avoid .

I run :
xrandr --newmode "1440x900_60.00"  106.50  1440 1528 1672 1904  900 903 909 934 -hsync +vsync
xrandr --addmode  LVDS 1440x900_60.00

xrandr --newmode "1920x1080_60.00"  173.00  1920 2048 2248 2576  1080 1083 1088 1120 -hsync +vsync
xrandr --addmode VGA-0 1920x1080_60.00

xrandr --output VGA-0 --mode 1920x1080_60.00
xrandr --output VGA-0 --right-of LVDS

last command gives :
xrandr: screen cannot be larger than 1920x1920 (desired size 3360x1080)
