Dual Monitor Support

Some sunxi devices (such as Mele A1000/A2000 or Cubietruck) have both HDMI and VGA connector available. It is possible to connect two different monitors to these connectors simultaneously. As explained in the disp init configuration section of the Fex Guide some tweaks are necessary in the fex file too. An example of a working fex configuration tweak:

[disp_init] disp_mode = 2 screen0_output_type = 4 screen1_output_type = 3 screen0_output_mode = 11 screen0_output_mode = 5

This sets the dual monitor mode and the same 1280x720 screen resolution for both VGA (/dev/fb0) and HDMI (/dev/fb1) monitors.

You can use something like the following /etc/X11/xorg.conf file ("fbturbo" can be also replaced with "fbdev" there): Section "Device" Identifier     "FBDEV 0" Driver         "fbturbo" Option         "fbdev" "/dev/fb0" EndSection

Section "Device" Identifier     "FBDEV 1" Driver         "fbturbo" Option         "fbdev" "/dev/fb1" EndSection

Section "Screen" Identifier     "VGA" Device         "FBDEV 0" Monitor        "Monitor name 0" EndSection

Section "Screen" Identifier     "HDMI" Device         "FBDEV 1" Monitor        "Monitor name 1" EndSection

Section "ServerLayout" Identifier     "Default Layout" Screen         0 "VGA" Screen         1 "HDMI" RightOf "VGA" EndSection
