Hi all, I'm Poletti Francesco from Arenagiochi, a small italian factory working in the field of game amusement machine. We are using the JADE evaluation board from mycable, that has a porting of the directfb library (version 1.2).
We are having problems with the usage of the dual display, particoularly
if I execute the command:
>df_andi --dfb:mode=800x600 --dfb:fbdev=/dev/fb0
it works fine on the first display, on the other hand when I run:
>df_andi --dfb:mode=800x600 --dfb:fbdev=/dev/fb1
It works on the second display!But when I try to have directfb running on
the two display at the same time:
if I run:
>df_andi --dfb:mode=800x600 --dfb:fbdev=/dev/fb0 &
>df_andi --dfb:mode=800x600 --dfb:fbdev=/dev/fb1 --dfb:no-vt
--dfb:no-cursor
I get the error reported at the end of this email, while if I in an
application I try to get information about the second screen (id= 1) I
get:
(#) DirectFBError [IDirectFB::GetScreen]: Requested ID not found!
On my opinion there's something wrong in the frame buffer driver because
if I run "dfbinfo" I get:
>Screen (00) FBDev Primary Screen (primary screen)
>Caps: VSYNC POWER_MANAGEMENT
>Layer (00) FBDev Primary Layer
>Type: GRAPHICS
>Caps: SURFACE BRIGHTNESS CONTRAST SATURATION
Where is the second screen? Do we have to configure something in the
.direfbrc file?
Can someone help us? Do someone have a C/C++ application working using
directfb on the two display at the same time?
Many thanks in advance Francesco.
