I modified a bit the patch in order to have the correct size of screen in all
buffermodes

and now it is working well in all buffermodes ! :) But maybe this patch can
affect other framebuffers... (I think it does not) If it does not, is it
possible to include it in CVS?

Objet : [directfb-dev] Patch for fbdev.c for epson S1D13XXX framebuffer
-DirectFB 1.1.1
Hi list,
I am running DirectFB on the board AT91RM9200-EK which uses the epson S1D13XXX
framebuffer (FB_S1D13XXX) and I had a bug with DirectFB.
My screen is 640x480 and the framebuffer mode is : DLBM_BACKVIDEO. So, the
virtual size should be 640x960 and DirectFB reported a size of 640x1024, so I
get a screen size of 640x512 and I lost the bottom of the screen... So, I wrote
a little patch :
