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 :

3XXX (on AT91RM9200-EK)
break;
default:
vyres = var.yres_virtual;

and now it is working well ! :) But I do not know if this patch can affect
other framebuffers... If it does not, is it possible to include it in CVS?
Regards,
Guillaume GARDET
