Hi Niels
Thanks for your response.
I thought the default was system=fbdev.
Now I have the DFBARGS set to sytem=fbdev with DirectFB-1.3 and when I run
arm-dfbinfo (or any other test DFB application) I see this error.
(!) Fusion/Init: World ABI (44) doesn't match own (45)!
Any idea why? (I am runnning fusion module 8.1.1)
However I tried the DirectFB-1.2 and I brought up two different applications
and it runs just fine. So, I will just
stick to 1.2 version for now and revisit DirectFB 1.3 later.
