Dear All,
I am new in DirectFB.
I am working on DirectFB-1.4.1.
It is working fine in software mode and when i tried to run it in the
hardware mode i got the segmentation fault. Following are the
debug-trace information,
(*) DirectFB/Core/WM: Default 0.3 (directfb.org)
(!) DirectFB/FBDev: Panning display failed (x=0 y=0 ywrap=0 vbl=1)!
