hi, all
I am writing a gfxdriver for Fujitsu mb86296 video card under DirectFB.
When I run a example df_fire from DirectFB-examples-1.0.0.tar.gz, there
is no output on the computer screen, it is black completely, and the
error result looks like this:
sh-3.00# ./df_fire

The code you sent is looking fine. Please try a build with debug enabled
