Hello,
I am attempting to write a FB driver for a small simple embedded linux
system to work with DirectFB. My driver works to the point that I can
echo to /dev/fb0 and I see the first few pixels on the screen change. I
am very new to framebuffers, so I am hoping for a point in the right
direction. When I run dfblayer, this is what I get (this it 0.9.24
btw).
# dfblayer
(*) DirectFB/Config: Parsing config file '/etc/directfbrc'.

FBDev Primary Layer

Height 768
Format RGB16
Buffermode FRONTONLY
(!) DirectFB/FBDev: Could not restore palette!

I have checked state->drawingflags, and that is 0. Also, when I run any
of the example programs, I get "(!?!) *** BUG [dst_pfi:1] ***
[generic.c:6622 in gAcquire()]" repeatedly with nothing on the screen.
I think I have the acceleration flags all set to none.
Can anyone tell what I would need to do to get dfb working?
Thanks,
Matt Spinder
