I'm trying to get DirectFB up and running on a Pandaboard. Good news is
that building 1.7.0 just works, bad news is that its not all there. I
configured --with-gfxdrivers=omap (panda is OMAP4460) and things like
df_knuckle work as does df_particle (I think it doesn't quite look like I
would expect) when ever I run something I get this:
cmcmanis@pandaboard:~/DirectFB-examples-1.6.0/src$ sudo ./df_particle

Not sure what to make of the gamma ramp, this display should be truecolor
(32 bpp) fbset returns this:
cmcmanis@pandaboard:~/DirectFB-examples-1.6.0/src$ fbset
mode "1920x1080"
geometry 1920 1080 1920 1080 32
timings 0 0 0 0 0 0 0
accel true
rgba 8/16,8/8,8/0,8/24
endmode
cmcmanis@pandaboard:~/DirectFB-examples-1.6.0/src$
Which is what I expect. Running Ubuntu 12.04 with the TI drivers loaded.
Thoughts on what I might do next to see about the gamma issue (display is
'dim' which is to say drawing a white line gives me a grey line (about 50%
saturation) which isn't expected.)
