I'm trying to get a reasonable test/dev environment for DirectFB going on
my macbook under parallels (http://www.parallels.com).
I have installed Ubuntu Dapper and built the DFBTutorials etc without
problem;
I have modified my kernel boot parameters to include vga=0x317, which
gives me a 1024x768 16bit frame buffer.
However, when I run the tutorials and examples, I get nothing but a blank
screen, and the following warnings/errors in output:
(!) DirectFB/FBDev: Unsupported pixelformat: rgba 5/11, 6/5, 5/0, 0/16 (16bit)
It's strange to signal 0 bits at 16 :)
(!!!) *** WARNING [unknown format] *** [fbdev.c:1763 in dfb_fbdev_set_mode()]
(!!!) *** ONCE [unsupported destination format] *** [generic.c:7036 in
gAcquire()]
(!) [ 9708: 0.000] --> Caught signal 11 (at 0xe4, invalid address) <--
What am I doing wrong here? I know it wants to work, it's got the heart
of a champion, am I missing something?
Maybe the patch helps.
