Greetings everyone. I'm really happy to have found DirectFB, I'm hoping it will help me to achieve my goals of creating some intelligent digital signs.
I'm using a Pandaboard ES, which is running Ubunto 12.04.1 LTS with the TI supplied OMAP drivers. I am not running X11 on this system and Wayland isn't yet supported, but our old friend /dev/fb0 works fine :-) I pulled a copy of DirectFB from git, built it natively using --with-gfxdrivers=omap and it built and installed (woot!) and I can run most of the demos (there are a few things that break from missing data files but that is ok) I would love it if I could get 2D acceleration, not sure if that is from the omap driver or the pvr2d driver (which I did not build, but I could try I suppose). My first question is this one, when I run any dfb program (and dfbinfo as well) I get this error: (*) FBDev/Mode: Setting 1920x1080 RGB32 (*) FBDev/Mode: Switched to 1920x1080 (virtual 1920x1080) at 32 bit (RGB32), pitch 8192 (!) DirectFB/FBDev: Could not set gamma ramp --> Invalid argument (*) FBDev/Mode: Setting 1920x1080 RGB32 (*) FBDev/Mode: Switched to 1920x1080 (virtual 1920x1080) at 32 bit (RGB32), pitch 8192 (!) DirectFB/FBDev: Could not set gamma ramp --> Invalid argument This comes from the code in systems/fbdev.c where it has this : D_INFO( "FBDev/Mode: Switched to %dx%d (virtual %dx%d) at %d bit (%s), pitch %d\n", var.xres, var.yres, var.xres_virtual, var.yres_virtual, var.bits_per_pixel, dfb_pixelformat_name(config->format), shared->fix.line_length ); if (config->format == DSPF_RGB332) dfb_fbdev_set_rgb332_palette(); else dfb_fbdev_set_gamma_ramp( config->format ); This seems like it is trying to set a gamma ramp because the config->format value isn't recognized as a truecolor format? --Chuck
