Components running on DirectFB graphics backend are based on libdirectfb.so library. Compositing windowing system is performed by the default libdirectfb.so window manager module with libdirectfbwm_default.so plugin. Cooperation between various process is achieved through the fusion.ko kernel module.
If the current graphics backend used on HiGFXback is not DirectFB, switch on it with startdfb command. Select one of the following graphics driver interface available on HiGFXback and used by libdirectfb.so library for the display:
- Linux Framebuffer interface (
/dev/fb0) handled with libdirectfb_fbdev.so plugin - KMS/DRM interface (
/dev/dri/card0) handled with libdirectfb_drmkms.so plugin
But depending on the platform, it's possible to use specific graphics driver interfaces based on the libdirectfb.so system module architecture. If available on the platform, hardware accelerated graphic rendering can also be achieved based on the libdirectfb.so gfxdriver module architecture.
When starting on DirectFB graphics backend with startdfb command, select one of the following input driver interface available on HiGFXback and used by libdirectfb.so library for managing the keyboard:
- console interface (
/dev/tty0) handled with libdirectfb_keyboard.so plugin - event device interface (
/dev/input/event0) handled with libdirectfb_linux_input.so plugin
and for managing the mouse:
- PS/2 mouse interface (
/dev/psaux) handled with libdirectfb_ps2mouse.so plugin - event device interface (
/dev/input/event1) handled with libdirectfb_linux_input.so plugin
But depending on the input peripheral, it's possible to use specific input driver interfaces based on the libdirectfb.so inputdriver module architecture.
