DirectFB (short for English Direct Frame Buffer ) is a graphics library that provides a hardware accelerated video output available as well as input devices such as keyboard and mouse managed. An interface for sound output is also offered. DirectFB is used in many Unix-like operating systems at the console level to display information and graphics. On larger operating systems it can operate the screen display alternately with the X.Org server . In addition, DirectFB can output the graphic via X or SDL, so that DirectFB programs are displayed in a window in a running X server. With the application XDirectFB written for DirectFB it is also possible to use many applications written for X under DirectFB.
Toolkit support
The GUI toolkits GTK + and Qt , which are widely used in the Unix environment, and the less common FLTK have been ported to DirectFB. Software that only uses one of these three libraries to draw the user interface can therefore be used under DirectFB without adapting the source code . For this, the program only has to be compiled against the DirectFB version of the corresponding toolkit .
more details
In the embedded sector, DirectFB is seen as a resource-saving replacement for the X.Org server , so that in most cases there is no need for an X server at all.
The Linux distribution SPBLinux uses DirectFB to display the graphical user interface on the screen.
Furthermore, with DirectFBGL it is possible to use OpenGL for outputting hardware-accelerated 3D graphics under DirectFB.
