DirectFB ======== Supports: - Hardware YUV overlays - OpenGL - software only - 2D/3D accelerations (depends on directfb driver) - multiple displays - windows What you need: * DirectFB 1.0.1, 1.2.x, 1.3.0 * Kernel-Framebuffer support: required: vesafb, radeonfb .... * Mesa 7.0.x - optional for OpenGL /etc/directfbrc This file should contain the following lines to make your joystick work and avoid crashes: ------------------------ disable-module=joystick disable-module=cle266 disable-module=cyber5k no-linux-input-grab ------------------------ To disable to use x11 backend when DISPLAY variable is found use export SDL_DIRECTFB_X11_CHECK=0 To disable the use of linux input devices, i.e. multimice/multikeyboard support, use export SDL_DIRECTFB_LINUX_INPUT=0 To use hardware accelerated YUV-overlays for YUV-textures, use: export SDL_DIRECTFB_YUV_DIRECT=1 This is disabled by default. It will only support one YUV texture, namely the first. Every other YUV texture will be rendered in software. In addition, you may use (directfb-1.2.x) export SDL_DIRECTFB_YUV_UNDERLAY=1 to make the YUV texture an underlay. This will make the cursor to be shown. Simple Window Manager ===================== The driver has support for a very, very basic window manager you may want to use when running with "wm=default". Use export SDL_DIRECTFB_WM=1 to enable basic window borders. In order to have the window title rendered, you need to have the following font installed: /usr/share/fonts/truetype/freefont/FreeSans.ttf OpenGL Support ============== The following instructions will give you *software* OpenGL. However this works at least on all directfb supported platforms. As of this writing 20100802 you need to pull Mesa from git and do the following: ------------------------ git clone git://anongit.freedesktop.org/git/mesa/mesa cd mesa git checkout 2c9fdaf7292423c157fc79b5ce43f0f199dd753a ------------------------ Edit configs/linux-directfb so that the Directories-section looks like ------------------------ # Directories SRC_DIRS = mesa glu GLU_DIRS = sgi DRIVER_DIRS = directfb PROGRAM_DIRS = ------------------------ make linux-directfb make echo Installing - please enter sudo pw. sudo make install INSTALL_DIR=/usr/local/dfb_GL cd src/mesa/drivers/directfb make sudo make install INSTALL_DIR=/usr/local/dfb_GL ------------------------ To run the SDL - testprograms: export SDL_VIDEODRIVER=directfb export LD_LIBRARY_PATH=/usr/local/dfb_GL/lib export LD_PRELOAD=/usr/local/dfb_GL/libGL.so.7 ./testgl
