如何直接写入linux framebuffer？

看看FBIOPUT_VSCREENINFO，ioctl和mmap

（我有代码，但没有此电脑，对不起）

编辑：这应该让您开始

  //open file descriptor and get infoinf fdScreen = open( "devicename", O_RDWR );fb_var_screeninfo varInfo;ioctl( fdScreen, FBIOGET_VSCREENINFO, &varInfo );  //set resolution/dpi/color depth/.. in varInfo, then write it backioctl( fdScreen, FBIOPUT_VSCREENINFO, &varInfo );  //get writable screen memory; unsigned short here for 16bit colorunsigned short* display = mmap( 0, nScreenSize,          PROT_READ | PROT_WRITE, MAP_SHARED, fdScreen, 0 );
