   58: # Getting U-Boot
   59: 
   60: Jetson TK1 boards come with Linux4Tegra R19.x installed, which doesn't use U-Boot. The easiest way to get U-Boot is to upgrade to Linux4Tegra R21.x (Linux PC or VM required) following the [quick start guide](http://developer.download.nvidia.com/embedded/L4T/r21_Release_v4.0/l4t_quick_start_guide.txt).

   62: # Modesetting
   63: 
   64: To be able to use the mode setting features of the Tegra DRM driver, you must use the xf86-video-modesetting driver. Put this in xorg.conf:
   65: 
   66: [[!template  id=programlisting text="""
   67: Section "Device"
   68:     Identifier "DRM Modesetting"
   69:     Driver "modesetting"
