The RootFS Auto-resize feature has changed!!! 
Once everything is done after auto-reboot, the power will turn off automatically. Wait a couple of minutes.
Please press the power button if the blue LED is off.

• Tons of issues undocumented.
• To enable Auto-login, edit /usr/share/lightdm/lightdm.conf.d/60-lightdm-gtk-greeter.conf file like this.

• [SeatDefaults]
  greeter-session=lightdm-gtk-greeter
  autologin-user=odroid

• Kodi and Gsteamer playback is sluggish when we play 1080p video clips. Slow GLsink rendering seems to be a root cause even MFC HW decoder works fine.
• Some UASP capable USB-to-SATA bridge controllers are not compatible. If your external HDD is not working properly, add its VID/PID in boot.ini Boot arguments to disable the UAS function something like this.

• usb-storage.quirks=0x0bc2:0x2322:u

• Youtube video on Chromium Browser is not smooth. But the video quality can be improved a lot with “h264ify” extension in Chrome Web Store.
• Pre-installed FireFox ver 55 is crashing. Install a previous version manually until Canonical fix it.
