[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.

- 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.
