Userspace Update

  • 64-Bit Chromium with EGL Enabled
  • Kodi 16.1 (Auto-framerate-switching [Adjust display refresh rate] works if HPD option is changed)
  • CEC Support
  • apt-fast installed
  • Ubuntu updated to 16.04 final release

Known issues

  • 64bit Firefox is very unstable (you need to try 32bit Firefox)
  • Some 4K video files rendering on Kodi is not smooth on 4K/UHD monitor
  • KODI audio Passthrough and Dynamic refresh rate are not implemented yet
  • mySQL/KVM needs an editing of boot.ini file to change the system timer source to ARMv8 Architecture from the Meson. But the ARMv8 timer affects the VPU/GPU system accuracy.
  • 32bit x11 Mali driver is not available. We need much longer time to investigate the complicated dependencies.
  • NTP time syncing takes long time (sometimes around 1~2 minutes)
  • Mouse cursor keeps blinking on Chromium due to GPU acceleration
  • Tons of issues not listed. :-x

How to update the kernel and system

  • sudo apt-get update && sudo apt-get upgrade && sudo apt-get dist-upgrade 

Black screen after running "sudo apt-get autoremove"

  • If you do “sudo apt-get autoremove” , the essential video drivers can be removed accidentally.
    In that case, run “sudo apt install xserver-xorg-video-mali mali-x11 kodi aml-libs” to recover it.
