Known issues and tips

  • 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.
  • NTP time syncing takes long time (sometimes around 1~2 minutes)
  • GPU acceleration should be enabled manually. Add below line into /etc/chromium-browser/default file.
  • CHROMIUM_FLAGS=" --use-gl=egl --ignore-gpu-blacklist --disable-accelerated-2d-canvas --num-raster-threads=2"
  • The root file system will be resized in the first booting process. OS will reboot automatically to complete the resizing process.
  • To enable Auto-login, edit /usr/share/lightdm/lightdm.conf.d/60-lightdm-gtk-greeter.conf file like this.

How to update the kernel and system

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