The RootFS Auto-resize feature has changed!!! 
Once everything is done after auto-resizing, the power will turn off automatically. 
Please Wait a couple of minutes and plug/unplug the power cable when the blue LED is off.

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)

CPU governor: If you want to change the CPU governor, install cpufrequtils and try the following commands. Don't forget to disable ondemand service.

target

$ sudo apt install cpufrequtils
# You can specify the governor as you want such as ondemand, performance, powersave, interactive, and so on.
$ echo 'GOVERNOR="{GOVERNOR}"' | sudo tee /etc/default/cpufrequtils; sudo update-rc.d ondemand disable; systemctl mask ondemand
$ reboot

e.g. Check the CPU governor if you feel the system slowness. If it is not “performance”, try..

target

$ cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor
$ echo 'GOVERNOR="performance"' | sudo tee /etc/default/cpufrequtils; sudo update-rc.d ondemand disable; systemctl mask ondemand;
$ reboot

Chromium browser 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. This process must not be interrupted.
To enable Auto-login, edit /usr/share/lightdm/lightdm.conf.d/60-lightdm-gtk-greeter.conf file like this.

[Seat:*]
greeter-session=lightdm-gtk-greeter
autologin-user=odroid
