I have Ubuntu 16.04 on my Aspire ES1-512 but when I want to restart or power off my computer does not turn off completely, only the loading points appear under "Ubuntu" but the screen freezes, so I must use the button off, this happened to me with Fedora, Debian and Kali. Is there a way to fix it?
In that case, you have the following test to see what happens. 1: Open a terminal and type the following command (it will only work for you based on debian)
sudo shutdown -h now
check if the equipment is turned off, if so, I recommend that you then create a script in bash with the command I gave you and when you want to turn off the equipment you run.
To shut down Ubuntu, you could try:
sudo shutdown -h now
or
sudo poweroff
In case you would like to restart:
sudo shutdown -r now
or
sudo reboot
