I have just upgraded from 16.04 to 18.04.1 LTS.In 16.04 I could see the battery icon on the screen with time till flat and percentage charge showing as hours/minutes and a percentage in the top bar. This doesn't seem to be available as an easily configurable permanent display option in 18.04.
Can anyone please tell me how I can make it display this?
gnome-tweak-tool and make the appropriate changes in the
Top Bar tab as seen below:
sudo apt install gnome-tweak-tool
