Things to do after installing Ubuntu 18.04

Today i installed Ubuntu 18.04. Ubuntu 18.04 use GNOME desktop instead of Unity Desktop. I like some of the new features, but missed some feeatured i am used to in Ubuntu 16.04. First thing i notice was i can’t easy change sound output device like in Ubuntu 16.04, i expected Ubuntu 18.04 made it easier. But after spending some time, i found out i can customize Gnome to make it work like i need.

Show date in top bar

I want to show date along with time in top bar. To enable this, you need to install gnome-tweek-tool.

Now start gnome tweak tool, this is available as Tweaks

Gnome Tweaks

Go to Tweaks > Top Bar. Under clock, set “Date” to On.

Gnome Tweaks Enable Date

Now you will see full date along with time.

Set time 12 Hour format

By default Ubuntu 18.04 show time in 24 hour format. I prefer 12 hour format with AM/PM.

Click on Power button, select Settings.

Go to Details > Date & Time
