Brief: If you are feeling nostalgic, you can easily install Unity in Ubuntu 17.10. Here’s how to do it.
The most talked about feature of Ubuntu 17.10 is the switch to GNOME. Ubuntu has done quite a good job in making Unity users feel at home with the customized GNOME desktop.
But it is not necessary that you will like GNOME. Unity has been part of Ubuntu for last 6 years and over the time, it did gain its fair share of fan following.
If you are among the ones who have upgraded to Ubuntu 17.10 but want to use Unity instead of GNOME, you can easily do that.
However, I must warn you that I am not sure of the kind of support it has got in Ubuntu 17.10. If you face weird issues while using Unity 7, you can switch back to GNOME.
Install Unity 7 in Ubuntu 17.10
Open a terminal and use the command below to install Unity in Ubuntu 17.10:
sudo apt install unity
It will download files in size around 150 MB. Nothing else needs to be done.
Switch from GNOME to Unity in Ubuntu 17.10
Restart your system. Now, at the login screen, you’ll see a gear symbol. Click on it and you’ll see various options to switch to Xorg from Wayland. You’ll also see the option to switch to Unity. Just select Unity here.
Log in and you’ll see the familiar Unity desktop environment. The Unity version thus installed is Unity 7.5.
If you want to switch back to GNOME desktop, just select the option Ubuntu or Ubuntu on Xorg.
Remove Unity from Ubuntu 17.10
If you decided to stick with GNOME, you may perhaps want to remove Unity. Before you remove Unity, switch to GNOME.
And after that, use the following command to uninstall Unity:
sudo apt remove unity sudo apt autoremove
I hope this quick tip helped you to use Unity in Ubuntu 17.10. Personally, I see no reasons for going back to Unity. It’s certainly not one of the things to do after installing Ubuntu 17.10. What reasons do you have in mind?
