There are many users who still miss the classic Ubuntu desktop, that is, Gnome 2.X, a desktop that many liked due to, among other things, its top bar where we not only found the clock but also other elements such as the menu. We can correct this due to the AppIndicator ClassicMenu, an appindicator that will allow us to use the traditional Gnome menu in our Unity. We just have to install it and then move it according to our tastes, in such a way that we can recreate the old Ubuntu desktop.
ClassicMenu Indicator is an applet that is written in Python3 which makes it a lightweight and functional applet in the most current versions, compatible with the latest Unity versions and from many other distributions like Ubuntu Gnome.
How to install Classicmenu on your Ubuntu to get another menu
In order to install ClassicMenu we have to go to the developer's website or we use the enabled repository, for the latter we open a terminal and write the following:
sudo add-apt-repository ppa:diesch/testing sudo apt-get update && upgrade sudo apt-get install classicmenu-indicator
Once we have installed the applet, we have to insert it into the Unity bar and we can move it like any other Unity applet. Of course this Classicmenu is an interesting applet not only for recreate a nostalgic look but also to customize our operating system and make it lighter or lighter without losing functionality for it.
If you are nostalgic for Gnome 2.X this applet is important and must be in your operating systems, but it is not available for all versions of Ubuntu, that is, in a version older than Ubuntu 14.04, ClassicMenu will work with some problem or its operation is not very assured. Still there are many other methods and ways to get the classic Gnome 2.X look such as installing Ubuntu MATE.
Personally, I see it silly to install it in Ubuntu, but if you are not going to use the Dash, install Ubuntu Mate or Xubuntu for example, you install a dock and it is fixed.
«… Make it lighter or lighter without losing functionality for it.»
I don't understand why Ubuntu is going to be lighter by installing this menu.
No ... it's different ... personally I HATE the Unity Dash and its messy menu (it gives the idea that someone took the applications and threw them all together) ... but its dock has no comparison ... I have not found another that improves or equals it (not even the Windows 10 ... which is like the almost successful copy of the unity dock). The closest thing has been to use empty panels in KDE and modify them, but still ... Unity Dock is the best.
