If you have a low-end laptop or an older desktop with Ubuntu installed, you may notice that it is something slow, normal. Linux distributions are light even in their heaviest versions if we compare them with other operating systems, but obviously they need resources to be executed like any other software. If you don't want to install Lubuntu or Xubuntu, the lightest flavors from Ubuntu because you like Unity, follow these steps.
To say that Unity, Ubuntu's default desktop environment has been created by Canonical to have certain similarities with the Mac OS X interface, in fact you just have to open the control panel on OS X and Ubuntu and compare ... Or take a look at it. look at the launcher, top bar, etc. And Unity is not one of the lightest environments, so it can consume between 300 and 600MB of RAM ...
Much of the RAM and resources consumed by Unity are directed towards the Lenses and Scopes, especially the video and music ones, so you could choose to delete them. Unity's 3D effects don't help improve performance either, so it wouldn't be a bad idea to use Unity 2D. The options to improve performance are many, there are programs such as zRAM or Preload, remove the apps that start with the operating system to speed up startup, optimize Compiz in Unity 3D, etc.
You can use the method you prefer, another option is install Unity Tweak Tool. You can choose to install the unity-tweak-tool package from the terminal, but in the Ubuntu Software Center you will also find it as "Unity Settings" if you do not want to or do not defend yourself very well with the console. Once installed, we can open the application. Of this new optionsWhich one are we interested in?
- Windows Administration -> General -> Disable the Windows Animation option and also in Texture Quality -> Fast
- Unity -> Launcher -> You can disable transparency and also disable icon animation.
- In addition to these, you can make some personalized configurations according to your needs and demands ...
OK, interesting
