Hi to all comunity thanks to install this marvellous system in my netbook intel atom n455 whith 2 GB RAM and now explain how to tune up and make more faster this system.
1.- Install updates once you are install the system.
2.- Install preload and prelink.
3.- Install zram-config.
4.- Install bleachbit.
5.- Install deborphan.
I recomended use the terminal to update and upgrade the system because its more efficcient because more times crashed and errors in the apt variable.
How I use deborphan, in a terminal windows use this:
sudo apt remove --purge `deborphan --guess-all`; sudo apt remove --purge `deborphan --libdev`; sudo dpkg --purge $(deborphan --find-config)
Every day or every week or every month use this:
1.- sudo apt update and sudo apt upgrade
2.- execute bleachbit and bleachbit root
3.- use deborphan and localpurge.
Deborphan determines which packages do not have others depending on your installation, and shows you a list of these packages.
While Localpurge is a utility that deletes all manuals and help that are in a language other than those configured through it within our Operating System.
Other thing use lightweights themes icons to maximize the system
Have a nice day.
