Before Ubuntu

I had installed windows 7 but would stop working after boot if there is no internet connectivity. After connecting to Ethernet port it would stuck forever. Sort of memory LOW problem.

After Installing Ubuntu

Installing Ubuntu was the same like others.But tweaking it to use lowest memory(RAM) possible was my challenge. Without tweaking it would again act like windows 7 and stuck at some point.

Things i did:

My first job was to remove the packages that were using the memory unnecessarily First of them was the Ubuntu default desktop environment. I always hate unity. Don’t know why but i have always hated that.

sudo apt remove unity

This couldn’t uninstalled unity-greeter package so had to manually uninstall it.

sudo apt remove unity-greeter

I also removed gnome packages.

sudo apt remove gnome- *

The next thing to do was to remove the Ubuntu display manager which is in fact lightdm by default.

sudo apt remove lightdm

And a quick autoremove of several packages that were no longer needed.

sudo apt autoremove

All combined

sudo apt remove unity unity-greeter gnome- lightdm* sudo apt autoremove

Do not reboot, otherwise you would not have your desktop environment.

Start installing

Do a quick update

sudo apt update

Installing the desktop environment first

sudo apt install i3

As i removed default display manager, i somehow needed to start i3 when X starts, so:

cp /etc/X11/xinit/xinitrc /.xinitrc emacsclient .xinitrc

And add the following line at the end of the file to start i3 when i start my X server manually.

exec i3

Now install some useful packages

sudo apt install gnome-terminal ranger tmux openssh-server git htop sudo apt autoremove reboot

And a clean reboot.In the tty terminal enter your username and password.Then, u will be left in the shell(probably bash shell).Enter:


This starts the X server. And also the i3 window manager.

Testing the system

Setup a xampp server Start and use firefox Check for information using htop

This that can be done:

Remove network manager and assign static ip.
