A fully fonctional and good-looking linux for less than 256mb of ram
Get the "mini.iso" image from archive.ubuntu.com
Just flash an usb drive with it as follow.
sudo dd bs=4M if=mini.iso of=/dev/sd<?> conv=fdatasync && syncYou have to download the server image from cdimage.ubuntu.com
Use a clean Fat32 usbdrive where you copy the content of the mini.iso image from the legacy boot section and add the EFI folder from the server image you just downloaded.
You should be all set to boot from the usbdrive.
If you're using only Ubuntu on this computer, clear all keys from secure boot before installation and add the "shim" pe executable to the trusted boot chain after installation.
Do it as usual and be careful to not select any additional packet to be installed on the system. 'member that the swap partition is depreciated, Ubuntu will now use a file if it's not present.
Press shift on boot to access grub and e to edit options.
Remove $vt_handoff from the linux line and press f10 to boot.
Once logged, edit /etc/default/grub and remove quiet splash from GRUB_COMMAND_LINE_DEFAULT.
Update grub
sudo update-grubInstall required packages ( edit accordingly )

Put your iptable scripts /usr/lib/networkd-dispatcher/routable.d/00-iptable-flush:
#!/bin/sh
/sbin/iptables -F
/sbin/ip6tables -FBlock anything goining on ith chrome mdns server for example /usr/lib/networkd-dispatcher/routable.d/50-iptable-mdns :
#!/bin/sh

/sbin/ip6tables -A INPUT -p udp --sport 5353 -j DROP
/sbin/ip6tables -A OUTPUT -p udp --sport 5353 -j DROPMake them executable:
sudo chmod +x /usr/lib/networkd-dispatcher/routable.d/00-iptable-flush
sudo chmod +x /usr/lib/networkd-dispatcher/routable.d/50-iptable-mdnsThen execute sudo netplan apply to connect
First of all we need to run it automatically each time we login.
Let's edit ~/.bash_profile and add the following to it:
if [[ -z $DISPLAY ]] && [[ $(tty) = /dev/tty1 ]]; then
startx
fiLet's edit ~/.xinitrc to:
export TERMINAL = "cool-retro-term"
alias open="xdg-open"
i3Now, start i3 by running startx command.
Use modkey+d and type the name of a program you wich to start
Open a terminal and edit "~/.config/i3/config" file
