Some more info can be found here https://help.ubuntu.com/community/ServerGUI. I assume you start with a clean install of Ubuntu Server 16.04 (some modifications may be needed for older versions of Ubuntu). Depending on your needs you can do these:

Minimal GUI:

sudo apt install xorg
sudo apt install --no-install-recommends openbox
Run the command startx and openbox will start (you can open a terminal there and run any application you want)

# resize jpegs
for i in *.jpg; do sips -Z 2500 $i --out "./small/${i%.*}.jpg"; done

# convert to tiff with lzw compression
sips -s format tiff -s formatOptions lzw [file] --out [file]

# convert to jpeg lossless

Adding PIXEL/GUI to Raspbian Lite

These 'notes' were primarily intended for my own consumption but since there have been surprisingly many comments to it over the years I wanted to do some updates and clarifications. Thanks for all comments.

These instructions will require you to have connection to internet from your pi, WiFi, Ethernet or by some other means like a 3G USB dongle or something.
