I use my smartphone regularly to login on servers of mine with SSH. This works really well, but obviously you have less width than with a normal computer screen.

Some tools, like w, will not work with this limited width and give you a message like 

w: 60 column window is too narrow

Being a sysadmin, I don’t like to be told something just can’t work. So, a little trick to make it work:

 w | cat

This will have w output it’s text through stdout to cat and cat just outputs the text to the console, no questions asked.

Yesterday I have installed Ubuntu 16.04 LTS on my laptop to try it out.
While overall the experience is quite good, I found that notifications were broken for apps like slack and atom.
Following the issue found on github, I have found the following workaround to work for me:

Add the following line to /etc/environment ( edit as root ) and reboot ( or logout and login )
