Using Network Manager

First solution:

exec --no-startup-id nm-applet

but this might not work. I used this:

sudo apt-get install wicd wicd-client wicd-gtk 
sudo systemctl start wicd
sudo systemctl enable wicd
wicd-client &

wicd authentication WPA2 with MSCHAPv2 (eduroam)

From here you can find the template to place in /etc/wicd/encryption/templates. Edit /etc/wicd/encryption/templates/active by adding the new template's name and restart wicd-client.

If this still not work then ( from here ) do this below:

sudo apt-get remove --yes network-manager
sudo dpkg --purge network-manager-pptp-gnome network-manager-pptp network-manager
sudo shutdown -r now

ubuntu 16.10 dns problem

If ping 8.8.8.8 works and ping google.com not, try to check if systemd-resolved.service is running.

sudo systemctl status systemd-resolved

now stop and disable it:

sudo systemctl stop systemd-resolved
sudo systemctl disable systemd-resolved

Multimonitor

Usa xrandr command to get the list of available monitors. In my case, my primary monitor is eDP1 but will probably change for you.

To connect an external monitor just run:

xrandr --output HDMI1 --auto --right-of eDP1

this will connect an external monitor connected to your HDMI1 port, right of your primary monitor and with automatic resolution. To set a custom resolution use the following instead of --auto

--mode 1440x900

To turn off some monitor use this command:

xrandr --output HDMI1 --off

i3-sensible-terminal

/usr/bin/i3-sensible-terminal is a script that checks if some terminals are installed and execute the first available.
