I have an old laptop Lenovo E330, running Xubunu 16.04
I have connected 2 external displays to it, one with VGA, and other with HDMI cable.
I'm trying to write a simple command to extend my desktop to two external displays, the lid will stay closed, so i will run only 2 display simultaneously.

The command should be something simple like one of these.
xrandr --auto --output VGA-1 --mode 1920x1080 --right-of HDMI-1
or
xrandr --output LVDS-1 --off
xrandr --output VGA-1 --mode 1920x1080
xrandr --output HDMI-1 --mode 1920x1080
How should the correct script look like ?
Is it possible to enable laptop screen after I disconnect the external displays? Because currently it stays of even when I disconnect the external displays and restart the system ;(
Best Answer
You have to make two scrips to achieve your goal.
one to switch both external displays on and turn off your laptop display.
and the other to revert the change made by script one.
So create
script1.sh
and make it executable with following contents.and
script2.sh
with following contents and make this too executable.You can run the
scipt1.sh
after connecting the external displays and you have to run thescript2.sh
before removing the external displays.Note that the above method will mirror your screen to two separate screens at the same time. And if you need a separate screen rather than mirroring, you can use either
--left-of
or--right-of
option and provide device names accordingly.And also you can check if your hardware supports three displays at the same time by turning on the laptop display along with the two monitors.
