I am aware this issue has been asked before, but I have tried the common solutions like changing HandleLidSwitch=Ignore and removing GNOME screensaver and installing xscreensaver with no splash.

I am trying to use my laptop with two monitors and currently have the laptop set up so the internal screen is off. This setup works fine when I leave the lid open; but the open windows stop responding when I close the lid, although the cursor still moves and some tasks can still be performed (e.g. dragging windows).

Laptop is a Dell E7240.

Version: Ubuntu 18.04.2 LTS

Workable solution found:

Screenshot of finding LID node

1) Find lid switch node with 

cat /proc/acpi/wakeup

2) Unbind by echoing that node into the directory:

/sys/bus/acpi/drivers/button/unbind

3) Close lid

4) Restart display manager after lid close: 

sudo systemctl restart display-manager
