Description harish.hyma 2017-10-12 09:05:14 UTC 
As the title suggests, the external monitor shuts off when laptop lid closes. I believe the laptop goes into suspend more. The correct behaviour would be to disable the suspend function when an external monitor is connected.

I further observed that the correct behaviour happens on a fresh login and this persists after login. However, its a different story if I unplug the external monitor and close the laptop lid. When I reopen the lid and replug the monitor, the problem starts. The external monitor shuts off when laptop lid is closed.

This problem only seems to exist in wayland session and not Xorg session.

I am using gnome 3.26.1
Linux LTS 4.9.51

I am seeing similar behaviour.  However it persists even when I tell GNOME not to go to sleep on monitor close when power is connected (shouldn't that be the default?)  Off-topic, but that setting is usually but not always respected, and I have not yet found the pattern.  The way I solve this is to open the display settings with the laptop screen open and make the external monitor the default.  This setting is remembered across undocking and re-docking my laptop, but not always respected: I often have to disable and re-enable it to make it take effect again.
