laptop monitor shown when lid is closed

alphadog · 05-01-2014, 01:37 PM

As a follow up, the laptop display is off - with lid closed, or using magnet to fool MBA into thinking lid is closed - but something in displaylink driver is not letting MBA realize it is connected to just external monitors.

Works fine if one monitor is connected via displayport. I really don't want to swap over to all thunderbolt, but this is frustrating.

Moved back to one displaylink and one displayport monitor - i only see 2 monitors in the monitor setup now - so having an external displayport monitor tells the laptop to shutoff the laptop screen when lid is closed - not show it in the list.

Interestingly the missing icon issue is back in the menu bar - but it is the displaylink monitor that is missing the icons - only for chrome notification. The apple icon is on both.

Also, before doing this, i plugged in the displaylink dock with lid shut..... bad mistake. locked up my laptop and only a hard power off would fix it.

Hi alphadog,

Clamshell mode can only be triggered with at least one external screen connected to the built-in GPU. This is a long standing OS X limitation, I'm not aware of special settings or workarounds.

The lockup after plugging in the dock is very worrying, we'll try to reproduce on our MBAs.
