[solved] Connecting laptop to external monitor

Post by jeenuv »

In my setup, there's an external monitor connected to the laptop, which I use as my primary screen, and switch off the laptop screen when it's on desk. It all works fine.

It used to be the case that, until I had Linux mint 17+ a month ago, when I pull the HDMI cable, the laptop automatically switched to its own display; and when I plugged the cable back in, it switched to the external monitor and powered off the laptop screen.

I upgraded to 18.2 last month, but the experience is different. If I pull the HDMI cord, the laptop display doesn't switch on automatically. I've to explicitly press the switch display button on the laptop keyboard (Fn+F6, FWIW). Does anyone know if I'm missing some configuration?

Found the solution: mark the laptop monitor as primary, yet set it to "Off". That way, it automatically turns on when I disconnect the HDMI.

I now doubt whether the solution I posted works. I mean it did work at the time of posting, but it's not reliable.

As a whole, I find 18.2 release not as reliable as what I had before (17+); if anything, it's made my system slower :(
