I have a laptop with elementary OS 0.5. I connected my 27" TV with the HDMI cable on my laptop to use it as a monitor, I already did this in other distributions (ubuntu, mint, deepin) I access the screen settings of the elementary, set up my TV as the main screen, and uncheck the "Use this screen" option to disable the integrated screen of my laptop and click on apply. This does not work, my laptop's integrated display is still on. The only alternative I found is to use the command below in the terminal: xrandr -- output [MY LAPTOP MONITOR ID] -- off Works, but when I turn on my computer, these settings are not saved and I have to perform the procedure again. Is there any way to save these settings? So I do not need to manually turn off the integrated display of my laptop every time I turn on the PC? Sorry for my bad English. Thank you very much in advance.
