I've reinstalled my laptop yesterday and decided to give Elementary another shot. Everything's working great and I'm loving it but now I have a big issue.
I connected the laptop via HDMI to an external monitor and I saw both just fine. I then made the external HDMI monitor the favourite/main one so the laptop one would turn off. Now I can't turn the laptop one back on!
If I reboot the system with the HDMI cable not attached it works just fine but if I connect it it still displays the external monitor only. From the system settings I see the laptop monitor but pressing the little switch makes it move where it should be "On" but it immediately goes back to off like if I couldn't select my laptop monitor.
I pressed the F5/F6/F7 keys on this ACER(E1-570G) and now if I have the HDMI cable attached the laptop monitor keeps flashing withot showing more than the cursor, if I de-attach it the laptop one works but obviously I got no external monitor.
What's going on? How can I go back to have the laptop monitor AND the external one working together again?
