I hooked my laptop to an external monitor and had a lot of fun with it.

Problem now is, Peppermint still thinks there is an external monitor (which is not there anymore) and leaves the internal display black.

Only fix is to boot through the rescue prompt - which leaves me with a distorted 1024x768 resolution. But at least the internal display is back again. I cannot seem to change anything in the Monitor Settings dialog from the rescue-booted OS. When I boot again normally, I get a black screen again.

How can I switch back to the internal display? :shock:

Boot to another kernel and see if it works.
Also, a lot of laptops have a monitor toggle switch using F_ in conjunction with the function key (FN). For example, FN + F4. Finding the right combination for your laptop might be of some use to you.

I agree with mac: I use Peppermint 4 on a laptop that is used to display presentations through an external beamer during lectures. Sometimes, actually very infrequently, I also must use my FN + Fxx keys to toggle around for the appropriate display combination (the previously used combo having mysteriously vanished since my last reboot).

However, like I said, this happens very infrequently, but can be unnerving when I forget that it is a simple matter of toggling around with FN + Fxx. When toggling, be sure to wait a few seconds before toggling again: on my not-so-new laptop the response to toggling is rather slow ... :roll:

Good luck,

I have FN keys, but they don't do anything...

This is Peppermint 3 btw.

Alternative kernel? I booted in to the "(recovery mode)" variant that is created by the Peppermint installer, which gave me the fall-back resolution (768p).

I am hoping for someone to tell me in which configuration file I can set the display manually.

Edit: Ah, OK - I'm back again! Some combination of recovery mode, setting the resolution in the dialog and rebooting did the trick...
