You are very kind but this thread is my issue and always is, blank screen after install. I don't have a second monitor so the solutions I have found wont work for me. Having to have a second monitor or dissect your laptop are not viable for me (and shouldn't be for anyone). My laptop is a Dell Inspiron 7586 with a 4k screen. I need the 4K for my eyes. I write, so I need crispy text when working for hours. I have already tried all the other stuff like legacy boot and a myriad of other Bios changes to no avail. So I think it is time to give up until I can buy a Zorin or other linux laptop off the shelf.
