I have a second monitor that I connect to my dual boot Lenovo laptop. I have had this laptop running in roughly this configuration for the better part of a year and never had a problem. Yesterday everything was working, I disconnected my laptop from it's doc to use it in the living room and it ran out of power before I managed to get it to a wall socket. This morning the system is not detecting the screen. I have checked the Windows partition and it has no issue. I have briefly looked at posts relating to this but most of those seem to be from install and do no address this situation.
I have run the apt updates and all that. My understanding is that everything was configured correctly, but I am out of ideas...
Any help would be great!
