Title says it all basically. I managed to get it to work once but as soon as I restarted the laptop it stops detecting the second monitor again. I don’t remember exactly how I managed to make it work but I recall had to something to do with Nvidia Drivers.
This time I tried everything shown here but couldn’t get it to work.
I’m running Ubuntu 20.04 and my GPU is a Nvidia GTX 1650 Mobile.
