I just want to add that I have the same problem on my Asus N552VW. I have managed to make it work from day 1, so hopefully this can help someone until the proper bug fix is provided.
I have a laptop and an external monitor plugged via HDMI, everything is turned off. Simply turn on the laptop and load the OS, input your login/pass and get into system. Now close the laptop lid, then turn of the monitor. This are the only steps I can make an external monitor work with 20.04, kernel 5.4. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1871721 Title: Second Monitor on HDMI blank screen/blink screen with Nvidia + Intel & Ubuntu 20.04?
