Title:
Ubuntu 20.04 HDMI connected, no boot

Status in linux package in Ubuntu:
Confirmed

Bug description:
I have installed Ubuntu 20.04 (using the image created on 20 april) on
my Dell XPS15 9560. This laptop has a Intel / nVidia combo.

The problem i am facing is that when i have an external monitor
connected to the laptop through the HDMI connector of the laptop,
Ubuntu does not boot and hangs on the splash screen. I have not found
any way to get logging on any kind.

Before i was running Ubuntu 18.04 and did not have any problems with
the monitor and HDMI cable. After boot is finished (without monitor
connected) inserting the HDMI cable works fine and i can use the
monitor and laptop screen without any problem.

I have installed the preferred nVida proprietary driver. Also it does
not matter if booting with nVidia selected or Intel selected.
