This bug also affects me with a fresh install of Ubuntu 20.10 beta. The
kernel is 5.8.0-20-generic. If I hit esc when it is stuck on booting, I
can see it is waiting. The boot message is too cryptic for me, but
maybe someone else has an idea. I'm using a Lenovo too (Yoga 260).
Here is a photo of the boot messages.

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.
