Lenovo Legion 5 15IMH05
$ uname -rv
5.11.0-34-generic #36~20.04.1-Ubuntu SMP Fri Aug 27 08:06:32 UTC 2021
NVIDIA Driver Version: 470.63.01
Had the same issue for some time, until I've "fixed it" recently. The
problem appeared out of nowhere after some update. Booting with attached
external monitor no matter if attached to HDMI or to DP over USB-C
resulted in total freeze during Ubuntu splash screen (for me worse then
BSoD from the rival product, couse no feedback what's going on...).
The problem seems to be connected with Nvidia proprietary drivers. From
what I remember it didn't occur when the nouveau drivers were installed.
Also it only affected the "hybrid graphics" mode (the "dynamic graphics"
setting in the UEFI). The "discrete graphics" mode has another issue
(brightness control does not work).
What finally has fixed it for me was the purge of all nvidia packages
and the driver reinstallation.
$ sudo apt-get remove --purge '^nvidia-.*'
$ su
# for FILE in $(dpkg-divert --list | grep nvidia-470 | awk '{print $3}'); do
dpkg-divert --remove $FILE; done
# exit
$ sudo apt-get install -f
$ sudo apt-get autoremove
$ sudo apt-get clean
After that reboot the system and install a proprietary Nvidia driver.
I hope this helps somebody.

Hi,
I had also same problem (after update to Ubuntu 20.04, had only blank screen on
my monitor), but recently found a 'solution' accidentally! MAYBE, it is the
same problem like mine!
My monitor is being connected via 'D-Sub' and 'HDMI' cables. It seems, separate
monitor instance is created in display settings ("Single Display") for each
connection type and you won't see anything in the monitor if you had selected a
wrong monitor instance (non-HDMI). In my case, I had selected 'D-Sub' monitor
instance and 'HDMI' output didn't work or I had blank screen for HDMI input.
Seems now I have selected the correct monitor instance for HDMI. So, maybe you
also had the same issue that you had selected a 'non-HDMI' monitor instance!

Find a solution. Clean installation of Ubuntu 20.04 works with Linux kernel 5.4.0.26, after 'apt upgrade' kernel will be upgraded to v5.4.0.29.
