Raoul,
1. If you believe something has crashed then please follow these
instructions:
https://wiki.ubuntu.com/Bugs/Responses#Missing_a_crash_report_or_having_a_.crash_attachment
2. If removing "splash" solves the problem for you then we should
probably mark this as a duplicate of bug 1871641.
I can reproduce the issue on Lenovo T580.
Remove "quiet splash" can make the boot process reach to GDM.

Title:
Lenovo X1
Hi Raoul,
yes, your probably right it is not exactly the same. I overlooked in
your initial post that the problem happened before grub and the title
sounds so much like my problem. I think I assumed from here

Hi Maria,
I don't think your issue is the same I got. Note that my problem happened with
or without the dock, and I wasn't even reaching grub. That's the big difference
here. If you lose the video after grub, than your problem is elsewhere, and my
suggestion is to boot without "quiet splash" on
Hi,
I think what I experience on my Thinkpad T460s might be the same bug. I
do not have a dock but if I boot with an HDMI cable attached I get stuck
after grub - at the screen with the Lenovo logo and a spinner.
This only happens, if I choose "Single Display" in the displays setting,
using only
Do you have any suggestions about what could be the difference here?
Since I didn't do a fresh install, but an upgrade from 19.10? Without
that xorg.conf there's no way to see X.

Hi,
I tested it with fresh install 20.04, then install nvidia-driver-440.64.
Then everything works fine.
Usually no need to use custom conf by nvidia-xconfig.
But prime-select nvidia is a must.

Hi there,
I wanted to add that I've tried the Thunderbolt dock and everything seems to be
working as expected, even if there's a lot more of fan noise while the laptop
is attached to the dock (maybe I'll open a specific bug on this issue).
For this bug I don't think there's only one thing to
I was able to get LightDM (or GDM) with hybrid graphics only by manually
specifying an /etc/X11/xorg.conf file like follows (I generated it with
nvidia-xconfig and then made manual modifications following this [1]):

Hey AaronMa,
What do you mean with "found that LID close until the BIOS logo show, unless
the laptop will shut down."?
So you tested using the HDMI cable directly attached to the laptop and
everything worked even with something attached to the thunderbolt port?
Which kind of docking station are
Tried the steps to boot with LID close.
found that LID close until the BIOS logo show, unless the laptop will shut down.
Then all work good. GDM shows on external monitor.
Test with typec/HDMI/thunderbolt-dock-typc external monitor, thunderbolt dock
is always connected.
BIOS should be default
Just a follow up with my investigations in the issue, that might be
useful for users in a similar situation.
The problem related to grub not loading and fans lifting with no
