Public bug reported:
Hey everyone,
just upgraded to 20.04 in my Lenovo X1 Carbon laptop and found myself in really
big troubles.
I always started my laptop pressing the power button and then closing
the laptop lid, because I'm using an external HDMI display. This worked
always well with Ubuntu 19.10. With 20.04 the system crash.
These are the actions that reproduce the problem:
1 - Boot the system, pressing the power button and closing the laptop lid with
an external HDMI display attached to the laptop;
2 - See on the external HDMI display the boot progress: BIOS loading and then
grub not appearing;
3 - Listen to the fans that are about to make the laptop lift;
4 - Press the power button to force off the laptop;
At this point the only way to have everything back is:
1 - Detach any external device;
2 - Detach the power cable;
3 - Wait 3 seconds or more;
4 - Open the laptop lid;
5 - Attach the power cable;
6 - Press the power button;
Without doing exactly as I written the laptop will not boot up, even if
I force power off, after starting it again, after the BIOS display, the
screen goes blank and the fans lift.
NOTE 1: I already disabled secure boot in the BIOS, and also selected
discrete graphics for the display (otherwise I'm not able to even start
X);
NOTE 2: the scenario is exactly the same with nvidia-driver-435 and
nvidia-driver-440;
NOTE 3: if I leave the laptop lid open, everything is just fine;
