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

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 tomorrow is related to Thunderbolt. If I leave any kind of device (network adapter, webcam, whatever) attached to any of

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
