Can't boot Ubuntu 18.04 from USB

Question

I created a Linux Live USB key with Ubuntu 18.04 and turned off Secure Boot on my Surface Laptop 3, but whatever I try it just fails to boot! :-(

Regular boot (has "quiet splash" option)

-> MODSIGN: Couldn't get UEFI db list

Boot in compatability mode (has "nosplash" option)

-> hdaudioC0D2: Unable to bind the codec

No success with other versions of Ubuntu and Linux Mint I tried either. I tried modifying the boot options manually but I'm not sure how to turn off or choose a different audio driver/codec.

Regular boot after removing "quiet splash" option

Laptop starts getting loud and overheating after the line

[ OK ] Started udev Kernel Device Manager.

Regular boot after replacing "quiet splash" option with "text"

Either the same as above happens or I get this output:

A start job is running for Set the console keyboard layout (13s / no limit)
Kernel panic - not syncing: Timeout: Not all CPUs entered broadcast exception handler

Does this answer your question? MODSIGN: Couldn't get UEFI db list Couldn't get size: 0x800000000000000e and Ubuntu 19.04 Freeze at loading DELL E6430 i5 - nomodeset didn't work well — Melebius, Feb 04 '20 at 12:08

@Melebius The "noapic noacpi nosplash" thing DOES make it boot (which is weird cos compatability mode includes the same options) but it's completely unresponsive both to built-in mouse+keyboard+touchscreen and USB-connected mouse+keyboard =/ — xjcl, Feb 04 '20 at 18:56
@Melebius I'll try tomorrow with a USB hub (for connecting mouse, ethernet and live usb), I think that might work! — xjcl, Feb 04 '20 at 19:58
So I had one successful boot but I either keep not getting into the GUI or, if I do, Cinnamon keeps crashing so I just endlessly restart it — xjcl, Feb 04 '20 at 20:05

What ended up working for me was

When booting, edit the command line (press e) to add noapic to boot options
Use Ubuntu Mate instead of Linux Mint because Cinnamon kept crashing
Install kernel debian-test-2 from here so keyboard touchpad etc. work
