I have this laptop, and installing 20.04 lts give me a system almost impossible to use.
Then I have found: https://github.com/linux-surface/linux-surface/
And after it almost works, but the boot is problematic.
I can not login if I boot normal, I must select last kernel option, in recovery mode, then hit "resume" on the diagnostic screen, and then the login is visible and the system works.
I have tried differents kernel version but nothing change.
Looking into logs, show me just a couple of more verbose error:
lug 22 11:06:17 natty-Surface-Laptop-4 kernel: Kernel command line: BOOT_IMAGE=/boot/vmlinuz-5.13.4-surface root=UUID=9a226104-1a23-4ead-9f83-9c32ef61303c ro recovery nomodeset dis_ucode_ldr

and

On "additional Drivers" for graphics nothing is aviable.
Any suggestion?
