[Bug 2084591] Re: [X1E] Galaxy Book 4 Edge Support

[irtix]

Ubuntu's initrds are a bit different than those found in many other
distros. To repackage manually:

unmkinitramfs old-initrd.img .
<add modules / firmware>

cd early
find . -print0 | cpio --null -ov --format=newc > ../early.cpio

cd ../main
find . -print0 | cpio --null -ov --format=newc > ../main.cpio

cd ../
zstd -19 main.cpio -o main.cpio.zst
cat early.cpio main.cpio.zst > new-initrd.img

To simplify things a bit, I have now added compiled versions here:

https://github.com/zensanp/linux-book4-edge/releases/tag/30-01-2026

Though, I would again recommend adding these to one of jglathe's IMGs as
opposed to modifying the concept ISO.  There is less risk messing up the
Windows partition, and you can easily recover the system if something
breaks.

Title:
  [X1E] Galaxy Book 4 Edge Support

Status in ubuntu-concept:
  Confirmed

Bug description:
  == Device Information ==

  IdentifyingNumber : 6T619FFX700282M
  Name : Galaxy Book4 Edge
  Vendor : SAMSUNG ELECTRONICS CO., LTD.
  Version : 2.1
  Caption : Computer System Product

  == Kernel Support ==

  Not booting, awaiting test feedback for latest change

  Original:

  With the release of the ISO image, there appears to be initial support
  for running Ubuntu on devices with the Snapdragon X Elite ARM64 chips.
  I own a Samsung Galaxy Book 4 Edge with a X1E84100 CPU, and I would
  love to get Ubuntu on this device. I cannot offer much in way of code
  contribution but I am willing to perform any testing necessary to
  progress towards getting Ubuntu running on it.

  As a proactive measure, I created a bootable USB with the Ubuntu
  Concept ISO image written to it. I was able to reach a Grub menu and
  used the "Try or install" option on grub. Afterwards, I reached a
  blank black screen for around 30-45 seconds before my laptop rebooted.
  I can provide media if that would help convey the behavior. Lastly, if
  there is any additional information I can provide related to this
  device I'm more than happy to oblige.

  Thanks,

  Patrick W.
