If you’re willing to test, though, I could provide an image to boot the thing, but its not an installer ISO.
Oh, yeah it is the x1p42100… I saw a device tree named x1p42100 on the image, I also tried that but it didn’t get me any further. Is that something under development?
I’d be happy if you could send me the boot image and if you need some feedback on it or something i can try.

Thanks for the hint. Indeed, it did load the non-oled device tree by default. With the *-oled.dtb the brightness control works on the t14s 64GB OLED.
sudo cp /lib/firmware/6.15.0-rc1-jg-0-qcom-x1e/device-tree/qcom/x1e78100-lenovo-thinkpad-t14s-oled.dtb /boot/dtbs/6.15.0-rc1-jg-0-qcom-x1e/qcom/
I’m not sure which symlinks are actually needed so I manually created all three.
$ ls -l /boot
dtb -> dtbs/6.15.0-rc1-jg-0-qcom-x1e/qcom/x1e78100-lenovo-thinkpad-t14s-oled.dtb
dtb-6.15.0-rc1-jg-0-qcom-x1e -> dtbs/6.15.0-rc1-jg-0-qcom-x1e/qcom/x1e78100-lenovo-thinkpad-t14s-oled.dtb
$ ls -l /boot/dtbs/6.15.0-rc1-jg-0-qcom-x1e
x1e78100-lenovo-thinkpad-t14s.dtb -> qcom/x1e78100-lenovo-thinkpad-t14s-oled.dtb

Well, the image for the Acer Swift Go 14 is downloadable now. The tests I could do were very limited, but it appears to do what its supposed to - though on my ThinkBook 16 you won’t see much 
Please write the image via Rufus or disks to a 16GB+, fast USB stick or external SSD. Also, please use the USB type-a connectors, type-c is problematic with loading the adsp firmware (which the image will attempt to do). Also, secure boot needs to be off, and the Windows partition needs to be unencrypted. Would be nice to hear if it works. For further discussion, please open a thread here.
FWIW, the Acer image booted the Samsung Galaxy Book4 Edge with the Snapdragon® X Plus X1P-42-100. Was able to boot but not install. Wasn’t expecting much but this thing has been bricked since a Windows Update a couple months ago and was happy to see something

oh that’s exciting, I didn’t know the galaxy book would get that far. Do you have an error log to figure out what went wrong in the installer maybe?
I wasn’t able to browse the image to get those files. I can say the keyboard wasn’t functioning and was using a USB but my best guess here was it wasn’t going to get past the keyboard. Through USB, I did have Ethernet, the image, KB and mouse all working.

I think after a failed installation you should get a new partition on the usb that holds the installer logs.
I tried different methods for burning but no new partition on the USB after failure. No log files to see. This is the last thing Ubiquity showed at the crash.
how unexpected 
Anyway, there is a dtb for the galaxy book 4, just not for x1p42… And the nature of the image is to support just one dtb. And re installer: There is only the one for preinstalled desktop. For it to work you need an unencrypted windows partition.

We very much dream about Ubuntu on Surface 11 Pro. But unfortunately, she has not yet been loaded there at all (including 25.04 Daily)

Surface 11 is a real issue. No data, Microsoft doing things very differently for peripherals. Without help from Microsoft you’re basically getting nowhere.

Keeping an eye on your progress, having the exact same t14s 64gb OLED. What I don’t fully understand from this whole thread is: where do I see if some of the manual changes everybody is doing here are getting in the iso download, which seems to be updated regularly. I’d love to daily drive this, but it feels a bit too early still. But love to keep an eye on the progress.
It was an interesting little experiment. Have had this tab open for weeks watching the progress. Samsung and Microsoft do not provide an iso to restore the machine so no Windows to put on so I wait on Linux or them so I can put a working system on and dump the laptop on ebay or something.

I think there is one now https://www.microsoft.com/en-us/software-download/windows11arm64
This should work on all X Elite machines

Depends. Some of the changes get upstreamed into mainline Linux, sometimes I cherry-pick the commits to our tree if I think they are likely to be included in mainline. Others are device specific and might need more work before we can roll them out for everyone. Loading the OLED device tree for example is something we know how to do manually, but if we changed the default we would break all the non-OLED users.
Currently our update rate has slowed down a bit because everyone is busy working on Ubuntu 25.04, which is scheduled to release on Thursday. After that we will have more time to focus on the more experimental things in the concept image again.
The best place to watch for your particular device is probably the tracking bug at Bugs : ubuntu-concept. I am also trying to share any major changes for each update as a comment here on discourse.

Question: since the official 25.04 ISO is releasing today, which ISO should I download? Correct me if I’m wrong, but as far as I understand, the official ISO still lacks some working features that will be addressed in the ISO available here. Will the official 25.04 version receive fixes for the missing features through updates once they’re solved, or should I continue using the ISO from here?
My recommendation would probably to do a do-release-upgrade and be done with it. Worked nicely a few times here.

25.04 does work for most parts but it is lacking support for a few things that caused regressions in other machines. It will also be mostly stable over the lifecycle of the release with the exception of bug fixes. I plan to continue concept development with more frequent updates in the ppa for 25.04 once the release is out.
As @glathe says installing the concept and going to plucky via do-release-upgrade -d seems like a good option.

I want to upgrade to 25.04, and tried do-release-upgrade, but it complained about not all updates yet installed of 24.10.
However, I run into a version conflict I cannot understand how to solve.
The following packages will be upgraded:
grub-efi-arm64 grub-efi-arm64-bin grub-efi-arm64-signed
3 packages upgraded, 0 newly installed, 0 to remove and 0 not upgraded.
Need to get 2122 kB of archives. After unpacking 17.4 kB will be used.
The following packages have unmet dependencies:
grub-efi-arm64-signed : Depends: grub-efi-arm64 (= 2.12-5ubuntu5.x1e3) but 2.12-5ubuntu5.x1e4 is to be installed
Not sure how to proceed. Tempted to just replace the version name in the ubuntu sources list and do a manual dist-upgrade. Ha.
Tried with removing the tobhe PPA’s, but still complaining.
Ah, solved it for now by disabling ‘extras-ppas.list’
