I downloaded the plucky-desktop-arm64.iso daily build to attempt to install a dual boot of Windows and Ubuntu 25.04 Beta. The USB drive boots grub fine and selecting “Try or Install Ubuntu” is selected. The screen will go black for a bit then reboot into windows. I did try removing quite splash from boot parameters and see the following.
I did disable secure boot from inside the BIOS.
What additional information can I provide to help with beta?
It’s helpful if you’re specific…
The current daily is dated 20250410
where the beta ISO was dated 20250326.7
but what did you actually test?
If you file a bug report on launchpad that detail would be available, alas not being able to boot the ISO would make it difficult to run apport tools.
Reporting your actual attempted test (with links to bugs) on the ISO QA tracker would help, especially as that allows you to record the test against the specific daily you used (currently unknown), and link the test with actual bug reports (on launchpad) which improves tracking.
I tested the daily build “2025-04-10 07:34”.
I don’t feel as thought I have enough information to submit a bug report. I tried to force grub to drop out a debug log. But that just resulted in the picture I shared. Are there better ways to help understand why grub can’t boot into the live os?
I will add the attempt to ISO QA tracker.
thank you
Each model of Snapdragon X Elite laptop requires its own DTB file (or that from a similar machine). If you don’t find your laptop in this list then please add to it.
My laptop is on that list, just added my service tag as many others did.
You might also find this thread valuable…
@mwehner which laptop and exact model is this? Also X Elite or X Plus configuration? and possibly which display if it is a T14s.
Dell Latitude 7455
Processor: Snapdragon X Elite - X1E80100
GPU: Qualcomm Adreno X1-85
Sorry also only running windows on it now, but will dig for anything that will be helpful.
So the problem is that there is no upstream device tree for the Latitude 7455 yet. Others in Bug #2084870 “[X1E] Add support for Dell Latitude 7455” : Bugs : ubuntu-concept seem to have had success by loading the xps dtb but I would generally not recommend that unless you know what your are doing.
Unfortunately that means we will have to wait until the device gets upstream Linux support.
Totally fine with waiting am willing to help out as I can.
Also by upstream Linux support would that be from Qualcomm or Dell ?
