** Description changed: [Availability] Currently in universe [Rationale] Very much like we did with the Lenovo Thinkpad X13s for 24.10 [1] I would like to add support for some of the new Snapdragon X Elite laptops in our coming release. Because arm64 is a bit special we need to ship a settings package containing tweaks and configs that make the installer "just work". This is based on the work I did for our Snapdragon Ubuntu concept image [2]. [Security] I don't expect any security impact. The package is mostly config files and should only affect this specific hardware. [Quality assurance] For now we will have to test manually. There are multiple developers who have access to hardware so that should not get in the way. [UI standards] [Dependencies] [Standards compliance] [Maintenance/Owner] Owned by the Foundations team. [Background information] The package provides 3 binary packages. - hwe-qcom-x1e-meta: This is picked up by "ubuntu-drivers --recommended" in subiquity and pulls - in ubuntu-x1e-settings + in ubuntu-x1e-settings - ubuntu-x1e-settings: A full set of configs needed to make a installation work. This includes - statically configured kernel command line parameters that would regress other devices + statically configured kernel command line parameters that would regress other devices - ubuntu-x1e-settings-nogrub: A safe subset of ubuntu-x1e-settings without the kernel command line. - On our live media we want those to be set at runtime depending on which device we boot on to prevent - regressions + On our live media we want those to be set at runtime depending on which device we boot on to prevent + regressions + + > please explain and give rationale for the "snap channels" in + > debian/ubuntu-x1e-settings.postinst, as this seems to be swapping out the + > whole stacks of GNOME/Mesa, which might lead to a different experience than + > stock Ubuntu. + > => snap refresh --channel adreno/stable --no-wait gnome-42-2204 + > => snap refresh --channel beta/kisak --no-wait mesa-2404 + + Since this is pretty new hardware we are facing problems with the dependency bundling model in snaps. Mesa in particular is problematic because it is closely tied to the hardware and kernel. + The hardware this package enables is not supported in mesa prior to 24.10, so the "default experience" would be that nothing works.
