** 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

+ 
+ 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. We work around this by 
switching the main mesa provider snaps to channels built against a working mesa 
version.
+ 
+ Since 24.04 there is a dedicated mesa snap to handle those kinds of
+ situations, for 22.04 we have to hijack the gnome snap which also
+ bundles mesa.
