One hopeful note: the developers for the Snapdragon X Elite are active on the kernel mailing list, and they are supplying patches for specific laptops, including the T14s. Now I run Debian, so i don't use AppImages or Snaps or Flatpaks, but I expect to have a fully functional T14s Gen 6 running Trixie when it is released as stable next year, assuming Trixie uses kernel 6.12 or (hopefully) 6.13.
