I bought an officially supported and qualified laptop as recommended by canonical and the GPU drivers shit the bed at least two times an hour. Power management didn’t work. The battery got shitcanned after an hour. Just no. Lenovo T495 for reference.

  Exactly. That wasn’t specified when I bought it. It’s a regression.

    Are you saying that regressions only occur on Linux?
  - formerly_proven 5y ago
    Is it actually a regression or did it never really work in the first place? Hardware manufacturers are in my experience pretty unreliable sources when it comes to compatibility and I've had my fair share of issues even with 100% unmodified straight-from-the-factory machines regardless of OS. Edit: I also 'member Dell shipping some of their XPS laptops with Linux preinstalled despite them having missing drivers / functionality.

      It worked fine for three months until a kernel update.

        So you should be able to fix that by choosing an older kernel.

        And there goes the rabbit hole…
