Older Dell inspiron I think this issue, no sleep on power button or closing lid, started with plasma 6.2 update.

Anyway, I don’t think it’s the kernel but I don’t know what else could be the problem.

Sleep works from the start menu power/session but the shut down restart and log out options do nothing, no confirmation window nothing. I can’t believe I’m the only one with this issue.

There are big difference s in how power management has been done by Windows and Linux, so for laptops you are depending on vendor firmware. For 5 years or so, Dell has been pretty good about updating firmware on newer systems, and participates in the fwupd project.

  1. check for vendor firmware updates, both with sudo fwupdtool get-updates and Dell websites.
  2. Some models support acpi_osi=linux (or other “secret incantations”) to enable linux ACPI module.
