After a recent system update, **suspend (sleep) stopped working**. First I + suspected the NVIDIA driver to be responsible, it had been upgrade to version + 560. However, when I downgraded the driver, the problem persisted. Finally I + found a [thread][] on the Fedora Discussion forum which suggested to disable + ethernet in BIOS. Tada! That was it. Hopefully, with a future kernel or + firmware upgrade, I will be able to use ethernet again, as I prefer to have + cable-bound internet at home. The current linux kernel is 6.10, upgraded from + 6.9 just recently. + +2. Here's another [interesting report][techtipsy] from someone running **Linux on a P14S**, + albeit Gen 4 (mine is Gen 5) and with AMD and integrated graphics (I have + Intel with dedicated NVIDIA GPU). The author (Herman) also notes the battery + drain (even with AMD and iGPU) and the build quality which is somewhat below + the T series. Herman has also posted about [controlling fan speed with a simple + script][fancontrol], and I think I am going to tinker with it in the future, + because the following works on my P14s Gen 5 with Intel CPU and NVIDIA GPU: + + ```bash + # This is just a proof of concept, spin up the fan and spin it down again + # Run as root + echo level 7 > /proc/acpi/ibm/fan; sleep 5; echo level 1 > /proc/acpi/ibm/fan + ``` + [Darktable]: https://darktable.org +[fancontrol]: https://ounapuu.ee/posts/2022/09/26/minimum-viable-fan-control-script/ [Fedora]: https://fedoraproject.org/ [KDE forum]: https://discuss.kde.org/t/unable-to-start-kde-neon-plasma-on-core-ultra-nvidia-rtx-500-ada/18578 [KDE neon]: https://neon.kde.org @@ -202,4 +232,6 @@ keyboard really should be better, but hey, life is not perfect, is it?
