    Most notable, UPower 1.90.4 fixes an issue around excessive disk writes and CPU usage. This bug report from four months ago noted high disk writes from the UPower daemon and that in the period of 12 hours around 7.5GB of data was written to disk...‚Äč
    Oh, yikes.

        This power save utility probably used more power than a system without any support for power management.

          Comes default on just about every desktop distro

            Couldn't remove it because of dependencies (gdm for example), but it's possible to disable it.

            Code:
            systemctl stop upower.service
            systemctl disable upower.service
            systemctl mask upower.service

              Yeah, that's what I think sometimes. From time to time I stare at htop and I can only see thermald or upower, so I wonder what would happen if I disable them...

                I don't know about you guys, but i never got into those power mode things and p-states and whatever.

                I have a shell script that uses cpupower to throttle the CPU, shuts down the NVIDIA GPU and hibernates the second HDD for when i want to have a silent laptop for internet browsing.
                I could never be bothered to research on how to make this "energy saving mode" stuff do the same.

                  There were still incoming events spawned from wherever...
                  Won't be able to test this until I fix my install. Managed to break both kernels at once, so I have a bit of work ahead of me.

                    This is what Windows does all the time in the background.

                    I am legit so sick of devs who write to the disk like it's their own backyard. Fuck off.

                    At least on Linux I can disable almost all of it and in worst case, if some dumb ass app still insists on it, I make the fucking file immutable. Get fucked.

                    GET OFF MY DISKS. KEEP YOUR STUPID LOGGING TO YOURSELVES.
