  • [Tip to improve battery life]Amazing battery after setting some tlp options!

it's a bit confusing to refer to Ubuntu Budgie as "budgie" 😁

thanks, might have to explore tlp configuration on my laptop 🙂

      aquasp Just found this thread and would like to understand the differences in TLP seetings between SOlus and Ubuntu Budgie, but the link to your pastebin doesn't work anymore. Can you maybe refresh it?
      In current Ubuntu TLP package they seem to just provide the default tlp.conf which has no extra settings enabled/changed.

          palto42 The differences to default config are:

          • The scaling governor on battery is set to schedutil instead of powersave. In terms of savings they're almost on par, but schedutil yields much better performance. The governor on AC is set to performance.
          • Wifi power saving on battery is OFF
          • SOUND_POWER_SAVE_ON_BAT is disabled
          • USB_AUTOSUSPEND is disabled

              [deleted] Thanks, so assume suggested improvements have all been added in current package.

                I had another look at the current tlp.conf settings in the Solus package and some doubt if all of them are generally good.
                For example the change of the governor in AC mode to "performance" might not be desirable (at least not for me), since it sets the CPU permanently to max frequency as per [REF][GUIDE]Most up to date guide on CPU governors, I/O schedulers and more!.
                Also the changes to WiFi, sound and USB may not be generally required and may reduce battery life, so not sure why Solus package deviates from TLP defaults here.

                To me it seems that those non-default settings have just been maintained from older versions and may not be optimal anymore with latest release/kernel.

                  palto42 I agree that the AC governor should be in line with the governor Solus normally uses. TLP defaults to powersave on AC too. I don't remember why I set it to performance in the PR, it could've been an oversight from me.

                  The changes to WiFi, sound and USB date much further back and my guess for disabling those features is that they cause issues with certain hardware.

                      [deleted] It seems the default governor depends on individual setup, at least on my Lenovo it defaults to "ondemand" for both AC/DC.

                      On T9939 Update tlp to 1.5.0 I commented to revert back to tlp defaults unless there is a good reason still.

                          palto42 As far as I know, Solus momentarily switches to performance during boot, then at the end of the boot it switches to something else.

                          The commit for disabling wifi power saving says "Attempt fix for wireless on battery by disabling wifi power save.", so I do highly believe the other tweaks follow the same rationale and hence are still adequate.
