About Powersave Tweaks Conversation

Issues & Assistance Newbies
1

Hello Garuda community... Im not "New" or "Newbie" in the linux world but when i started looking for the "perfect" system i choose Garuda as my base for this "perfect" system.

So i came across something that actually confuse me a little bit it looks "simple" but as what i mention before im looking for the "perfect" system as possible on low-end "AMD" laptop...

What im asking here is not an real "Issue" but an "Assistance" by providing your opinion and feedback about the "Powersave Tweaks" with the packages and services "Garuda Assistant" provides...

For example and really what makes me open this "conversation" is those packages:

  • Power-profiles-daemon
  • Auto-cpufreq
  • Thermald
  • Or maybe something else ??!

Intel-undervolt not included because im using AMD Cpu.

I read about these packages but really i want a real feedback from someone using them or someone just know how they work with real PRACTICAL use to get the "best?" performance without destroying the battery life.

And last thing... before someone send "Arch Wiki" link please consider give some opinion or kind of recommended option for my hardware.

The packages are fine, they do what they are meant to do and they work well enough. That is why they were included in the Powersave Tweaks bundle in the first place.

I would suggest placing less value on the opinions of others, and focus more on testing the tools for yourself to come up with your own conclusions. Everyone here is using different hardware, so the same tool can work really well for one person and be less effective for another.

Since you are using AMD, I would also investigate using the P-state driver, which can enable very significant power savings. It has been discussed here in this forum, for example here: Discussing Linux kernels for Garuda Linux - #6 by Austin

See also this lengthy discussion from another forum: How to use AMD P-State in Linux 5.17 - Kernel & Hardware - EndeavourOS

The ArchWiki is arguably the best source for Linux documentation of all time. Typically when someone links to an article, it is because it contains useful information relevant to whatever you are trying to learn about.

If you are interpreting linking to the wiki as dismissive or condescending, I will suggest you are misreading the practice. It is usually meant to be helpful.

Garuda's tools are intuitive so that the user just clicks and starts using them, for example Thermal PowerSave are kernel modules I understand.

If you want more efficiency for your laptop that you said has an AMD processor, I recommend that you compile a kernel on a multi-core machine with AMD-specific hardware and better consumption.

But for that you have to read the documentation and know what to touch and what not to touch in the kernel but the least you should do is put AMD Processor instead of the generic one and see the power options.

First thing i really appreciate your reply thank you, I was confused about the fact that you cant install them in the same time so "what they do ?" i read about them in arch wiki and understand why and how they work, and i was using "TLP" before... however i agree with "HARDWARE DIFFERENT" thing so i asked about practical use for these tools...

I know you cant tell anything from people opinions but still its like pointing me to the direction...

For P-state driver i will check it and really again i appreciate your effort & time writing this reply.

The "ArchWiki" indeed the best source for linux in general and arch to be specific... But if you read my message again i dont mean "DONT SEND" just consider give recommended that can point me to the right direction.

Thanks for replying but i really think you miss what im looking for. :sweat_smile:

I find what i was looking for, i will mark this as solution.

Please describe your solution for the benefit of others, then mark the solution.

As you mention before you need to do your own tests to decide whats the perfect solution for your hardware.

For me im using low-end HP laptop (HP 255 G6 Notebook) With (AMD A6-9225) CPU With (RADEON R4).

I Start by removing power-profiles-daemon that comes pre-installed with gnome edition and replaced it with auto-cpufreq... And keep in mind that thermald & intel-undervolt does not work with AMD chips.

Then i installed linux-lts and start using it instead of linux-zen not becuase i had any issue with it but just linux-lts give more stability and reliability for the laptop.

I did not configure anything just auto-cpufreq works good out of the box.

And i removed unused services & packages from the laptop.

Last thing AMD P-State work only with "zen based" (Zen 2 and newer) cpus. So im using the default acpi_cpufreq.
