Battery life under Linux

Linux energy efficiency, laptops and battery life

While linux distributions proliferate on servers and desktops (and even on mobile devices in the form of Android) linux desktop OSs running on laptops have often been the poor relation. Most prominently, it’s become somewhat accepted that popular fully-featured distributions like Ubuntu and Mint will have significantly higher power consumption, and worse battery life, than Mac OS – or even Windows. Keeping up with Windows running on the same machine is typically considered a good result.

This was much the situation I found for myself when running Linux Mint on my 2015 Macbook Air. The features of Linux Mint are excellent, and I much prefer the interface and flexibility to Mac OS. Indeed, modern distos like Mint are now by necessity generalised for many different systens, which inevitably introduces some degree of unwanted components (or “bloat”).

What I was interested in was whether it was possible to piece together a Linux system more minimally tailored to my needs, and optimised for the MacBook hardware – and so maintain the freedom and flexibility while regaining the battery life performance.

Macbook Air + Gentoo + LXDE

What?

Take a 2015-era, 11-inch MacBook Air. Strip off the proprietary software tailored exactly for this hardware and model. Install the most do-it-yourself Linux distribution there is.

Apple no more

First up, why (on earth) would I want to do this?

Review: Camille Paglia (take 2)

Provocations, Free Women, Free Men and Junk Bonds and Corporate Raiders: Academia in the Hour of the Wolf by Camille Paglia

For some reason I keep giving Camille Paglia’s Provocations another shot. I didn’t get any further this time before throwing it across the room, and reading bits of Free Women, Free Men I’m sad to say it too doesn’t hold up very well in hindsight.

To cheer myself up I read her long essay Junk Bonds and Corporate Raiders. It’s a bit silly in places, but is very funny and the targets (particularly academic careerism) are very worthwhile:

I’ve been on a Primo Levi roll for a couple of weeks, particularly his short stories. They’re tremendous.

Review: October Child

By Linda Boström Knausgaard (2021)

Saw it in the bookshop and I know I can only survive on Knausgaard blood.

Dreamlike account of the obliteration of Linda’s memories through an extended course of ECT in a mental institution, in a sort of fugue through mental states between unconsciousness, memory, dreaming, and awakening.

Review: If On A Winter’s Night A Traveler

by Italo Calvino

This is great fun – if perhaps getting a little wrapped up in itself by the end.

An anonymous reader keeps picking up books, becoming fascinated in the first chapter, before having the book lost, stolen, or discovering the whole thing is a mistranslation or forgery.

Calvino does an amazing job of writing a dozen absorbing first chapters with throwaway ease; the bits in between I wasn’t so sure about. It’s very “postmodern” in an obsessed-with-texts, the relationship between reader and writer etc. kind of way. Is this theme really the skeleton key to life? It’s pretty funny, but I get the feeling would be even funnier if all the characters weren’t cyphers.

Knausgaard #6: The End and amusing Reviews

Now reading Knausgaard #6. I think I’ve got a problem…

I have continued to enjoy them, but there’s definitely an aspect of comfort reading even in the boringness (not to mention Karl Ove’s amazing failures of judgement that make me feel a lot better about all my decisions).

Review: The Lies That Bind

By Kwame Anthony Appiah (2018)

This is wonderful, just so clear and wholesome in a discussion of a subject – identity – which can of course be pretty fraught.

It belongs to that rare class of writing where the language is so crisp and readable, you barely notice you’re being lead to some really philosophically interesting places. I particularly like his take on meritocracy, which is an idea that exercises me a lot. He does talk quite a lot about himself – but then he’s had such an interesting life and background, I hardly blame him.

Reviews: Modern African History

The Scramble For Africa by Thomas Pakenham (1990) & The State of Africa by Martin Meredith (2005)

The Scramble For Africa. This is just fascinating – surely one of the strangest few decades in history. Other than the pretty horrific behaviour of the colonists – who, perhaps Brazza excepted, were tremendously low-rent graspers and cheats (as well as plain brutal) – what most strikes me is how shoestring the whole business was. Regions the size of France “claimed” by a few dozen troops, etc. I’ve actually read this before – but the weird format (it’s all chronological, rather than by area) meant I struggled to piece together the whole arc of regions like the Congo. So I only read the central Africa sections in sequence this time, about half the book.

Review: My Struggle #2

A Man in Love By Karl Ove Knausgaard (2013)

I’m still really liking this, the mixture between the boring day-to-day and unexpected intensity is if anything even more pronounced and is still doing it for me.

I do feel like I need a bit of break from Karl Ove though – there is one heck of a lot of childminding in this one.
