Can you name one thing that a NOOB-friendly Linux requires the command line for that a technically illiterate user can accomplish in MacOS / Windows?

Changing mouse acceleration settings is one I ran into, there was no option in the UI at all and google searches brought up config file edits that went completely over my head. I think it was on either Pop or Fedora KDE.

In windows it will come up by typing 'mouse' into start.

The "14 hours" is a huge exaggeration, but that's to be expected; every advertised battery life I've ever seen is a huge exaggeration. But I have to strongly vouch for this one; it's the first laptop I've seen that actually can actually last more than seven whole hours with Linux. Every other laptop I've tried lasts under four hours, even if it advertises twenty.

My XPS 15 9570 happily lasts 10+ hours, even though it's already few years old now. Running Arch with nouveau and nvidia card disabled

How about we also include how MS infiltrated the education system with hidden incentives and essentially forced training in a non-free user hostile operating system to multiple genrations of people? I think people had to learn Windows. They can learn Linux. The excuses are bs. Schools should teach unix/linux, and not proprietary systems. We should expect people to learn new things to be able to operate new tools. Tha…

It's all software really. Most people would be fine without Adobe or Microsoft Office or Google Docs. We don't need to train kids with GitHub, Sibelius or Dorico, the list goes on. Concepts don't require application-specific training and the FOSS options are largely good enough if not better than the proprietary competitors.

I'm wondering with the (permanent?) switch to work from home if laptop sales will go down. I've replaced both my personal and work laptops with System76 Meerkat mini PCs both running stock Unbuntu using Regolith for the desktop environment ( https://system76.com/desktops/meerkat ). They are stacked on top of each other on my desk and take up next to no space. I work from home (and have since 1999) and don't travel fo…

what do you find appealing about regolith? it seemed kinda heavy to me

The main appeal for me is it just works how I want it to work with little to no tweaking.

It won't. I'm using laptops since early 2000. Ability to take your computer to couch, bed, terrace, park, etc is irreplaceable. I do wonder why desktops still exist.

I use my desktop because I like a 24" screen and full size keyboard, plus I don't have to think about battery levels. My desktop is old enough that even a cheap laptop has similar computing power so that's not personally why I go to my desktop anymore.

Man I wish System76 or Framework or someone else could make hardware as nice as Apple. I just ordered an M2 Air which I will be primarily running Linux on. I'm replacing my Lenovo T480s (which was a great laptop) because I want _nice_ hardware. There are just so few options that even come close to competing with Apple.

There's plenty of good competition, just none of those options come with Linux—and as we saw with the Lenovo news yesterday, it's getting less friendly to install a FOSS OS.

I don't believe that there is any comparable hardware to the M* macbooks right now, linux or not.

Impressive it is for an "OS brand, yet it's just another relabelled Tongfang laptop, so people really need to blame not OEM, but people who keep buying from them instead of designing own hardware. Designing a laptop from scratch may be an adventure with a budget close to $200k-$300k, but there are tons, and tons of US brands who can pull this financially. Yet, even the "innovative" Framework laptop is mostly OEM work…

The Framework Laptop is entirely our own design and architecture, with no white-label or pre-existing ODM/OEM parts. The cost of developing a from scratch laptop like ours is closer to the mid seven figures.

I worked on some proprietary thing (not a laptop) and mid seven figures sounds about right for just the motherboard, case, etc.

Our thing was more custom than the framework, but mid seven figures sounds like a steal. Does that include making Linux be reliable on it? (5 engineers total on the EE/mechanical/industrial engineering and SW bringup teams * 4 year product lifespan is mid seven figures, just for salary. That doesn't include facilities, HW budget, stock, etc)

I've never used a framework, but I assume suspend resume is reliable, it can sleep for a week, the GPU works, sound card doesn't pop/crackle, etc, etc... That stuff is hard to get right over time as distros get updated, which is why the above team needs to stick around over time (hopefully while they make version N+1).

Well usually laptops don’t come from the OEM with Linux, so if you slap Ubuntu on there and the power management stinks, that’s on you.

Laptops with practical 10+ hours battery life usually come with Linux from the factory. Eg the google Pixelbook Go, which gets about 10-12 hours on a battery half as large as the one we are discussing. The System76 has mostly just thrown a gigantic battery at the problem.

I had this laptop, but ultimately replaced it with a 14” M1 Max. Some thoughts: - The screen is so much worse, in every way, than a MacBook. A “low resolution” (more like, not high dpi) matte screen vs the M1 screen, there is no comparison. When I first got this machine, my eyes would have to adjust to the screen, and it felt so blurry compared to my works retina Touch Bar Mac - PopOS is great! It is definitely one o…

I don't know who decided shinny screens are better but they aren't for me. Maybe they slightly reproduce color more accurately but most people are not graphic designers. Matt screens exist for a reason and can't just dismiss them as being inferior when they specifically solve a problem many have. Maybe they sell better in a store but so do touch screens in cars. Once you however want to use them you realize the mista…

I’m an artist and I am just as annoyed by reflections off the glass hiding what I’m doing as a programmer is. I have heard glossy screens took over largely because they look better in a store.

I was wondering how that got that battery life. I have an old system 76 (8th gen intel and nvidia) and while it’s quite speedy and can game, battery life isn’t great. The article hints at Linux now using intels new low power cores. Though I’m not sure exactly how. “Like Windows, Linux had to have some serious tinkering under the hood to prepare for the mix of Performance and Efficiency cores in Alder Lake chips. Howe…

There are lots of little tweaks that can make a huge difference in battery life. Since there's a lot more that was posted on the Framework community I use that as an example (but it can apply to any laptop model). OOTB, reports for idling was anywhere from 7-11W. With the Framework's 55Wh battery, that would mean that it would run down in 5-8h at complete idle (oof):

https://community.frame.work/t/issues-with-power-usage/12261

https://community.frame.work/t/nixos-power-consumption/6339

However, with some tuning, that can get down to as low as 2.5-3W:

https://community.frame.work/t/linux-battery-life-tuning/666...

https://community.frame.work/t/battery-life-impact-of-ram-me...

To summarize on the configuration options, the biggest gains are probably from powertop/tlp tunings, PSR, settings to get to C9/C10 on idle (PSR is a prereq for this), replacing PulseAudio w/ Pipewire, modifying the EPP values, and fstab options (noatime, relatime).

Of course, some of System76's gains could be spending some extra effort on their EC/BIOS tunings, or on the hardware itself (lots of ways to mess up or to get gains from the motherboard layout/components).

It's also worth noting that some SSDs like the Hynix P31 consume much less power than others, so hardware selection can play a part as well.
