2K is only a few more pixels than 1920 x 1080 ? I find the sweet spot minimum for my 27" desktop monitors to be 1440P. Anything that and above looks great.

> 2K is only a few more pixels than 1920 x 1080 ? Given you said you use 1440p monitors yourself, I think there is a misunderstanding somewhere here, because 2K is just a less commonly used term for 1440p. And 1440p is definitely a bit more than just "a few more pixels" compared to 1080p (iirc around 78% more).

Since when is 2K used to mean 1440p? 1440p 16:9 gives a horizontal resolution of 2560px. That's more than what is considered 2K, which is generally either 1920px or 2048px.

No idea, since I haven't seen the term 2K being used much at all in the wild. So I simply googled that term, and it seems to be overwhelmingly used to refer to 2560x1440.

> You just have to set it up to fully power down the GPU. Can you please tell us a bit more? I have a NVidia + Intel GPU. I was thinking about using the NVidia for KVM (the NVidia would be powered down when not using KVM), and the Intel for native linux display with Pop or Ubuntu 22 LTS as another attempt to use Wayland (since I read NVidia GPUs can cause many issues)

On modern Linux systems the way to do it is using PRIME render offload. That way, the Intel (or AMD in my case) integrated GPU will be used normally, with the Nvidia GPU fully powered down (you need a new enough card for this). Then, when you need it, you can use a command or environment variable or graphical launcher to signal to use the dGPU for offloading. The GPU will then power on and render to a virtual display…

> Display is configurable from the base version 15.6” FHD (1920 x 1080) IPS up to 15.6” 4K (3840 x 2160) OLED with Dolby Vision HDR.

> I had to choose the 15.6” FHD (1920x1080) Dolby Vision HDR screen, because 4K options are not supported on the integrated GPU. It’s a HDR400 WVA IPS display panel with 16:9 aspect ratio, 800:1 contrast ratio and 72% NTSC color gamut.

Sigh. There's no way I would want an NVidia card in any laptop, especially not a linux one. Why must companies do stupid configuration tie ins like this? At least there's a workaround.

Related: If you want a Dell laptop with Linux preinstalled, they probably won't let you max out the RAM and/or CPU.

This is one of the primary reasons I can't even consider moving away from an M1 Mac. I used to love ThinkPads but not being able to use the machine for 10+ hours without charger is a dealbreaker in 2022.

My pinebook pro beats those numbers, and it was $200.

4 hours intensive use would be a more of a deal breaker for me than the combined flaws of the pinebook pro, so I'd pay up to $200 for a laptop that only got 4 hours.

Yeah, I am getting there; I just like working under Linux more and mac OS X does a bit, but nothing is like Linux with i3 for me; it is so much more productive (for me).

i3 runs fine on macOS

Link?

I don't think something is usable without GPU acceleration.

Some acceleration for sure is necessary, though things like video acceleration (that belong in the set "polished GPU drivers") are quite secondary. Linux is a good example of that, accelerated video decode is still quite rare and finicky.

> a 2014 MBP Great example. macOS Monterey minimum requirements: "MacBook Pro: Early 2015 and newer" So Apple forces that device to be e-trash, regardless of your desires.

While I agree to most of the glued/soldered/planned obsolescence criticisms related to applethings I do feel the need to point out those "obsolete" macthings tend to run Linux just fine. I should know, writing this on a 'late 2009 27" iMac' which I got for free due to its video card being broken (which it is no longer, 8 minutes in the oven at 195°C is all it takes) running Debian. While it is also possible to get mo…

Uhh, nope. NVidia and Broadcom all over.

my TI 86 lasts for days on a single set of AA batteries, but you don't find me comparing it to my dell workstation, now do I?
