It's a shame that this didn't end up going anywhere. When Qualcomm was doing their press stuff prior to the Snapdragon X launch, they said that they'd be putting equal effort into supporting both Windows and Linux. If anyone here is running Linux on a Snapdragon X laptop, I'd be curious to know what the experience is like today.
I will say that Intel has kind of made the original X Elite chips irrelevant with their Lunar Lake chips. They have similar performance/battery life, and run cool (so you can use the laptop on your lap or in bed without it overheating), but have full Linux support today and you don't have to deal with x86 emulation. If anyone needs a thin & light Linux laptop today, they're probably your best option. Personally, I get 10-14 hours of real usage (not manufacturer "offline video playback with the brightness turned all the way down" numbers) on my Vivobook S14 running Fedora KDE. In the future, it'll be interesting to see how Intel's upcoming Panther Lake chips compare to Snapdragon X2.

Depends why the Snapdragon chips were relevant in the first place! I got an ARM laptop for work so that I can locally build things for ARM that we want to be able to deploy to ARM servers.
I'm typing this from a snapdragon x elite HP. It's fine really but my use is fairly basic. I only use it to watch movies, read, browse, and draft word and excel, some light coding.
No gaming - and I came in knowing full well that a lot of the mainstream programs don't play well with snapdragon.
What has amazed me the most is the battery life and the seemingly no real lag or micro-stuttering that you get in some other laptops.
So, in all, fine for light use. For anything serious, use a desktop.
Better efficiency of X86 mobiles CPUs does negate much of the advantage of ARM laptops. It's just not worth the trouble of going through a major software transition.
One thing that I find suspicious is the large delta in single thread score between ARM and X86 currently. The real world performance does not suggest that big of a difference in actual use. The benchmarks suggest a 25% performance delta but in actual use the delta seems to be less than 10%.
Of course Apple Silicon has the efficiency crown very much locked down
Since they have become a marketing target the benchmarks have become much less useful.
I was incredibly excited when they announced the chip alongside all kinds of promises regarding Linux support, so I pre-ordered a laptop with the intention of installing Linux later on. When reports came out that single core performance could not even match an old iPhone, alongside WSL troubles and disappointing battery life, I sent it back on arrival.
Instead I paid the premium for a nicely specced Macbook Pro, which is honestly everything I wanted, safe for Linux support. At least it's proper Unix, so I don't notice much difference in my terminal.
It's ACPI - most laptops ship with half-broken ACPI tables, and provide support for tunables through windows drivers. It's convenient for laptop manufacturers, because Microsoft makes it very easy to update drivers via windows update, and small issues with sleep, performance, etc. can be mostly patched through a driver update.
Linux OTOH can only use the information it has from ACPI to accomplish things like CPU power states, etc. So you end up with issues like "the fans stop working after my laptop wakes from sleep" because of a broken ACPI implementation.
There are a couple of laptops with excellent battery life under linux though, and if you can find a lunar lake laptop with iGPU and IPS screen, you can idle around 3-4W and easily get 12+ hours of battery.
In addition to the other comments, its worth noting macOS started adding developer documentation around energy efficiency, quality of service prioritization, etc. (along with support within its OS) around 2015-2016 when the first fanless usb-c macbook came out: https://developer.apple.com/library/archive/documentation/Pe...
Think I'm arguing its both things where the OS itself can optimize things for battery life along with instilling awareness and API support for it so developers can consider it too.
Newer laptops come with extra power peripherals and sensors. Some of them are in ACPI tables, some are not. Most of them are proprietary ASICs (or custom chips, nuvoton produces quite a bit of those). Linux kernel or the userspace has poor support for those. Kernel PCIe drivers require some tuning. USB stack is kind of shaky and power management features are often turned off since they get unstable as hell.
If you have a dGPU, Linux implementation of the power management or offloading actually consumes more power than Windows due to bad architectural design. Here is a talk from XDC2025 that plans to fix some of the issues: https://indico.freedesktop.org/event/10/contributions/425/
Desktop usage is a third class citizen under Linux (servers first, embedded a distant second). Phones have good battery life since SoC and ODM engineers spend months to tune them and they have first party proprietary drivers. None of the laptop ODMs do such work to support Linux. Even their Windows tooling is arcane.
Unless the users get drivers all the minute PMICs and sensors, you'll never get the battery life you can get from a clean Windows install with all the drivers. MS and especially OEMs shoot themselves in the foot by filling the base OS with so much bloat that Linux actually ends up looking better compared to stock OEM installs.
A lot of people say that lightweight desktops/distros help. Probably GNOME/KDE unnecessarily use your SSD, network, GPU and other resources even when you are idle, compared to using a minimal WM and only starting the daemons you actually need.
I personally never tested it, and I can't find definite benchmarks that confirm and measure the waste.
While each of the comments here describe individual failings, on a well supported laptop it is possible to get better power efficiency than windows if your willing to spend the time manually tuning linux, the powertop/etc suggestions are fine, but fundamentally the reason some of the 'lighter' DE's save so much power is that there is a lot of 'slop' in the default KDE/GNOME and application set. You have random things waking up to regularly and polling stuff which pulls the cores out of deep sleep states. And then there are all the kernel issues with being unable to identify and prioritize/schedule for a desktop. Ex: the only thing that should be given free reign is an active forground application, grouping and suppressing background applications, running them on little cores at slow rates if they have work to do/etc. All that is a huge part of why macos does so well vs linux on the same hardware.
The comment about ACPI being the problem is slightly off base, since its a huge part of the solution to good power management on modern hardware. There isn't another specification that allows the kind of background fine grained power tuning of random busses/devices/etc by tiny management cores who's entire purpose is monitoring activity and making adjustments required of modern machines. If one goes the DT route as QC has done here, each machine needs a huge pile of custom mailbox interface drivers upstreamed into the kernel customized for every device and hardware update/change. They get away with this in the android space because each device is literally a customized OS and they don't have the upstream turnaround problem because they don't upstream any of it, but that won't scale for general purpose compute as the parent article talks about.
I mean I feel like once one of the ARM chipmakers can lend a hand on the software side it should be a landslide.
Google and Samsung managed to make very successful Chromebooks together, but IIRC there was a bunch of back and forth to make the whole thing boot quickly and sip battery power.
What’s the primary need for ARM? Is it because Apple silicon showed a big breakthrough in performance to power with reduced instruction set? While it’s amazing on paper I barely notice a difference on my day to day use between an Intel Ultra and a M2 in performance. Battery life is where they are miles apart.
I fully expected this. I really wanted to get the Snapdragon X Elite Ideacentre just because I wanted an ARM target to run stuff on and if I'm being honest the Mac Minis are way better price/performance with support. Apple Silicon is far faster than any other ARM processor (Ampere, Qualcomm, anything else) that's easily available with good Linux support.
I am so grateful to the Asahi Linux guys who made this whole thing work. What a tour de force! One day, we'll get the M4 Mac Mini on Asahi and that will be far superior to this Snapdragon X Elite anyway.
I remember working on a Qualcomm dev board over a decade ago and they had just the worst documentation. The hardware wouldn't even respond correctly to what you told it to do. I don't know if that's standard but without the large amount of desire there is to run Linux on Apple Silicon I didn't really anticipate support approaching what Asahi has on M1/M2.
This feels like BAU for PC vendors - you test out a product on a new combination of hardware, and it isn't mature/stable/ready for production, so you kick it down the road to develop later - this is especially true for Linux, where a LOT of the work would be done outside of your organisation.
Hardware companies generally start working on a laptop before a SOC is released, not after. They also need to secure manufacturer support, in this case Qualcomm to be able to deliver in time.
We can nerd it out about Linux this an S3 sleep that. How much money does the community need to raise all in, for that notebook to happen. Where's the GoFundMeAngelList platform that's a cult where I can pledge $10,000 to get this laptop of my dreams? Or are we all too busy shitposting?
I wonder if Mediatek will try its hand as laptop oriented SoC now that their flagship mobile SoC are competitive again and Google is merging Android and Chrome OS.
Generally, they are far nicer than Qualcomm when it comes to supporting standard technology.
Somewhat tangent: x86-based laptops of this brand (it is new to me, I never meet Tuxedo Computers before) looks attractive, but there is no information about their screens main property: are they glossy or matt?
My wife is very sensitive to glossy screens and we have big problems to find new laptop for her, as most good ones are glossy now.
> We will continue to monitor developments and evaluate the X2E at the appropriate time for its Linux suitability. If it meets expectations and we can reuse a significant portion of our work on the X1E, we may resume development. How much of our groundwork can be transferred to the X2E can only be assessed after a detailed evaluation of the chip.
Apparently the Windows exclusivity period has ended, so Google will support Android and ChromeOS on Qualcomm X2-based devices in 2026, https://news.ycombinator.com/item?id=45368167
Was to be expected. Qualcomm sucks very much to support open platforms.
I was disappointed to see that no more good linux compatible XPS was available anymore because they are now based on the last snapdragon for bullshit windows "ai" reasons.
Qualcomm doesn't bother to upstream most of their SoCs. They maintain a fork of a specific Linux kernel version for a while and when they stop updating it or new version of Android requires newer kernel then updates for all devices based on that SoC end.
They have little experience producing code that is high enough quality it would be accepted into Linux kernel. They have even less experience maintaining it for an extended period of time.
I wonder what made it so hard? I thought that Snapdragon was already providing the Linux drivers? Anyone knows? Maybe those were not OpenSource?
My guess is that it's all the same as in Linux phones that they have large blobs of drivers given by the board producer but not being open, but then... Maybe we should invest time in microkernels? Maybe Linux is a dead end because of the monolithic architecture? Because I doubt big companies will change...

Only RISC-V is worth switching to.

Google has already built Chromebooks (which are Linux based) on them, so presumably the necessary drivers exist.
Outside of laptops, NVidia sells its Jetson Devkits and DGX workstations which run Linux and are pretty fast and ARM based.
And System76 also sells a high powered (and $$$) Linux workstation based on an NVidia ARM chipset
So at least for some ARM SOCs, performance issues have largely been solved.
They have little experience producing code that is high enough quality it would be accepted into Linux kernel. They have even less experience maintaining it for an extended period of time.
My guess is that it's all the same as in Linux phones that they have large blobs of drivers given by the board producer but not being open, but then... Maybe we should invest time in microkernels?
