Intel Management Engine is worse than secretly installing an SSL MitM and sending browsing data to an adware company run by former Israeli spies? Give me a break. Intel ME is worrisome. Lenovo's behavior was actually malicious. There's kind of a difference.

Lenovo Superfish was incompetently malicious. The ME allows Intel to competently pull off far more nefarious activities than blindly forwarding all browsing data and easily evade detection. Superfish was removable. The ME is far from it. There are alternatives to using Lenovo software or hardware, thus Superfish is even completely avoidable. The ME and its AMD equivalent are not. Both are worrisome. Backdoor-in-hardw…

ME is removable. Coreboot devs will often remove it for you if you meet them in real life and ask nicely. I've since got a setup for doing that myself so if you are ever around me in real life ask nicely and I'll remove it from your machine

This is short on details. So here are some more: since S0 ( active suspend) became more popular with windows 10, most manufacturers have decided to REMOVE THE CODE from the bios that allows S3 (suspend to ram). Worst case is they left the stubs pretending S3 is supported, so the computer goes to sleep - but never wakes up! Dell, I'm looking at you!! Workarounds come from redoing the S3 code, mostly in ACPI tables wit…

It's worrying how obscure and poor standards compliance modern hardware is starting to display. And we're talking about PCs. Let's not even discuss mobiles. In 2012 I bought a MacBook Air to run Linux. It's a great silent machine with all Intel hardware, except the pretty poor quality Broadcom wireless card. It boots with any vanilla kernel, and everything just works. Except for poor wireless range. What machine can…

I own Xiaomi laptop you mention for almost a year now (2016 model). It is overall a pretty fantastical laptop, especially for the price. But be aware, that some models (mine as well) have coil whine issue (1), so it may not be completely silent. Also, BIOS is very limited, you can disable security boot, choose boot device and that's pretty much it. However, Linux runs perfectly without jumping through any hoops.

I have everything working on my Lenovo T480 with Fedora Linux.

Thanks for those comments about the Xiaomi 12.

What do you find lacking in the BIOS? Don't you use EFI instead?

Have you tried setting `layout.css.devPixelsPerPx` to some multiplier like 1.5?

I find it's better to just zoom, FF seems to remember zoom levels by domain.

That's exactly the problem; I don't want to re-zoom every domain. I'd like consistent sizing everywhere, and devPixelsPerPx does that.

I bought the X1 6th gen, but ended up returning it for a refund due to poor Linux support. There is no excuse for breaking S3 suspend.

Did you find anything besides S3 that didn't work? I have the 6th gen X1 and once I patched in ACPI my ubuntu install has worked perfectly.

Touchpad was broken... Needed manual tweaking of configs. And even then it seemed I can have different speed for trackpad and touchpad.. I'm not impressed..

Also there is reports the CPU is underclocked on Linux..

And is the patch even a solution that is stable past the next kernel update?

Oh, each the mobile broadband didn't work either...

Obviously, fingerprint did work as usual... And I couldn't figure out if NFC works.

> ME is removable.

With proper hardware tooling and care, perhaps. (Side question: even for latest gen chips?)

For the vast majority of people, ME is not removable. For the AMD users, AMD's ME equivalent is not removable.

Didn't Lenovo used to get Thinkpads certified by Ubuntu and RH ? Did they give up on it ? That only leaves Dell as the other main vendor (not counting smaller niche players) that still gives a shit. Edit: Looks like they still do, just that certification doesn't mean shit. This is more RH and Canonical's fault than Lenovo's. What's the point of certifying something if you can add a note (as Canonical did) that suspen…

Ah, so it does meet their performance criteria after all. The elusive double negative.

I have zero issues with HiDPI on Ubuntu + xmonad set-ups. In particular, setting xrdb's Xft.dpi to a good value (e.g. 144, an "even" multiple of 96 for X1 Carbon) seems to work well. However, I mostly use my laptop for Chrome, emacs, and terminal, so YMMV. HiDPI screen is definitely worth it for your eyes.

Do you use external monitors that have different resolutions?

No. Unfortunately, I can't say good things about differing-display support in Linux. For example, even if DPI is matched but one of the monitors is rotated (my old setup), freetype anti-aliasing settings are still global and can't account for rotation :( This matters less with HiDPI, though.

Fortunately, Dell U2718Q's are relatively cheap and well-worth the upgrade :)
