Frankly, I got a Lenovo T14 Gen 3, 12th gen Intel.

It's the worst laptop I've had in a decade.

They spent 6 months fixing an issue where two internal DP ports where visible to the driver which caused the kernel to not survive a suspend. The issue is with the Tigerlake reference design, and a lot of companies will need to push firmware updates to get things sorted out.

This is the upstream driver issue: https://gitlab.freedesktop.org/drm/intel/-/issues/5531#note_...

EDIT:

I realized I'm typing this on the 11th gen Framework I own. While the Lenovo laptop is somewhere behind my couch, I think.

This is actually an important comment, because it is about the same CPU in a different machine, which could help isolate the problem. The more interesting question is whether there's a general problem with Intel's 12th gen chips, because that will affect far more people than anything Framework does.

12th gen is just terrible in general. My Dell XPS 15 is a real turd. My old 7th gen intel is better. And my AMD one destorys it.

I've a laptop with a 12th gen and a nvidia gpu, works like a charm despite the configuration.

I don't think it has to do with intel.

This. I have two T480 laptops that run Linux extremely well, but I have no intention of upgrading until Intel/Microsoft sort out their bullshit "modern standby" issues. Just let me fucking suspend.

Do contemporary/current-gen AMD laptops do "modern standby" or "traditional standby"?

I don't know about the very latest generation or about other OEMs, but my work laptop is a previous-generation (Ryzen 5xxx) AMD-equipped ThinkPad. It did "modern standby" by default but that can be flipped to S3 sleep in the BIOS settings.

My Ryzen 4000 laptop (Tong Fang PF5NU1G) had regular S3 suspend that worked reliably, but sadly it seems many Ryzen 5000+ models seem to have it stripped out (these can sometimes be added back in by loading patched ACPI tables [1]).

Oh, and for a bunch of Ryzen 6000 laptops it's been even more dire since they've also had s2idle issues that have only just gotten patched [2].

I used company-provided dell/lenovo laptops for more than a decade. This isn't specific to the 12th gen intel version.

Intel GPU issues on linux were/[are?] omnipresent. Aside from a few lucky generations, for me it always took 1yr after obtaining a new laptop to resolve most of the issues. We go from random suspend issues related to the display not coming up, to massive framebuffer corruption when moving the hw cursor around making the display unusable without workarounds. The biggest issues usually get resolved within the first 2-6 months, but still it's extremely annoying for the absolutely most popular gpu in linux territory, and often quoted as "the best supported gpu" from a driver perspective too. I know intel employs a few full-time employees for this. Far too little apparently for a company of this size. First to get KMS, yet I couldn't ever get opencl working without their own custom/broken driver which is not even part of mesa, not to mention the amount of software that downrights blacklists intel drivers everywhere.

I'm on a T14 amd now. Can't say it's all rosey (it isn't), but I had next to zero issues on the GPU front with vega straight after getting it.

We must live in parallel universes. T15 gen 2 here, works phenomenally on ubuntu 20.04.

Same here, but I chose the AMD T14. Flawless.

You misunderstand. All the Lenovo laptops I've had are flawless. The issue is the 12th gen Intel board which you can select on some models.
