I don't know what happened but sometime in the past week Something (a software update?) happened to our Debian 13 install and now whenever our laptop goes to sleep it does not wake up again, and this is just suffering

thank you to the person who suggested I do a kernel rollback, I should've tried that

I chose the old kernel 6.12.57 in the GRUB menu and now the laptop can go to sleep and resume as normal

/var/log/apt/history.log shows the 6.12.63 kernel was installed at "2026-01-16 04:38:59"

apparently kernel rollbacks are not a standard process, so here's what I did:

  • sudo apt-mark hold linux-image-6.12.57+deb13-amd64:amd64 to prevent old kernel being removed later
  • sudo grub-mkconfig to get a list of grub menu entries and submenus
  • sudo vim /etc/default/grub, changing GRUB_DEFAULT="Advanced options for Debian GNU/Linux>Debian GNU/Linux, with Linux 6.12.57+deb13-amd64" (yes, you have to write out the full name of the submenu and the menu item, with > between them…)
  • sudo update-grub to apply the changes to /etc/default/grub

ahhhh someone in the Debian support IRC channel helpfully pointed out that since this is a very new laptop, I should probably try the backported newer kernel version (sudo apt install linux-image-amd64/trixie-backports). now we're on 6.17.13 and it works much better!

not only does suspend work on this newer kernel version, but this laptop can finally β€œtruly” go to sleep; when a ThinkPad is sleeping, the LED in the logo and on the power button is supposed to gently pulse. that wasn't happening before!

@hikari If you are considering Linux, and you say you are worried about hardware support, everyone says "just throw it on an old ThinkPad! It'll work great!". The problem is that what no one tells you is that the "old" is load-bearing. If you want to run Linux it absolutely *must* be on an old ThinkPad. If you attempt to run it on a new ThinkPad, or *any* Lenovo product newer than 12 months at a minimum and 24 months preferably, you will be in fucking hell. I have experienced this myself twice.

@mcc I must say that until this suspend issue cropped up we were almost amazed that a brand new 2025 ThinkPad seemed to work flawlessly with stable Debian, but the fact this stable Debian release came out in 2025 is probably part of why

@apth @neurovagrant @mcc Framework are a particularly credible actor in that space, both because they actively try to support various Linux distros and because their laptops are uniquely configurable, so you can pick whichever generation of hardware works best. but I am obliged to mention some people are upset about their association with Omarchy and thus DHH, make of that what you will (I don't want to discuss it here, I'm just avoiding the inevitable reply)

@mcc @hikari idk if the intent of the message was that Linux only runs well on old hardware but that's kind of how it reads. I hope the intent was "only runs well on older lenovos".

Reading the OP and the follow on replies it seems this is in a thread of mostly(?) Debian users.

Linux runs great on a lot of modern hardware mostly AMD based. Preferably on hardware curated to run Linux. Framework, Dell and HPs Linux offerings, Penguin, System 76, KDEs slim thing etc. More choices every day.

@mcc @hikari I'm sorry to hear that. I've been running both an AMD laptop and desktop on Linux for the past 8 years through various machines from several vendors. Not without their occasional problems of course but then that's true of basically any hardware/software from time to time. I've sent back some Intel hardware for issues in both Windows and Linux. πŸ€·β€β™‚οΈ

@mcc @hikari
TLDR: I agree with "24 months preferably".

The 3 thinkpads (E14, X1, X1) in my household are about 4-6 years old.

At the start various minor things didn't work (not as bad as "fucking hell"*)
E.g. the volume and brightness buttons and leds wouldn't work until one sleep/wake cycle after powerup.

Eventually these problems went away with a software upgrade.

* Hell was our last HP laptop, where kernel of the time would permanently corrupt any mounted disk, even if only reading.

@mcc @hikari I dunno, I have Linux on my two desktops and very infrequently have problems. one has h/w from 2025 and runs on Bazzite, while my main machine has Fedora on it and works just fine. Fedora and derivatives have been the most stable for me - I used to have to reinstall everything every 1.5-2 years when I used Arch-based stuff and Debian-based often wouldn't work.

maybe give Fedora a try, but the most important thing is to use software that makes sense for your use cases and needs. if you don't need/want Linux, don't use it. I want to be as far away as possible from Windows, and if my music software functioned well on Linux I wouldn't have a Windows partition!
