You’re going to see some typing errors in this post, and thaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaat is intentioooooooooooooooooooooooooooooooooooooooooooooooooooooooooonal. It’s going to make the post unpleeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeasant to read, but I assure you it’s more unpleasant to type.
The issue: Every 5-10 seconds or so, my laptop has recently started pausing, with one symptom being repetition of any key I happen to be typing at that moment, whether a letter, deletion, or something else. I haven’t changed anything, and something very similar seems to be happening on mmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmy Fedora-based desktop.
I have tried thhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhe usual troubleshooting steps, such as watchinggggggggggggggggggggggggggggggggggggggggggggggggggggggggggg my processes, disabling gnome extensions, and I cannot pin down the cause.
(1) Annnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnyone seen anything like this?
(2) Any suggestions for troubleshooting?
The laptop is more than powerrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrful enough, a Gen 8 X1 Carbon. OS and apps are up to date. I assume an OS, gnome, or applicationnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnn update has broken something, but I cannot for the life of me pinnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnn down where the issue is occurring.
EDIT:
Adding system specs –
Intel® Core™ i7-10610U 16GB Intel® UHD Graphics Gnome/Wayland NixOS 23.11 kernel 6.1.57
EDIT 2:
Well, it appears to be gnome. Switched to KDE and everything is perfectly fine. I don’t like KDE (but I fully respect others’ preferences, just … to avoid unpleasantness). I’m going to do some digging around to see if gnome is conflicting with something in NixOS land.

I hope I don’t get flayed for saying this, but I actually had this problem on Windows once, and it turned out to be thermal throttling of the CPU. I was going from 4+ghz to around 200mhz and then it would shoot back to normal. Just needed a thorough cleaning of the fans and ducting.
Thought it was worth mentioning on the off chance it might help someone.
I have no idea how to fix something like this, but what would I do is try to isolate the problem. Boot live iso with another Linux and see if that happens again. If it does, I would try live windows iso to see if it can be because of Linux kernel or drivers. I it happens even on windows, it’s probably a hardware thing.
This is your best bet op. You can’t figure out the issue if you don’t know where the problem is coming from
I would try in the terminal (Ctrl+Alt+F3 or F1 or F2 depending on the distro), and then a live iso, then a live version of Windows or the Windows installer.
Don’t bother, that’s normal /sssssssssssssssssssssssssssssss
LOL.
Or, rather, LOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOL
the least you can do is provide the basics - AMD/Intel, GPU, wayland/x11, os and kernel version, I’m not looking up what an 8th gen x1 runs on.
as to your question, seen similar with ryzens freezing for seconds intermittently on older kernels.
You’re right, but it’s pretty horrendous typing in this environment so it slipped my mind.
Intel® Core™ i7-10610U 16GB Intel® UHD Graphics Gnome/Wayland NixOS 23.11 kernel 6.1.57
No idea what the solution is, but this is funny af
I have been entertaining myself by reading this post out loud. It sounds like I’m having a stroke over and over.
Can you boot into an old generation and see if that fixes the issue? If it doesn’t maybe check if you’ve updated firmware recently
Have you tried turning off the repeat keys function? https://help.gnome.org/users/gnome-help/stable/keyboard-repeat-keys.html.en
The repeating is a symptom, and the system pause/stutter/whatever is still happening regardless. I thought about it just as a sanity play, but I’d rather fix the underlying issue.
I actually might be having a similar issue on one of my servers, every 5 to 10 seconds the hypervisor will just freeze for less than a second, and it doesn’t repeat characters but it still makes typing in SSH super annoying. I did find using irqstat that during that time, interrupts from the ahci kernel module would spike into the 50,000s, so I have a feeling it’s to do with that, but I haven’t really figured it out yet, since it somehow doesn’t actually seem to affect my VMs.
Although it probably isn’t related considering switching to KDE fixed it for you, and I haven’t got display stuff installed.
Is your keyboard connected using USB or Bluetooth? I had similar problem in the past and it turned out that was an issue with my Bluetooth dongle
Integrated laptop keyboard (so I assume USB under the hood?)
My only guess is that maybe your input device is disconnecting, then reconnecting.
Hehe
