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.

No idea what the solution is, but this is funny af

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.

Don't bother, that's normal /sssssssssssssssssssssssssssssss

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.

@pukeko that was a fun read 🫠 strange behaviour.. Was gonna say about a dirty keyboard, but it's clearly more than that. Hope you get sorted friend 🙃

Anything interesting happening in the kernel logs? Sudo dmesg.

S-tui would give you some idea if there's a thermal issue.

It is very, very odd that you have the same thing going on in your laptop and desktop. Has the thermal conductance of air (or some other related physical property) changed locally? Have you replaced the thermal paste on both devices with asbestos exhaust pipe putty? I keed, I keed.

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.

My only guess is that maybe your input device is disconnecting, then reconnecting.

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

I never sorted out what the answer was but I'm almost certain it was a gnome issue, possibly a conflict. I did manage to completely hose my system through troubleshooting, but, hey, I just grabbed an earlier version of my nix config, typed one command, and was back up and running in an earlier state. NixOS is weird and troublesome to learn but goodness it's useful.

Have you tried turning off the repeat keys function? https://help.gnome.org/users/gnome-help/stable/keyboard-repeat-keys.html.en

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

Hehe

Had something similar happen to me a couple of days ago setting up a new desktop, micro freeze and an input being repeated. Turned out the ram was a little bit over the stable clock. Reverted the typo on memory clock and all's fine now. Don't know if you control that in you laptop tho
