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 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.
