I have this issue with my keyboard.

My connection:

WASM CODE V3 keyboard -> UGreen USB 3.0 switch -> desktop computer

I don't know which device(s) are at fault but when I get off my (non-Ikea) chair[0], my keyboard sometimes stops working. It's easy to resolve by double-tapping the 'switch input' button on the USB switch, although sometimes the keyboard doesn't work until I click my mouse (or maybe vice versa). Anyway, I've gotten used to it and don't have any motivation to diagnose the issue further.

I once had the problem that running make with too many parallel jobs (-j) would change my keyboard layout.

The machine was some laptop mainboard glued to the backside of my monitor, and the USB socket came out at the top of the mainboard. On its way down, the USB cable for the keyboard passed across the whole mainboard. On high load, the mainboard created enough interference to cause the connection to reset, re-hotplugging my keyboard, so the previous setxkbmap call was not effective anymore and i was back to the standard US qwerty layout.

Had the same issue a while back, had a hell of a time figuring out why one of my screens would flicker or shut off momentarily whenever my girlfriend sat down at her desk (which is next to mine). Even initially figuring out that it was the act of her sitting down that caused it took some time, with a lot of jokes about her telepathically messing with my setup in the meantime. Turns out that the gas piston in her chai…

There is a noise filter that you can clip onto the power line or other cables to help prevent radio transmissions from going into the line or other sources of noise. Maybe one of the cables is acting as an antenna. https://www.amazon.com/VSKEY-Anti-interference-Telephones-Eq...

With 300+ cables in my setup for audio, that's not what I want to read.

Remotely related, my screen makes a noise, somewhere between static and a whine, while displaying certain text files. Minimizing or closing the editor stops the noise, getting the text back on display restores the noise. I suppose it's some sort of resonance phenomenon.

Perhaps a silly question, but does turning it off and back on again also resolve the problem?

I can occasionally hear such noises from monitors, and have always thought it was some kind of interaction with the phase of the AC power and some kind of internal physics of the monitor. Generally, turning it off and back on again fixes it for me.

Wow, so I wasn't crazy - exactly the same thing used to happen to me when I got up from my Markus and the screen would turn off for a second. My hypothesis was a loose cable which I bumped slightly, but not touching the table when getting up didn't work. Not sure why, but it eventually went away.
