I’ve started having this issue where the “c” key and sometimes “e” key don’t register when pressed. If I open a text editor and slowly press “c” over and over, putting pressure on different parts of the key, I can see that there are just some areas where pressure doesn’t register a key press (unless I press really hard). The “e” key is much more intermittent, so I can’t draw much in the way of conclusions here.
I’m tempted to try to remove the key caps to see if something has gotten under them, but I seem to recall (but can’t find it now) a forum post here somewhere suggesting that the key caps aren’t meant to be removed, and doing so can damage them.
I’m on Debian testing (trixie), though this doesn’t feel like a software issue. I see this on a 13th-gen Intel board, though I also saw the problem on 12th-gen. I’ve tried reseating the input connector, but that didn’t help.
