1 month ago Okay I just tested with Windows 10 and a USB version of Ubuntu 24.04 LTS. The bug was present in Ubuntu but not in Windows. If there's any other Operating systems worth testing let me know. Is there a more "base" level OS I should be looking at? I should probably try to report the bug at the lowest level possible, yeah?

1 month ago Will do.
I just tried it with Arch but I couldn't figure out how to get past the initial setup screen. The bug doesn't exist on that initial terminal screen in set-up. That prompted me to try typing on that temporary CLI login that shows up when starting Mint from a full power off and the bug does not exist there.
So recap so far:
Mint - Yes Mint Temp CLI Login - No Ubuntu - Yes Arch - Maybe not? Windows - No

1 month ago Most likely a kernel issue. What's the make and model of the keyboard?

Try launching the Driver Manager (in the System Settings).

1 month ago Are you sure this isn't a hardware issue? Can you try plugging in another keyboard? I used to have a Logitech keyboard that had an issue similar to this and it didn't happen all the time.

Keyboard: 01AX120 (the integrated keyboard on the laptop)
I don't believe this is a hardware issue because the button behaves as expected in windows and in the Arch install command line interface. Plus the evtest output doesn't spit out the following over and over like it does if you hold it down:
Event: time 1715974930.271262, type 4 (EV_MSC), code 4 (MSC_SCAN), value 0e
Event: time 1715974930.271262, type 1 (EV_KEY), code 14 (KEY_BACKSPACE), value 0
Event: time 1715974930.271262, -------------- SYN_REPORT ------------I checked Driver Manager but for some reason I'm only seeing the GPU driver options and nothing else. However, I figured out how to get the terminal to spit out a list of all the drivers. The problem being I don't know which one is the one I'm supposed to be interested in, so I don't know which one to ask the terminal to give me details about.
Here's the list, which ones should I get more info on?

1 month ago Okay, I'm now on kernel: 6.5.0-35-generic
The bug persists with the same behavior and the same output from evtest when I test the keyboard.

1 month ago From what I've read, the evtest output is telling us this is a kernel issue? Who is in charge of the kernel? I'm perfectly happy to work with them to get to the bottom of this.

https://unix.stackexchange.com/questions/494698/thinkpad-second-sticky-backspace-key
Although that still doesn't fully explain why it works properly before the kernel loads. I don't really know when the kernel loads or even what it takes over from, I'm just guessing that something else is in control for those CLI parts where there's no bug.

Bug description
A single press on the numberpad backspace key causes the computer to think the key is held down. The continuous backspace only stops when another key is pressed. From playing around with a CLI program called evtest, it seems the computer sets the key value to 1 on press but doesn't set it to 0 on release. For other keys, a return to 0 is the normal behavior. Evtest will repeatedly report a value of 2 if a key is pressed and held, and it does this correctly with the numberpad backspace. However, a single press on the numberpad backspace and then a single press with the regular backspace shows a value of 2 for the second key even though the first was not held.
The standard backspace key behaves as normal.
Steps to reproduce
Open a text file and populate it with text
Press the numberpad backspace
watch the cursor eat the text without your help
press any other key to stop the madness
Expected behavior
Should behave the same as the ordinary backspace
Additional information
Output from evtest on the following button combination:
Down Backspace Numberpad Backspace Numberpad Backspace Backspace Backspace Numberpad Backspace Down Numberpad Backspace Down Backspace Down Backspace
