Double keypress events with Librem 14?

Hardware
1

I was wondering for a bit now if there’s an issue with (my?) librem 14 keyboard, as I keep getting double keypresses, specifically with the DEL key. For a while, I thought that I was just fat fingering it, but after a few weeks of usage, this remains to be quite a nuisance.

So far, this seems to be consistent with the original PureOS installation, as well as using vanilla Debian (sid). I also recently flashed the new EC firmware to solve the INSERT key code issue, but that didn’t fix/improve the double keypress issues.

Below is an example capture using evtest, where i was hitting the DEL key at roughly 1 second intervals. You’ll see it’s fine the first few times, but then there´s two events in a quick succession.

As far as I can tell, this didn’t happen with any other keys either.
Maybe I really am just fat fingering this? Searching around in the forums didn’t show any other similar reports.

have you updated ec firmware?
Download

~$ wget https://source.puri.sm/firmware/releases/-/raw/master/tools/purism_ectool.gz
~$ gzip -d purism_ectool.gz
~$ chmod a+x purism_ectool
~$ sudo ./purism_ectool info

if your version is lower than 2021-08-03_05d9990
then you have update ec firmware.

No don’t do that.
Take a look here https://puri.sm/librem-ec

sudo ./purism_ectool flash_backup ec-2021-08-03_05d9990.rom

Still having the same issues so far.

For what’s worth, from my experience, the double key-press issues do not seem to be related only to the Del key, as I had the same happen with other keys as well since the first report. It does seem to happen less often, though.
