#256831 — bounncy keyboard

My keybboard is getting bouncy agaain.

I can swap it out under warranty but I wondered if there were some 
setting in Debian 11 to ignore the same character arriving too soon 
after the previous one?

It should also not worry if two different characters arrive closely spaced.

It's claimed that xkbset handles this, though I've not tried it.

Cheers,
David.

I use:

1.  A KUL 87-ES USB keyboard that came with a matching USB to PS/2 adapter.

2.  A Microsoft Wheel Mouse Optical USB and PS/2 Compatible that came 
with a matching USB to PS/2 adapter.

3.  An IOGEAR GCS78 8 port PS/2 keyboard VGA video PS/2 mouse switch.

4.  Dual PS/2 and single VGA cables that came with the switch.

5.  IOGEAR GUC100KM and GUC10KM PS/2 to USB keyboard and mouse adapters.

6.  USB 2.0 ports on various computers.


I have been experiencing semi-random keyboard problems for years -- lost 
keystrokes and stuck keys.  Things got really bad in the past few 
months, after ordering another new GUC10KM adapter and putting it into 
service.  After a week of testing and discussions with IOGEAR technical 
support, I narrowed the problem down to the newer revision GUC10KM 
adapters (purple and green PS/2 connector inserts).  After replacing 
them with 10+ year old revision GUC10KM adapters (gray PS/2 connector 
inserts), the keyboard problems went away.  I have ordered more old 
GUC10KM adapters on eBay.


I was having bad mouse issues a few years ago.  The problem was a bad 
mouse.  I replaced the mouse and the problems went away.


Do not overlook potential hardware problems.  It is wise to have a 
decent supply of spare parts for A/B testing.


I have started keeping written records of my GUC10KM adapters by serial 
number.

  your desktop may have some adjustment capabilities that
might help.

  i was having some keyboard issues a few weeks ago but it
turned out to be the connection was not good so i put a
large rubber band on the two ends of the respective USB
cables to tie them together more tightly and that solved
the issue.  i use a rather long cable.

In XFCE : Applications -> Settings -> Keyboard
You can test the repeat delay/speed in the test area at the bottom, or 
completely disable key repeat.
Other DEs should have the same settings.
For consoles/vt, no idea.
