I've had a near continuos clone of this problem with the only wireless 
keyboard I'll allow in the same room as a swarf throwing metal carving 
machine. A logitech K-360.  The problem can be solved on an rpi3 by 
calling up raspi-config as soon as its rebooted, and resetting the 
keyboard repeat.  Most versions of linux gui's have a similar function 
if you can find it.  Big IF.

So IMO its something in the boot that does not properly set this, or 
maybe its set before the keyboard is found. Wireless keyboards (bt 
stuffs) and mice are way late found according to dmesg.  Once set, its 
good to the next power bump that reboots it.

Key shape (square sided keys) is what makes the logitech k-360 king in 
the shop, 99% of all keyboards have a straight walled mask around the 
tapered keytop. A bit of swarf falls into that tapered gap, follows the 
key down, and then wedges it in the down position. If that stuck key is 
in charge of moving the machine, all hell breaks loose because you 
didn't stop it by removing your finger. This is the major reason the 
high priced controls are all touch screen.

Thank you! that solves it.  It was indeed the change from 2 → 3 what I did.


Interesting. What is the computer/motherboard/firmware make/model ?
The one reported in a forum was an Aorus x470 Ultra Gaming motherboard.


Close! B450 AORUS M :-)


There must be something wrong is Aorus firmwares.

Also, it was later reported that replacing the keyboard with a different 
model solved the issue. The original keyboard was Logitech G510.

That is right, but GRUB also is capable of changing the video resolution
and some other settings, so I thought that could be another sensible
configuration parameter.  After all, is a complete OS itself, if I am not
mistaken.

GRUB's.


You won't find anything useful there. By default, the keyboard in GRUB 
is managed by the BIOS/UEFI firmware. The firmware setup may have 
typematic delay and rate settings.



I read a report about a similar issue in a Debian-related forum. IIRC,
a workaround was to connect the keyboard to a USB port of different

GRUB key repeat too fast

[Alberto Luaces]

Hello,

I have switched to a new computer an existing Debian installation.

At boot time, at the GRUB menu, each key press is repeated very fast, as
if the key repeat delay were close to zero: I can only select either the
first or the last option, since pressing the arrow keys go all the way
up or down.

If, for example, I press 'e' to edit an entry, it is shown, but also
almost 70 'e' characters are typed as well in the editing box.

I have searched for a key repeat delay in the manual, but I found
nothing.

Does this ring a bell for someone?

Thanks.
