Title:
Bluetooth keyboard has lag
Status in bluez package in Ubuntu:
Expired
Bug description:
For some days, I observe an annoying lag with my Logitech K380
keyboard and Ubuntu 20.04. After a couple of seconds not typing, new
keystrokes are registered only after 1–2 seconds lag. From there on,
I can type without lag, until the next typing pause.
I seems that the Bluetooth component switches Bluetooth in some sort of
hibernate after a couple of seconds of not typing, and then it needs 1–2
seconds to wake up again and process the keystrokes.
No keys are missing – they just arrive with a lag. Probably the keyboard
buffers them.
Important: If I listen to music with a Bluetooth headset, I can type
without *any* problems because the Bluetooth module remains awake due
to the music transmission.
The keyboard does not exhibit this issues at my Android tablet.
Furthermore, I am sometimes lucky can work with the keyboard without
any lag (and without music).
In the BIOS settings of the computer, I do not find anything
Bluetooth-related.
