[Launchpad Bug Tracker <1239204@xxxxxxxxxxxxxxxxxx>]

You have been subscribed to a public bug:

I have a Logitech K810 Bluetooth keyboard. The trouble is as follows:
every now and then a pressed key causes Ubuntu to think that the key is
being held; for instance, when I try to type “google”, I may get
something like “ggggggggggggooglllllllllllleeeeee”. It happens to any
key including arrows and Backspace; sometimes multiple times over typing
a single word, sometimes I can type for five or ten minutes without
experiencing the bug.

The laptop’s original keyboard is unaffected.

It is not a hardware bug, as a) the keyboard works fine when connected
to an iPad, and b) the keyboard worked fine on 13.04.

The bug isn’t limited to any particular program and is also present
while typing in terminal (the Ctrl-F1 one) or at login.
