[Bug 175743] Re: Bluetooth Mouse looses connection after some time of inactivity
I think Robert Lange (rcl24)'s speculation on 2008-05-21 is true. I have
the same issus with my apple wireless keyboard but not the accompanying
apple wireless mouse. I must manually disconnect the keyboard in the
system (by using my mouse) and then touch it. If I touch the keyboard
first, the first single key input will be recieved correctly by the
system whereas the following key input are ignored - maybe the rejection
of the keyboard's reconnecting request has happened immediately after
the first key press.

(Note: This is a direct copy of my bug KDE bug report at
I have two Logitech Bluetooth Mice: One MX900 and one MX1000 on an HP Laptop with integrated Broadcom Bluetooth connectivity. I can pair both easily using the tray applet, and they both work flawlessly initially.
However, after some time of inactivity (Not using one mouse for some time, Going away from the System, etc) the connection is lost and won't be re-established, even after moving the mouse constantly.
I go to Configuration -> Input Devices and both Mice are listed. The
mouse that hasn't been used for some time (don't know the exact
amount), doesn't show the yellow star in front of its name any more
(The other one in use still has the yellow star). Selecting the
inactive mouse and pressing "Connect" doesn't help. I can only re-
connect if I press the "Discoverable" Button on the mouse and then
press "Connect" in the dialog.
The effect is the same with both mice. The disconnection happens
always after mouse some inactivity time. This bug makes Bluettooth
mice operation under KDE currently not usable at all.
Bug Impact: Currently all users of bluetooth input devices will be unable to use their input device after leaving it idle for an extended period of time. The only workaround is to unplug and plug back in the device again.
Addressing: Upstream has a patch in CVS head that works around the
1) Install Ubuntu on a system with a supported bluetooth controller.
2) Pair a BT mouse or keyboard with the computer. Verify that it works
3) Disable any suspend when idle options on the computer
4) Leave the computer idle for 30+ minutes.
5) Verify that the mouse and/or keyboard have stopped working.
