Description dukat 2007-12-12 00:27:50 UTC

Version:            (using KDE KDE 3.5.8)
Installed from:    Ubuntu Packages
OS:                Linux

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.

As a note, both devices are paired (Allow Always) and also listed so in the applet.

Seems that this wasn't a kdebluetooth bug but a kernel bug. It is at least fixed on Ubuntu since 8.04.1
