However, after suspend and resume the mouse fails to reconnect. It does "attempt" to reconnect, in that I see the padlock flashes momentarily onto the bluetooth icon on the toolbar applet. Similarly, if the Bluetooth Settings dialog is open the devices flashes momentarily bold as if connected. Both effects happen whenever the mouse is used (movement or mouse click) but the device does not connect. I have a workaround, which is to remove the device and pair it using the command line as follows: sudo bluez-test-device remove 00:1F:20:EF:B1:00 sudo bluez-simple-agent hci0 00:1F:20:EF:B1:00 remove sudo bluez-simple-agent hci0 00:1F:20:EF:B1:00 sudo bluez-test-device trusted 00:1F:20:EF:B1:00 yes sudo bluez-test-input connect 00:1F:20:EF:B1:00 Once paired manually in this manner the devices appears in the Bluetooth Settings as normal an successfully reconnects when resuming. I'm submitted a new bug as this is similar but not the same as other bugs reported. In particular the workarounds presented in other bugs do not work for me and the workaround I'm using was not suggested in other cases. Thanks.
