I have been trying on Kubuntu 13.04, 13.10 and now 14.04 - but always the same problem!
The mouse works with my android mobile phone.
I use Kubuntu 14.04 here now.
When I press the "connect" button on my mouse, I cannot find it using KDE Bluetooth manager, thow rfkill list
tells me, it's not blocked.
So I do rfkill block bluetooth && rfkill unblock bluetooth
. Now the bluetooth icon appears in de tray area. I press the "conect" button on the mouse, it appears in the list, and I can finish pairing. Now everything works for 1 or 2 minutes, until the mouse won't work anymore. The tray icon still says "connected". I can also see the laser sensor flashing.
I am sorry I have no idea how to show the kind of bluetooth chipset I have, and also don't know how to debug the connection.
Please help me ;)
David.
