uname -r output:
This laptop 's got several kernel versions appearing on startup. That's so since I updated the Nvidia GPU's driver suit.
I don't think this problem occured after an update or anything. I don't remember making any basic update in between. I might have just installed some application such as Quicktime player, though.
UPDATE: I solved the problem after this: I have removed those mouse and the headset I'm talking about in Bluetooth Preferences section and run Setup New Device for them again and it worked, finally!
