If you use your computer for more than casual browsing and email, you probably use keyboard shortcuts quite a bit. Most serious computer users are familiar with Ctrl-c, Ctrl-v and Ctrl-x (copy, paste and cut respectively). These shortcuts save us a lot of time and mouse maneuvering.
If you use the stock Ubuntu desktop (Unity), there is a keyboard shortcut you need to know about. Press and hold the Super key (aka, Windows key on a PC keyboard). You will get a popup on your screen that stays until you release the Super key. On that popup you will find a treasure trove of keyboard shortcuts you can use to simplify your computing experience.
I love this feature of Unity. It’s only one of the reasons Unity and stock Ubuntu are slowly growing on me and satisfying my daily computing needs in general. Well done, Canonical!
I have a HP Bluetooth Mouse X4000b paired with my internal bluetooth adapter on this ASUS Q500A laptop running Ubuntu 13.04.
Each time I boot the machine, I had to push the pair button on the bottom of my mouse and then select the bluetooth settings icon in the bar top-right on the screen and then turn the connection on. It was frustrating. Why can’t the thing just connect at startup?
Apparently it wasn’t a trusted device.
I found my solution on Launchpad. Rostislav Georgiev wrote:
Basically you need to put your mouse in discoverable mode and then run the following commands in the console:
bluez-simple-agent hci0 XX:XX:XX:XX:XX:XX
bluez-test-device trusted XX:XX:XX:XX:XX:XX yes
bluez-test-input connect XX:XX:XX:XX:XX:XX
Where XX:XX:XX:XX:XX:XX is your mouse Bluetooth MAC address as given by hcitool scan.
After following these instructions (no sudo needed), my mouse reconnected after a reboot. Sweet.
There is apparently a patch and a fix is already in the 13.10 version of Ubuntu. I haven’t gone there yet, so I thought I’d post this in case anyone else was having similar problems.
It’s one thing I love about Linux. There may be the occasional issue, but normally a fix for it can be found.
