Move mouse between monitors

Do you have a dual monitor setup with Ubuntu and you have difficulties moving the mouse or dragging the windows between the two monitors? You can resolve the problem by disabling certain plugins from Compiz, or by the next easy trick:

Copy and Paste in terminal

When working in terminal you may notice that you can not use the usual  Ctrl + C  and  Ctrl + V  commands. Instead, use  Ctrl + Shift + C  to copy and  Ctrl + Shift + V  to paste. It is very handy when copying all those command examples from internet.

There is, though, another "fancier" way to copy and paste text in the terminal and in linux in general, and this one uses a second clipboard to remember your selection:

to copy : select the text with the mouse cursor (it is automatically copied to the second clipboard);

to paste : press middle mouse click and the above selected text will be pasted;

alternate paste (in case you don't have middle button on your mouse) :  Shift + Ins .

You may find quite useful to have two separate clipboards for temporary storing copy-paste information.

Roll up window with mouse wheel

If you didn't knew, there is a nice compiz effect called "shade" that rolls up the window and hides it inside the title bar. It can be used as an alternative to minimizing a window so you have it around without occupying much space. More over, it is active by default lately in most of Ubuntu distributions (or at least 12.04 according to my experience) and it can be activated by pressing this special combination of keys:

Drag window to another workspace

When using multiple workspaces, dragging one window from one work space to another would seem the obvious thing to do.

Ubuntu on tablets

Big news from Canonical today: finally Ubuntu for tablets; the only device not yet officially under the Ubuntu umbrella until now. It is supposed to come with the new Ubuntu for phones flavor, but with the capability to take advantage of the bigger screen. The navigation is touch based but if you plug in a mouse and keyboard the classical Unity will appear on the screen.

Print screen

Two advanced print screen commands in Ubuntu:

Alt + Prt Scr = print current window

Shift + Prt Scr = print selection from mouse
