I'm not a fan of customizing my Ubuntu to change the appearance of the mouse pointer But just a few minutes ago, talking with someone I had the idea that the world there are many people who want to understand how you can instead install a nice theme for your cursor. One of the flaws, unfortunately, Ubuntu 11.10 is that it is a little 'more elaborate cosmetic change these aspects of the entire environment but, with a little 'patience and some terminal commands, you can customize everything.
The first thing to do (if you do not already have it) is install Gnome Tweak Tools: You can find inside of 'Ubuntu Software Centre. The second thing to do, however, is arrange for a theme for the mouse. Open the terminal and type:
sudo apt-get install oxygen-cursor-theme oxygen-cursor-theme-extra
In this example, I did install the Oxygen theme that, in my opinion, is very nice. Now run Gnome Tweak Tools and card Theme -> Cursor Theme selected the theme Oxygen just installed. To apply you just have to restart compiz by pressing ALT+F2 and typing:
And the new theme for your pointer will be set immediately! If you want there is also a video that explains step by step installation and configuration.
