Mouse Cursors in Ubuntu 11.10

First of all you have to install this program (for gnome 3) by typing

 sudo apt-get install gnome-tweak-tool

In Ubuntu Software Center it's called "Advanced Settings", (you can search "tweak" and you will find it)

The best Place to download cool and new cursors is here: http://gnome-look.org/index.php?xcontentmode=36

If you downloaded "*.tar.gz" file you should extract it with the command

tar -zxvf *.tar.gz

(where "*.tar.gz" is the file name)

After extracting *.tar.gz file or files it will create a directory with the name of the mouse cursor.
Next you need to copy those folders or folder to  /usr/share/icons/ but you need root permission to do this. The easiest way to do this is using nautilus as root, just type in terminal

sudo nautilus

and enter password, now just copy those folders

Now open "Advanced Settings" and go to Theme then choose

  

you should find your new and old mouse cursor at "Cursor theme".

Now in Terminal enter the following lines:

sudo update-alternatives --config x-cursor-theme

and select by number your new cursor.

If you can't find your mouse cursor in this list you just need to enter this line (after pressing enter to exit)

gksu gedit /usr/share/icons/default/index.theme 

and at the line Inherits change after "=" sign to the name of your cursor name after doing so you just need to logout and login back, do not continue this tutorial because you already done !!!

Before the next command you should close all you opened programs because it will demand logging out of your user and you should already have COMPIZ installed (just search for it in the ubuntu software center).

compiz --replace

If you like me and after executing this command can't see the menus you should log out using CTR+ALT+DEL , or CTR+ALT+BACKSPACE
After you login again your mouse cursor should be new and work in all windows and applications.
