What we will need:
- a desired cursor theme (can be obtained from either http://gnome-look.org or just about any website, like http://deviantart.com
- dconf-tools package from synaptic
How to do this:
1. Download your desired cursor theme and extract it to /usr/share/icons (you need root privileges to do that). The correct package needs to have an index.theme file inside.
2. Open up Gnome Tweak Tool, go to Theme's tab and change your cursor to the latest theme you downloaded.
3. Check the name of the cursor theme how it's displayed in Gnome Tweak Tool, make it match exactly as in system settings below in the index.theme of the cursor by opening it as root in the following location:
/usr/share/icons/default/index.theme
or using the command "sudo gedit /usr/share/icons/default/index.theme"
There should be a line labeled "Inherits" containing the name of the cursor theme. By default it's DMZ-White.
4. Last step is checking in system settings. The package in order to access system settings is called "dconf-tools" in Synaptic Package Manager. Download and install it.
To launch it, use ALT + F2 and type in "dconf-editor" (without the quotes). Navigate to:
or ORG > GNOME > DESKTOP > INTERFACE
The name in system settings should be the same there and in the index.theme file. Which means in system settings I currently have "oxy-neon", the same needs to be in index.theme file in Inherits section.
5. Once done, logout and log back in to your session, or hit CTRL + ALT + BACKSPACE. Hope this helps.
