Reset system wide cursor theme

If you installed KDE in ubuntu (GNOME based), you may have noticed that when you log back into GNOME, you keep the KDE cursor theme.

To fix this, use update-alternatives like so:

0025|z@zentury ~$ sudo update-alternatives --config x-cursor-theme
There are 7 choices for the alternative x-cursor-theme (providing /usr/share/icons/default/index.theme).

  Selection    Path                                     Priority   Status
------------------------------------------------------------
* 0            /etc/X11/cursors/oxy-white.theme          50        auto mode
  1            /etc/X11/cursors/core.theme               30        manual mode
  2            /etc/X11/cursors/handhelds.theme          20        manual mode
  3            /etc/X11/cursors/oxy-white.theme          50        manual mode
  4            /etc/X11/cursors/redglass.theme           20        manual mode
  5            /etc/X11/cursors/whiteglass.theme         20        manual mode
  6            /usr/share/icons/DMZ-Black/cursor.theme   30        manual mode
  7            /usr/share/icons/DMZ-White/cursor.theme   50        manual mode
