It is a problem with X and nVidia (AFAIK) chipsets that the mouse cursor is sometimes invisible. The mouse works, you can tell by the icons highlighting and clicking on the icons launches the program. This has been reported in the Redhat and Xorg bugzillas. See the following for details:
https://bugs.freedesktop.org/show_bug.cgi?id=3009
https://bugzilla.redhat.com/bugzilla....cgi?id=182517
This is how you fix it:
1. Open a root terminal session or change to the root account from a standard terminal session.
2. Edit the X Windows configuration file.
Quote:
#gedit /etc/X11/xorg.conf

3. Revise the "Device" section as follows (edit the line in red):
Quote:
Section"Device"
Identifier "Videocard0"
Driver "nv"
VendorName "Videocard vendor"
BoardName "nVidia Corporation C51 PCI Express Bridge"
## Fix Redhat Bug #182517
Option "HWCursor" "off"
EndSection

4. Save the file and exit gedit.
5. Log out and log back in. Your mouse pointer should be restored.
