WARNING: Your driver installation has been altered since it was initially
installed; this may happen, for example, if you have since installed
the NVIDIA driver through a mechanism other than nvidia-installer
(such as your distribution's native package management system).
nvidia-installer will attempt to uninstall as best it can. Please see
the file '/var/log/nvidia-installer.log' for details.
