The symlink I have deleted was:
I also did the;
~#: cp /usr/lib/tls/libnvidia-tls.so.1.0.7667 deleted.libnvidia-tls.so.1.0.7667
(this file was not referenced in nvidia-install.log)
That enabled me to reinstall the driver, but on first reboot the X will not start;
ERR = not starting xdm, it is not default window manager
It was impossible to restart X (with my knoledge), so I have to --uninstall the driver. After that no more problems. The system work fine with 7667.
