Thank You vermaden, and BSDfan for your help.
Thank You DrJ the driver worked wonders
i first removed the old one
silly_wabbit # pfexec pkg uninstall NVDAgraphics
then installed the new one with
code
silly_wabbit#sh NVIDIA-Solaris-x86-173.14.12.run
All went well i changed nv to nvidia in the xorg.conf file
i did not have to fiddle with anything else.
Glx loaded fine and the miraculous Nvidia splash screen
came up at last when i reboot - --
all glx screensavers work flawlesly now
i like this thank so much for all your help
