you have mandrake 9.1 right?
you should do as I posted before: reinstall the driver the right way:
the problem is that the module isn't loaded at boot time.
you should go to text mode with CTRL-ALT-F1 and log in as root
sh NVIDIA.........run //install nvidia again
vi /etc/XF86Config-4 //change nv to nvidia press 'INS' to edit; 'ESC:wqENTER' to exit
execute these commands without anything in between!!!
if you do this, your problem WILL be solved for ever!
