INSTALLATION question about nvidia drivers


to install the proprietary drivers must be change before the grub?

SDB:NVIDIA drivers - openSUSE

I do not understand where I put the option nomodeset

You have to edit the file /boot/grub/menu.lst (Ort manually add it in the boot line)
There is another guide here:
Nvidia for Newbies part 1

Or boot in to safe mode
