Will that include the GLX driver?
Yes. Follow the instructions on the Nvidia site to install it. You will need to have the gcc compiler installed in order to run it, and you must be in a text console at the time. To get to a text console hit Ctl+Alt+F1 log in as root and then enter ' init 3' After it is installed you must change the driver from 'nv' to 'nvidia' The 'Load glx' line can normally be left as it is. Only change it to 'Load /usr/X11R6/lib/modules/extensions/libglx.so' if you still have problems. I find it convenient to use the text based file manager 'mc' to do the editing. To install it 'urpmi mc' and then enter 'mc' to start it up. derek -- www.jennings.homelinux.net http://twiki.mdklinuxfaq.org
