thanks for the pointer. It now works perfectly. There are 2 splash screens that NVIDIA offers when starting up the OS (text and GUI stages). Those are not so anoying. I had to install some kernel rpms in order to compile the driver. It seems that I now have 3 images like so:
title Fedora Core (2.6.18-1.2868.fc6)
kernel /boot/vmlinuz-2.6.18-1.2868.fc6 ro root=LABEL=/ rhgb quiet
title Fedora Core (2.6.18-1.2868.fc6xen)
module /boot/vmlinuz-2.6.18-1.2868.fc6xen ro root=LABEL=/ rhgb quiet
title Fedora Core (2.6.18-1.2849.fc6xen)
I would like to remove the oldest version. I guess these are kernel images; can you tell me how can I uninstall one?
