I am about to take the big step of trying , once again, to install my NVida GT240 Graphics card. Last time I had no end opf trouble that always resulted in me having to reinstall Fedora 21 but this time, I really cannot afford to do that..... SO..If I install the driver, either Via RPM or Via NVida download ( which is recommended? ) How can I revert to the on-board card if the NVida causes my system to crash as it did last time ?

Also, do I need to get the system into a basic VGA mode before I try the install and if so, please can you explain how I get there.

Many thanks in advance

You could use http://rpmfusion.org/ to install the nVidia drivers. If they fail to work, log in to a text terminal and remove them, and restore the free (nouveau) drivers.

eg:

To install, first set up RPMFusion Free & Non-Free by clicking the links on their site. From a Terminal (in X), you can install with pkcon install kmod-nvidia x11-xorg-drv-nvidia, then reboot.

If you don't get a login (or things are really messed-up):

Hit Control+Alt+F6 to revert to a text terminal login Log in as your (administrator) user account Enter rpm -qa | grep nvidia — to see what packages you may wish to remove. Use sudo dnf removexorg-x11-drv-nvidia kmod-nvidia … listing whichever packages you want to remove Confirm the removal; then sudo dnf install xorg-x11-drv-nouveau to install the free version. You'll probably have to reboot again.

Caveat emptor; I'm writing this from memory…
