"proprietary \"nvidia\" video driver, Nvidia provides indirect "+
"customer support via an online web based support forum. Nvidia "+
"monitors these web forums for commonly reported problems and "+
"passes them on to Nvidia engineers for investigation.  Once "+
"they've isolated a particular problem, it is often fixed in "+
"a future video driver update.\n"+
"The NVNews Nvidia Linux driver forum is located at:\n\n"+

"others who may have experienced the particular problem may "+
"be able to assist.  If there is a real bug occurring, Nvidia "+
"will be able to determine this, and will likely resolve the "+
"issue in a future driver update for the operating system "+
"releases that they officially support.\n\n "+
"While Fedora does not support the proprietary Nvidia driver, "+
"users requiring technical help may also find the various "+
"X.Org and Fedora mailing lists helpful in finding "+
"assistance:\n\n"+
