Hello, I plan to change the graphic card I've run for years now, which is a Matrox G450 Dual Head (I don't use that feature though), to a GeForce 6200/6200TC from Twintech Graphics (6200 AGP, 256Mo DVI+TV DDR2) What do I have to do to be sure I won't have any problem with that switch ? Do I have to backup something first ? to download a driver (rpm but which one) ? to install something before the switch ? Do I have to keep installed both graphic cards into the computer at least at the beginning ? I run Fedora Core 6. Thank you in advance. Francois --
