I recently installed XFX geforce 6200 AGP card on my system. I managed to boot into linux. I set resolution to 1024x768 and logged out. Then I was not able to go to GUI mode. What can be problem? How can I change resolution from shell prompt. I use Mandrake Linux 10.1. I installed the latest NVIDIA drivers for linux.

open /etc/X11/xorg.conf and edit the resolution there. u can also set default depth there

Google for your monitor's specs...specific to model number..and change accordingly in xorg.conf. Also install the drivers for ur grafix card.
