I just installed RHEL on a PC with both an onboard 810 AGP 16MB graphics chipset and an ATI Radeon 7200 with 32MB of RAM. During the install, Linux detected my graphics card as the former (AGP 16MB) instead of my Radeon. I changed thsi to the proper setting when prompted during the install. Now, when I boot into Linux, I see the verbose setup, but then the screen goes blank when it tries to change to the GUI. How can I fix this? Is there a way to try and reinstall the graphics card hardware? The monitor was configured correctly, and I did not change it from what Linux had probed during the install, so I dont think that's the issue. Any help is appreciated, thanks.
