HELP: I am installing centos 4 and X will not start. The first error I was getting after loading the live cd was depth 12 not supported. I edited xorg.conf and set the depth to 24. I no longer get errors which shut down X, but I now get X to load with the mouse curser, but no graphics. If I Cntrl Alt Backspace and stop X, and look at the log, xorg.conf will not rec. the screen? Any ideas?
