I have exactly the same problem as posted before in this forum:
i.e., I have installed fedora 6 & now when i start it, my screen goes blank few seconds after that "Press I for interactive mode" message appears during startup.
But, unlike the solution posted before in that link i can't find xorg.conf file, I get a shell after entering rescue mode and when i enter 'cd /etc/X11' it shows there's no such file or directory, the same happens if I 'vi /etc/X11/xorg.conf'
What should i do? I have / and /home both as ext2 partition, no seperate /boot partition
