Fedora X86/64bit :: STARTX - Keyboard And Mouse Won't Respond F11 New Install

I'm having trouble installing F11 x86_64, and I'm sure it is something to do with the video card.X will not even start if I have both nvidia quadro FX1700's installed. If I take one out, I can install F11, but it always 'hangs' when it starts X (which is to say, both the keyboard and mouse are locked - until I press the power button, but then it shuts down anyway).I've fiddled inittab so it starts in runlevel 3 so I can at least get in and tinker. There is no xorg.conf in /etc/X11, so I assume the system is building it's own and not quite getting it right (guess work based on other threads with similar symptoms).

I can connect to the system from another Linux machine via ssh, and I can ftp to it. I tried copying the xorg.conf from the other machine, but while it changed the screen resolution (ergo, it had some effect), it still went nuts. Starting X remotely via ssh allowed me to trap the messages, which indicate the lack of HAL has something to do with the problem.service --status-all reports hald stopped; I'm assuming this should not be the case. I've used yum to reinstall hal, but that made no difference. Nor did an update - it was already at the most recent level.F11 was installed from a DVD downloaded vai a bittorrent; the disk checked out ok.

My knowledge is limited, and I don't know what should be in xorg.conf for my machine, although I could type it in from scratch or ftp it across from here. It was 'okay' under F10, happily tolerating both video cards. But it seems to be sulking under F11. In case it matters, I'm doing everything as root; since firstboot starts X, I can't use that to create another userid.

- nomodeset, xdriver=vesa, selinux=0, remove rhgb as boot parameters - all to no avail (although these changes seem to be ignored for the most part anyway);

- start the HAL daemon manually (mine failed to start, as others have reported). It didn't like that! (the output is available, but is enormous)

- startx -configure - simply failed;

- dirconf didn't work;

- I've tried swearing at it during start-up, which turned out to be no more or less successful than anything else, but it was fun.
