Re: x.org issues - (EE) No devices detected.
Thanks for the suggestion, but that doesn't help, in that 'make cloneconfig' failed to work.
I'll take a look at the BIOS next time I reboot. So the values should be the opposite of what you wrote in your message to which you linked? If I change these, are they likely to affect my Win2000 installation (I'd prefer not to have to worry about flicking back and forth between settings when booting)?
As mentioned, the weird part is that with XFree86 there was no issue.
