I'm beginning to suspect some kind of wierd hardware failure, frankly. I hadn't rebooted the computer for quite some time (more than a month, I think) prior to trying to work out this usb thing. The first time I rebooted it after tinkering with usb stuff, I got a pause and the "no signal" message on the blank monitor for a second or two before xdm appeared. I was actually a bit disturbed by it momentarily - sort of in preparation for an "oh no, what's wrong" feeling, though the eventual appearence of xdm preempted that. But on subsequent reboots, xdm does not finally appear. What kind of hardware problem this could be is beyond me: as I said, booting from Knoppix that display looks fine when the gui comes up - apart from being 1024x768 rather than the 1280x1024 this monitor is supposed to run at. Just some further reflections on this strange situation. Further feedback appreciated.
James PS I can still boot from a 2.4.x kernel on the system - though I'll be without mouse support. Maybe I should try that? - To unsubscribe from this list: send the line "unsubscribe linux-newbie" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.linux-learn.org/faqs
