Bug#589373: xkbcomp is unable to be invoked because X server does not see input devices under xen/dom0

[Wladimir Mutel <mwg@mwg.dp.ua>]

	Hi,

	I have run into exactly the same problem. Earlier we had Lenny system
	with Xen Dom0 and Nvidia driver. It was used both as Xen host and as a
	GUI desktop. Video adapter had broken, and was replaced with newer
	Radeon card (HD4350). Which pushed us to upgrade to Squeeze, as Radeon
	driver in Lenny did not support it (and there was not anything suitable
	in Lenny-backports).

	And so, when the -xen- kernel is booted standalone, without initial Xen
	loader, X server detects input devices and starts well. With Xen loader
	and kernel in Dom0, input devices are not detected. The system has USB
	keyboard and mouse that are visible by lsusb either with Xen loader or
	without. Don't know what else to check and compare. Probably this is
	somewhat related to udev. I would appreciate any advise where to look
	next.
