[SOLVED] Xorg doesn't pick up any input devices from udev

My laptop is an Acer Aspire One D255.  With a fresh install of Arch, Xorg doesn't pick up any input devices from udev.  The keyboard and trackpad both work in the linux console.  Killing gpm has no effect.  I would post my xorg log, but it's terribly uninformative.  There is no mention of anything evdev or input related other than the standard message:

[222367.704] (II) The server relies on udev to provide the list of input devices.
        If no devices become available, reconfigure udev or disable AutoAddDevices.

I've tried various tweaks to xorg.conf and udev rules, but nothing seems to have any effects.  I don't know if this is related, but xinput refuses to connect to the xserver, so `xinput list` doesn't provide anything useful either.

Has anyone seen this before?

Re: [SOLVED] Xorg doesn't pick up any input devices from udev

Input driver wise, I have evdev and synaptics, but neither even get loaded unless I specifically request them in my xorg.conf.  But even when I do that, they still don't pick up any devices.

I tried installing the keyboard and mouse drivers, which do work for the time being as a workaround, but I would rather use evdev/udev so I can hotplug my USB mouse.

Re: [SOLVED] Xorg doesn't pick up any input devices from udev

Xorg package versions:
http://pastebin.com/Fu2gpdYD

udev is 166-2

Keyboard info:
http://pastebin.com/zkZdFTmW

Trackpad info:
http://pastebin.com/X9sPXcau

Let me know if there is any other info that could be helpful.

EDIT: thought I'd add:
My xorg.conf and udev rules are all stock.  I've tried playing around with them to no avail so I'm back to stock settings.

`xorg -configure` produces a broken configuration.  It tries to statically configure the keyboard and mouse, but doesn't set "AllowEmptyInput" "false" so I end up with the same problem.

Video works flawlessly out of the box so that's not an issue.

Like I said, nothing relating to input at all.

Note that the custom kernel is necessary, the stock Arch one is horribly broken for my netbook.  I intentionally left out fbdev as if it's present it steals control from the intel driver in the linux console, preventing KMS from working.

EDIT: another thought:
I'm not at home so I can't test this now, but if I have keybdev and mousedev compiled in, could they somehow interfere with evdev?

Re: [SOLVED] Xorg doesn't pick up any input devices from udev

Re: [SOLVED] Xorg doesn't pick up any input devices from udev

Unfortunately none of the AUR aspire one kernels are for my machine.

For what it's worth all the input related flags are identical, the configurations mainly differ in networking.

Re: [SOLVED] Xorg doesn't pick up any input devices from udev

Something must have went wrong during the initial installation of udev - after a reinstall it works perfectly.

Thanks for trying to help.
