No keyboard in X / No kernel modules

[MickeyKnox]

I have no keyboard or mouse in X. In a terminal it works though.
Sound doesn't seem to work either, although it used to work.
Network is still working.

I think the reason might be, that there are no kernel modules loaded. lsmod returns nothing (except its header).
I have have no idea what happened.

How can i track down the problem?

Immediately? Make sure that your running kernel and installed kernel match.

$this->bbcode_second_pass_code('', 'pacman -Ss linux-raspberry
core/linux-raspberrypi 3.12.20-3 [installed]')

$this->bbcode_second_pass_code('', 'uname -a
Linux butler 3.12.20-3-ARCH #1 PREEMPT Sun May 25 17:24:25 MDT 2014 armv6l GNU/Linux')

The running kernel has an ARCH postfix, but the version is the same. I'm not sure, do they match?

How is it possible that they not match? What might i have done wrong?

[WarheadsSE]

They do appear to match.

[MickeyKnox]

Ok, so they match. Now what?

Something weird is going on if lsmod shows no modules at all.

Did you try sync and then reboot and examine dmesg output or your logs?

If X does not see your keyboard, the config files in /etc/X11 might need tweaking.

Or, possibly the display number or device mount point has changed. X is very picky, it won't recognize anything or even start if it expects the monitor on /dev/fb0 and somehow your monitor ended up on /dev/fb1

See if it's a permission problem, run X as root

[MickeyKnox]

Running X as root didn't change anything.

pacman is syncing the filesystem after an upgrade, right? I usually did not sync before a reboot.
(sync meaning to enter sync in a terminal, right?)

I did not fiddle with the x server configuration. /etc/X11/xorg.conf.d/00-keyboard.conf looks like this:
$this->bbcode_second_pass_code('', '# Read and parsed by systemd-localed. It's probably wise not to edit this file
# manually too freely.
Section "InputClass"
Identifier "system-keyboard"
MatchIsKeyboard "on"
Option "XkbLayout" "de"
Option "XkbModel" "pc105"
Option "XkbOptions" "terminate:ctrl_alt_bksp"
EndSection')
X starts fine though, apart from not receiving any input. The only thing i can do is to enter 'pkill X' in an ssh shell.

I couldn't make much sense of it, here comes my /var/log/Xorg.0.log:

and my dmesg output:

I just ran an upgrade and now everything is fine.
