Default No input devices in wheezy +additional info #2

My keyboard works fine at the GRUB screen, enabling me to select the

Doing a hard reboot, I can boot into recovery mode and from there
startx and as root, keyboard and mouse work fine. But, logging out
as root and coming back to the login screen, again input devices are

Research from the web seems to suggest this is a known bug, but the
resolutions are confusing: some suggest rm -fr /run but that doesn't
work for me; others suggest it is something to do with udev, whilst
others think it has something to do with xorg.conf. So far, the only
workarounds seem to be hacks that work for some but not for others.
There do seem to be a number of bugs reported on this already.

I am currently using my user account, but had to get into it via
recovery mode, going to root and su to my user account. This seems
to be okay, but it is not a preferred route.

Can someone please give me some advice on how to fix this.

Am I looking at downgrading udev or upgrading it or ... ? And if
downgrading it, how do I do that without losing everything else that
seems to be dependent on it?

For reference, this is an installation from squeeze that was updated
to wheezy, but I have now read that this is an issue for those who
have done fresh wheezy installs as well.

Thanks for any help.


Additional info if helpful ...

No name brand PS/2 keyboard 105 keys intl

Logitech USB marble mouse

Problem can be replicated using an alternate USB keyboard (Logitech).

Thanks again.


Some additional info, but am not sure of the relevance, so ...

* There is no xorg.conf file present in the system, but xorg 1:7.6+6 is

* A recent update installed GRUB2-common (although grub2 and grub are not)
* HAL is not installed
* udev is 170-1
* problem not fixed by removing and replugging keyboard/ mouse at login

anyone ... ?
