I've been running 64 bit Toorox for a couple of months now without borking the config files.
Most problems have been small and easily fixed by googling, reading this forum or Gentoo forums until now.
I did a world update and lost my mouse and keyboard which are both USB connected to a Belkin KVM.
I did manage to get my mouse back by deleting my xorg.conf file.
I can't get any keyboard to work either by plugging them into the keyboard PS/2 or usb port.
This is the part of my var/log/Xorg.0.log file that I think is relevant.

[ 27.501] (II) <default pointer>: Setting mouse protocol to "ExplorerPS/2"

Any help would be appreciated.
Thanks

Hi Homeyzzz,

you have to reinstall the following package:Greets

Thanks Joern,

Reinstalling xf86-input-keyboard solved the problem.

Hey there! I think that you first of all should check drivers and install all the required updates. At least that's what they told me in customer support.
