Save downgrade of xf86-input-evdev

Hi, after updating to newest x-org 1.7 (and other packages too, including xf86-input-evdev 2.3.1) i noticed several issues:

- i cant' use touchpad, cuz cursor moves all the time to top-left corner of screen once i put the finger away
- external USB mouse sometimes won't hotplug corretly and above issue is present, i need to re plug it
- sometimes whole X crashes and reverts me back to GDM login screen
- sometimes USB mouse isn't working at all after repluging, like no power is transmitted
- bluetooth and webcam isn't detected at all anymore

Regarding to other threats, i assume it's related to xf86-input-evdev 2.3.1 package, so i used that wiki to downgrade it:

http://wiki.archlinux.org/index.php/Downgrade_packages

It says:

How to downgrade a package
Q: I just ran pacman -Syu and package XYZ was upgraded to version N from version M. This package is causing problems on my computer, how can I downgrade from version N to the older version M?
A: You may be able to downgrade the package trivially by visiting /var/cache/pacman/pkg on your system and seeing if the older version of the package is stored there. (If you have not run pacman -Scc recently, it should be there). If the package is there, you can install that version using pacman -U pkgname-olderpkgver.pkg.tar.gz.

This process will remove the current package, it will carefully calculate all of the dependency changes, and it will install the older version you have chosen with the proper dependencies down the line.

So i did:

pacman -U xf86-input-evdev xxx

(i don't remeber previous version)

It was only one package downgraded, so i reboot my netbook. After that, no mouse or keyboard is working anymore, i can do nothing.

SO

How can i login into my system, and safely downgrade xf86-input-evdev including all dependencies?

Reboot and when you get to the grub screen press "e" to edit the kernel line.  Add the word "single" to the end of the line, press enter and then "b" for boot.  You will then go into single user mode and will be able to use pacman to correct the problem.

Re: Save downgrade of xf86-input-evdev

I think you also need to downgrade xorg-server and friends.

pacman -U /var/cache/pacman/pkg/xorg-server-1.6.3.901-1-i686.pkg.tar.gz \
/var/cache/pacman/pkg/xorg-server-utils-7.4-7-i686.pkg.tar.gz \
/var/cache/pacman/pkg/xf86-video-intel-legacy-2.3.2-3-i686.pkg.tar.gz \
/var/cache/pacman/pkg/xf86-video-vesa-2.2.0-1-i686.pkg.tar.gz \
/var/cache/pacman/pkg/xf86-input-evdev-2.2.5-1-i686.pkg.tar.gz \
/var/cache/pacman/pkg/xf86-input-keyboard-1.3.2-2-i686.pkg.tar.gz \
/var/cache/pacman/pkg/xf86-input-mouse-1.4.0-2-i686.pkg.tar.gz

I have an Intel card, if you don't - adjust (or simply remove) the line accordingly.

Re: Save downgrade of xf86-input-evdev

Thanks, You saved me for now.
Unfortunatly bt and webcam is not working, i'll take care of it later.

It seems i didn't have input-keyboard and input-mouse installed (they weren't present in cache), so i gabbed them from http://www.schlunix.org/archlinux/extra/os/i686/
Did i right?

I use Arch on MSI Wind u100 netbook, if it does matter.
