(solved) Mouse And Keyboard Freeze When Launching X

Dear all,

this morning my mouse and my keyboard stopped working on my Dell m1330 running Opensuse 10.3, Kde 3.5.8, everything updated to the latest possible (official) packages, nVidia driver updated (and working), compiz disabled at startup but ready to go under the hood.

My pc boots fine, kde starts, everything works, but mouse, touchpad and keyboard do not "talk" to kde (or gnome or xfce or fvwm or kde4 or whatever session i've tried), but "talk" directly to the linux kernel instead.

hence, kde does not respond to me - but it does respond to itself: if I insert a CD, it recognises it and pops up the autostart window, etc.. - in any way.
HItting alt+F1,F2... sends me to parallel linux sessions off of the X server. As if it wasn't there.

This happened after I updated networkmanager and openoffice_quickstarter. The system froze, I had to shut it down the hard way - powering off. On reboot, everything worked but for the mouse and keyboard no longer recognized by X. (note: keyboard works in text-only mode).

I checked my xorg.conf, and everything is as expected: InputDevice section is allright and as it used to be, all is fine.

BUT it still does not work in any way.
I tried to follow a guide to make a new xconf file (this one: http://www.gentoo.org/doc/en/xorg-config.xml ) but also with the new one I get the very same problem

Keep in mind that my ssytem worked properly, and has done so for 6 months now, flawlessly. Now it DOES work flawlessly as before, but WITHOUT me...

UPDATE: the issue has been solved. It was due to a version mismatching in X packages, due in turn to an incomplete update on the part of YOU. The mismatching made X unaware of input devices.
TO SOLVE: boot in runlevel 3, start Yast, downgrade packages of xorg to match one and only one version (it was 7.2), reboot, done.
