Can t type x character in console while beeing non-root

[xorax <ivan.ru@gmail.com>]

Using Debian 4.0, xorg, xfce.
I can t type  x  character in console (Alt-Ctrl-F1) as well as in X-
terminal-emulator while beeing logged in as non-root user. As soon as
I make  su  or log in as root I become able to type it.

That s weird! Can anyone suggest anything?

PS. Here is my keyboard config:
Section "InputDevice"
        Identifier      "Generic Keyboard"
        Driver          "kbd"
        Option          "CoreKeyboard"
        Option          "XkbRules"      "xorg"
        Option          "XkbModel"      "pc105"
        Option          "XkbLayout"     "us,ru(winkeys)"
        Option          "XkbOptions"
"grp:ctrl_shift_toggle,grp_led:scroll"
        Option          "XkbOptions"    "250 30"
