Comment 22 for bug 278078

i've got this problem as well after updating Intrepid beta from Hardy.
in the result of xprop, evdev was appeared...

$ xprop -root | grep XKB
_XKB_RULES_NAMES_BACKUP(STRING) = "evdev", "jp106", "jp", "latin", "grp:alt_shift_toggle,grp_led:scroll,ctrl:nocaps"
_XKB_RULES_NAMES(STRING) = "evdev", "jp106", "jp", "", "grp:alt_shift_toggle,grp_led:scroll,ctrl:nocaps"
$ gconftool-2 -R /desktop/gnome/peripherals/keyboard/kbd
 layouts = [jp]
 model =
 options = []

once executing "setxkbmap latin", the layout became like pc105...
however the followings cause some errors:
$ setxkbmap pc105
Error loading new keyboard description
$ setxkbmap pc101
Error loading new keyboard description
$ setxkbmap jp106
Error loading new keyboard description

Some related parts of /etc/X11/xorg.conf on my computer are also shown as follow:
----
Section "InputDevice"
 Identifier "Generic Keyboard"
 Driver "kbd"
 Option "CoreKeyboard"
 Option "XkbRules" "xorg"
 Option "XkbModel" "jp106"

 Option "XkbVariant" ""
 Option "XkbOptions" "grp:alt_shift_toggle,grp_led:scroll"
EndSection
