No action for keyboard on YOCTO

[Xiaofeng Yan]

Hi all,

I had a trouble with no action for keyboard when running command 
"Xfbdev" on qemuarm and OS is yocto, the version is 1.4.4

The detailed steps are follow:
$Xfbdev :0 -keybd keyboard -mouse tslib

When I type keys on keyboard, the information on screen are follow:
driver Linux console keyboard wanted to post scancode 78 outside of [0, 0]!
driver Linux console keyboard wanted to post scancode 55 outside of [0, 0]!
......


My configuration for compiling xorg-kdrive is as follow:
  "--enable-composite --enable-kdrive \
                  --disable-dga --disable-dri --disable-xinerama \
                  --disable-xf86misc --disable-xf86vidmode \
                  --disable-xorg --disable-xorgcfg \
                  --disable-xnest --disable-xvfb \
                  --disable-xevie --disable-xprint --disable-xtrap \
                  --disable-dmx --with-xkb-output=/var/lib/xkb\
                  --with-default-font-path=built-ins \
                  --enable-tslib --enable-xcalibrate \
                  --disable-glx \
                  ac_cv_file__usr_share_X11_sgml_defs_ent=no"

   Who can tell me how to solve this problem?

Thanks
Yan
