After a few googling, i found that the community identified this as a problem about my ill-fated xkbcomp. To fix this, they say I have to replace xkbcomp with a fresh one. I did that but it does not work. With a few try-out. I notice that it might be a problem about the keymap file so I replace the old /usr/X11R6/lib/X11/ with the one from my FC4. That solves all the problem.
