i further identified the cause, and it is the 'plugdev' group. if the user (include root) is not a member of this group, you will not be able to use the kde widget to change the brightness of the lcd. an even wired issue i found is that, after you joined in the group, you will have to restart the system. log off and log on takes no effect. -- Best Regards, David Shen http://twitter.com/davidshen84/
