[ubuntu] xdebug installed but not displayed in phpinfo page?

view full story

http://ubuntuforums.org – When in run Code: php -v php reports that xdebug v2.2.1 is installed, and Code: php -m displays xdebug in zend modules (with no other modules installed) and in php modules. Neither command gives any errors or warnings. However, when I visit my phpinfo() page, there is no mention of xdebug. I have restarted apache several times without success. Anything else I can try?
