kudzu is Obsolete and no longer part of Debian

Debian now does the same job as kudzu in different and better ways.

Used to be one might have to use the ddcxinfo, from the kudzu package to generate a hopefully valid and optimized Monitor-entry for XF86Config-4. Nowadays, Xorg can usually auto-detect the appropriate configuration.

To reconfigure XOrg, you can use dpkg-reconfigure xserver-xorg
