Binary package hint: x11-common

Ubuntu 6.06.1 LTS (Dapper Drake) uses the x11-common 7.0.0-ubuntu4 package to provide "X Window System (X.Org) infratructure". When configured with debconf, this package generates an /etc/X11/Xwrapper.config file which contains the following text:

# Xwrapper.config (Debian X Window System server wrapper configuration file)
#
# This file was generated by the post-installation script of the x11-common
# package using values from the debconf database.
#
# See the Xwrapper.config(5) manual page for more information.
#
# This file is automatically updated on upgrades of the x11-common package
# *only* if it has not been modified since the last upgrade of that package.
#
# If you have edited this file but would like it to be automatically updated
# again, run the following command as root:
# dpkg-reconfigure x11-common
