If I'm not mistaken, there's an even easier way: If 'apt-get install' or 'apt-get remove' doesn't see a package matching the requested name, and the requested name contains one of a few specific characters (see the man page), it treats the requested name as a regular expression to be matched against the complete package list. Therefore, apt-get remove ".*lxde.*" would probably have worked in this case. -- The Wanderer The reasonable man adapts himself to the world; the unreasonable one persists in trying to adapt the world to himself.
