How strange! I can see that having taken a while to figure out. > What differences would installing Xfce 1st make that installing gnome > over the top make? (Just so I can report a bug to them) By default recent Debian now configures apt to install Recommends: by default. When a package is installed apt will install any Depends: and Recommends: for that package. (Many of us turn off the installation of Recommends:.) When an individual dependency is installed it may not be a simple dependency on "foo". It may be "foo | bar | other". If I contrive an example package "package1: foo | bar" and "package2: bar" and you install package1 first you will get: package1 foo Then if you install package2 you get: package1 package2 foo bar But if you install package2 first then package2 will pull in bar. package2 bar Since bar is now installed apt will assume that is what you want. The dependency of package1 is satisfied by bar. So now with package1 it doesn't need anything else installed. package1 package2 bar I hope that explains at least one case where the order of installation will affect the end result of what you have installed. To debug this further I would install one way and collect a full list of installed packages. Then install the other way and collect a second full list of packages. Then compare the two lists. What that should yield is a difference. Probably a missing package. If you then install the way that isn't working and then install the missing package it should work the same as the other way. If it is only due to the missing package. Another possibility is that the order of installation will leave the state in the configuration of the last package to be installed. There are some "debian-alternatives" that have equal priority. For alternatives of equal priority the last one installed takes precedence. (If alternatives have different priorities then the highest priority takes precedence.) http://wiki.debian.org/DebianAlternatives And I am sure there are other potential differences too. Bob
