When I installed Kubuntu on my wife's new laptop I entered her name for the initial user account. That results in uid and gid 1000 given to her user. On my desktop, my user has uid and gid 1000, her user has 1001 for both. When exchanging files, even more when setting up an NFS server later, all users on the network should have the same uid and gid on all computers.

That's when I googled and came up with an excellent description for usermod and groupmod that help in that situation.

In addition, I found the -h parameter of chgrp and chown useful, so symbolic links get corrected too, not only the referenced files.

When showing OpenOffice to my wife on her new Dell Inspiron 6400 (which I configured to be more or less the same as the Inspiron E1505n Dell offers in the US with Ubuntu 7.04 pre-installed, and Suzan also successfully upgraded to Ubuntu) I wondered that the Letter Wizard didn't work. I remembered configuring OpenOffice to use Sun's Java5 as JRE on my computer instead of the FSF 1.4.2 version already installed.

Obviously, the wizards do depend on Java, but it doesn't say you need Sun's Java or Java5 ...

So, after installing Sun's Java5 via adept and configuring OpenOffice to use that as JRE, it worked!
