If you are wondering, how to open chm files in Ubuntu 10.10, here is a solution for you.
Gnochm has been removed from the repository, and instead replaced by chmsee.
chmsee has the following features.
A chm file viewer written in GTK+
- Uses gecko rendering engine
- Support to open multiple files at once
one difference I feel is you cannot search in chmsee application.
Simply you can install chmsee like
apt-get install chmsee
