Linux on a Latitude D630. The journey

Here is how you can install Lotus Notes client version 8 on Fedora 9.

First thing you need to do is REMOVE xulrunner from the system (using add and remove) because Fedora 9 comes with version 1.9 and LN only runs with version 1.8.
This means you will also have to remove some other packages that depend on it, like Firefox 3 or Eclipse. I'm not sure about Eclipse but after you remove xulrunner, you can then download Firefox 3 directly from www.firefox.com and it will run with no issues (even with xulrunner not installed).

Next step is to install Lotus Notes. Unpack the tar and run the setup as root.
After the installation is completed, you can call LN from Applications -> Office -> Lotus Note 8. You should have no issues.

One thing I did not test yet is the HTML emails. Not sure if those will work.

Feel free to post any problems you found. I'll try to help as possible.
