1) First of all, get your Notes .DEB file and install it. If you get a message about a dependency that can't be fulfilled, just search for the name of the library on google -- you'll find a link to it right away (usually on Ubuntu's servers, directly). Download it and install it, and then restart the Notes .DEB. (In my case it was libgnome-desktop-2 -- perhaps Notes 8.5.1 is looking for a few Ubuntu 8.04 libs?)
2) When it's done installing, download the file from this location, and unpack it:
3) There are four files contained therein.
libgdk-x11-2.0.so.0Give them root ownership and 755 permissions, and place them in "/opt/ibm/lotus/notes". Just a few commands like:
sudo chmod 755 *.so.0 sudo chown root:root *.so.0 sudo mv *.so.0 /opt/ibm/lotus/notes
from inside the folder you unpacked should do the trick.
4) Start Lotus Notes. No, that's it -- no more steps.
Steps 2 and 3 are necessary because, for some reason, these files aren't included with the Notes installation, and if you start Notes without having copied those four files over, nothing will display. Not documents, not applications, not your mail file -- nothing. It's like nothing is being rendered.
At first I thought it may have been a problem with some sort of renderer that Notes is expecting to work a certain way, and since my Ubuntu install was heavily modified and hacked, I figured it was my fault. So, I started up a virtual machine with a fresh install of 10.04, but no -- same problem.
