After upgrading my desktop to Karmic Koala I started having some problem with my Notes 8.5.1 installation with window not displaying contents.

Doing a brief Google search I found this thread about a change made in libgtk that breaks Lotus Notes.

The solution is in comment #13: just follow the simple instructions and Lotus Notes will be working again.

Update – Nov, 4th 2009

As pointed out by jklocke, a fresh Lotus Notes installation on Ubuntu 9.10 doesn’t work: Notes won’t start at all.

The solution he found is very simple and quick: Notes cannot find the packages libgnomeprint2.2-0 and libgnomeprintui2.2-0.

To resolve the problem run this command to install missing libraries:

sudo apt-get install libgnomeprint2.2-0 libgnomeprintui2.2-0
