Robin has updated his TomboyBlogposter addin and I have updated my Ubuntu packages correspondingly.
Also fresh: Backports of the Vinagre VNC client for Ubuntu 7.10. It’s not sure whether these will make it into gutsy-backports, since some bigger source change was necessary.
Vinagre obsoletes the old and ugly xvncviewer and has a user interface similar to VMWares Server Console or Workstation (sidebar, tabs, etc.).
Get the packages by adding the line
deb http://ppa.launchpad.net/hanno-stock/ubuntu gutsy main
to your APT sources.list (or use Synaptic 3rd party software tab) or download at my PPA.
Download the .debs for your architecture (i386, etc.) and install with:
sudo dpkg -i packagename.deb
Note that if you install the .debs manually via dpkg you have to install gtk-vnc prior to vinagre.
