Following the advice on Installing QGIS with GRASS plugin on Ubuntu?...
I've installed qgis, qgis-plugin-grass, python-qgis, grass-core=6.4.3-3, grass=6.4.3-3, grass-doc=6.4.3-3, grass-gui=6.4.3-3
I open qgis, but there is nothing about GRASS in the plugins menu.
scott@beast:~$ apt-cache policy qgis
