1) It does't start x, I have to log-in at the CLI and startx. Before that Alt-CTRL-F7 shows:
mountall: plymouth command failed
mountall: disconnected from plymouth
2) Having started by startx, I immediately ran the updater. Which failed on openjdk-7-jre-headless, and leaves 3 brocken packages. The error message says to use the "Broken" filter for find them. The updater doesn't have a Broken Filter (this refers to Synaptic, I think). Anyway used Synaptic to find the brocken packages, but it refuses to remove them or otherwise.
