Unity sidebar gone after update (with Nvidia) 15.04

[pt3lford]

Hi,
Every couple of weeks one of the regular updates seems to break my install. Typically this results in me re-running the NVIDIA installer and all is well.

This time re-running the installer has given me back the ability to log in, but unity has disappeared (the side bar and top bar). I'm currently using twm as a workaround, but its not ideal.

My .xsession-errors has the following:


upstart: upstart-event-bridge main process (1914) terminated with status 1
upstart: upstart-event-bridge main process ended, respawning
upstart: upstart-event-bridge main process (1936) terminated with status 1
upstart: upstart-event-bridge main process ended, respawning
..

upstart: indicator-printers main process (2113) killed by TERM signal
upstart: indicator-session main process (2114) killed by TERM signal
upstart: indicator-application main process (2125) killed by TERM signal

and I have a _usr_lib_unity_unity-panel-service.2000.crash file in /var/crash

Trying to start unity from a terminal seems to hang around here:

compiz (core) - Info: Starting plugin: session
compiz (core) - Info: Loading plugin: snap
compiz (core) - Info: Starting plugin: snap
compiz (core) - Info: Loading plugin: commands

compiz (core) - Info: Loading plugin: mousepoll
compiz (core) - Info: Starting plugin: mousepoll
compiz (core) - Info: Loading plugin: imgpng
compiz (core) - Info: Starting plugin: imgpng

Not really sure where to start. I have tried apt-get update, package repair, but so far no real progress.

Thanks,
Peter.
