other workspaces are blank with no way to switch back

[Dan Connolly]

What I did;
  - upgraded to 14.04 trusty
 - installed gnome-session-flashback
 - logged out; logged in with gnome flashback (compiz)
 - in the lower left corner, right click to bring up preferences; change number of workspaces to 4
 - click on workspace 3

What I expected:
 - a panel (with clock etc.) above and a (mostly) blank taskbar below with a workspace switcher
 - or at least the ability to get back to workspace 1 using ALT-arrow

What I saw instead:
 - a screen completely blank except for the background
 - no way to change workspaces, launch programs log out, etc.

I had to CTRL-ALT-F1 and loging and `sudo /etc/init.d/lightdm restart` to log in again. Of course, I lose my session state.

The symptoms are very much like #156502. That bug was closed as as invalid with an explanation of "This particular bug has already been reported into our bug tracking system" but no reference to the bug that was already reported. If it was already reported, shouldn't the status be something like duplicate?

Odd... the symptoms have gone away. I'm not sure what changed.

As you seem to be not able to reproduce it anymore, I am closing it.
