Dash does not open

Asked by Leon Arundell

On my second day after upgrading to Precise Pangolin, I click on the Dash icon on the launcher, and the only things that change are:
. a miniscule white shape (possibly an arrow) appears in the right margin of the Dash icon
. The top bar of the screen displays three small circular icons. The "close" icon (red circle with black cross), what appears to be a "minimise" icon (grey white circle with horizontal black line) and a "resize" icon (white circle with black rectangle).

Clicking on these icons doesn't make the Dash appear.

How can I get the Dash to appear?

The first thing you should try is to open the Terminal. You don't need the Dash for it, just press Ctrl+Alt+T.
When it opens, copy the next line into it and press Enter:
/usr/lib/nux/unity_support_test -p

Now see it you system is compatible with Unity 3D.

If it is, run this command. It will reset the Unity environment:
unity --reset

If it is not compatible, go back to the login screen, click the icon next to your name and choose "Ubuntu 2D" in the menu. Log in as usual and Ubuntu will run in 2D mode.

If nothing of this helps, post the output of the commands I gave you.

In a failed attempt to revert to Gnome, I had in the meantime executed sudo apt-get install xfce4

The Dash now works as before.

When I ran the /usr/lib/nux/unity_support_test -p command, I got a "no" to "Unity 3D supported."

I will also try reverting to 2D.

Thanks, Thomas.
