I am a first-time Linux user who has installed Ubuntu 12.04 on a Dell Dimension E510 that used to run Windows XP. I cannot get Dash Home to open. The other apps open: Firefox, Libre Office, etc., but when I click Dash Home the screen flickers a couple of times and no dash opens. No window with search bar and whatever else is supposed to be there. I have tried several of the suggestions in this forum, but nothing has helped. I have also reinstalled Ubuntu from the boot disk, but Dash still will not open. Does anyone have a solution that can be communicated clearly? I will not understand much Linux terminology.

Try resetting unity 

unity --reset

if that doesn't help then try this

sudo apt-get update

sudo apt-get install --reinstall ubuntu-desktop

sudo apt-get install unity

Hope this helps!

I am answering my own question. Sorry if that is irregular. Apparently the problem is my hardware. I installed Ubuntu 12.04 to a newer, faster computer, using the same disk and everything seemed to work; at least Unity Dash Home opened. For the record; Dell Dimension E510 desktop, 1.0 GB RAM, 245 GB HD, 32 bit system, Pentium D 2.8GHz x2 processor. I gather the RAM is the problem, as I read elsewhere in this forum that 2.0 GB is needed for Unity.
