Launcher bar in purple and only has icons for dash, trash, and workspaces; keyboard unresponsive, and menu bar empty

Question

Please help me reset or reinstall Unity. I've already tried everything here as well as apt-get update and upgrade. My system entered this state after I re-installed the OS (12.04) in the hopes of curing its instability.

Purple Launcher, empty title bar

The curious thing is that Unity works if I go through recovery mode followed by resume.

Have you tried unity --reset? – Mitch Sep 06 '12 at 18:07 — Mitch, Sep 06 '12 at 18:07
And a LOT more. Please refer to link in question. – Emre Sep 06 '12 at 18:08 — Emre, Sep 06 '12 at 18:08

Try this. Just press Ctrl+Alt+T on your keyboard to open Terminal. When it opens, run the commands below.

sudo apt-get purge unity && sudo apt-get install unity

Reboot your system.

If the above does't help, try

sudo apt-get install --reinstall ubuntu-mono ubuntu-minimal ubuntu-desktop unity unity-common unity-2d

No change. Maybe some logs would help? – Emre Sep 06 '12 at 18:14

The problem was the simultaneous use of three video outputs (HDMI, VGA, and DVI) when only two can work at a time. I simply removed one of them and it booted right back up. Now that it is working I can re-attach all three and choose which two I want from the display settings.
