I am running Ubuntu 12.10 Quantal on a machine that is more than powerful enough to support unity.

First off, my setup: GUI boot is disabled. I boot into tty after which I use sudo lightdm to get to the desktop, I have bumblebee installed to enable Optimus for my nVidia GT 540M graphics card.

I have enabled edge triggers in CCSM. Since the edge trigger settings were not being remembered after every login, I was advised to add the following entry to my startup:

bash -c "sleep 3; compiz --replace"

Now it so happens that sometimes, "Unity will randomly fail to load. I get a blank desktop with no titlebars or window edges. I have to right click and open wallpaper settings, this somehow enables me to use Ctrl+Alt+T to launch the terminal. Here, typing sudo unity --replace does cause unity to start but all none of my settings are stored, some buttons are missing etc. Further, other attempts to start terminal run it as root and not as my username. However when I disable and re-enable Unity through ccsm, my desktop returns to normal after a reboot. The problem is not even consistent. I am not sure as to what is the cause here. Could it have something to do with the startup entry?

Any help will be appreciated.

Okay, update. Now I can use the terminal to type in unity --replace and it works fine. But not automatically. –  Milo S Oct 21 '12 at 10:48
Still looking for an answer? I recommend upgrading to a newer version of Ubuntu. –  Seth Jun 23 '14 at 22:45
