I am using Ubuntu 11.4 alpha3 just to test it. Unity desktop loads without top panel and left dock.

After some help I got this command and tried it.

unity --replace

Here is the output

unity-panel-service: no process found
libcompizconfig: dlopen: /usr/lib/compizconfig/backends/libgconf.so: cannot open shared object file: No such file or directory

This file is locate at /usr/lib/gnome-settings-daemon-3.0/libgconf.so

Try running this command:

unity --reset

Also, make sure you have the compiz-gnome package installed. This package contains unity-window-decorator. Run this command to ensure that compiz-gnome is installed:

sudo apt-get install compiz-gnome

Ya, it was compiz issue, it was there but with some conflict, reinstalled and fixed. :) –  Shuaib Nawaz Mar 29 '11 at 6:58
