I installed cairo dock like so

sudo add-apt-repository ppa:cairo-dock-team
sudo apt-get update
sudo apt-get install cairo-dock cairo-dock-plug-ins

after i booted up and selected with graphics effect i couldn't see anything
pop up expect the desktop and mouse after a min or two i power off my machine
then booted up unity but couldn't see anything but the panel which was blue
according to my theme. i purged the ppa and did some extra stuff like so

sudo ppa-purge ppa:cairo-dock-team
sudo apt-get purge cairo-dock cairo-dock-plug-ins
sudo apt-get update
sudo apt-get autoremove
sudo apt-get check
sudo apt-get clean
sudo apt-get autoclean
nautilus --check

it removed everything no error whit the exception of nautilus --check

blade@blade-SATELLITE-L750:~$ nautilus --check
running nautilus_self_check_file_utilities
running nautilus_self_check_file_operations
running nautilus_self_check_directory
running nautilus_self_check_file

running nautilus_self_check_file_utilities
running nautilus_self_check_file_operations
running nautilus_self_check_directory
running nautilus_self_check_file
running nautilus_self_check_icon_container

my question is how do i get unity up and running again

i already tried sudo apt-get install ubuntu-desktop if something got
deleted with out me knowing it. and also unity reset which works. for the dash but after a reboot it wouldn't start up again i also tried sudo compiz --replace but no luck here is the output for compiz --replace

I need my Ubuntu for school work, if i can't fixed this, i am forced to do a clean install of Ubuntu, I like to be able to fix this for other users, and to make the Ubuntu experience more enjoyable. –  blade19899 Apr 18 '12 at 10:24

thanks in the link the answer was for gnome2/gnome3 i got scared so i didn't run that, BUT it gave me an idea (Which i came acros in the past)that idea was this command 'sudo gconftool --recursive-unset /apps/compiz-1' and this 'sudo gconftool --recursive-unset /apps/compizconfig-1' i rebooted and it worked perfectly. jeej :) –  blade19899 Apr 18 '12 at 20:19

I got unity working again by running these commands in the gnome-terminal and rebooting

Alternatively - CTRL+ALT+F1 to move to TTY1, login and perform the following:

quick-note: all your compiz settings will be reset!

sudo gconftool --recursive-unset /apps/compiz-1
sudo gconftool --recursive-unset /apps/compizconfig-1

If Panel and unity both disappeared you can get it back by typing below command in terminal

unity --reset

I guess this will help you.
