my Ubuntu 13.04 64 bit broken unity and compiz after installing nvidia driver, i've tried the below command:

dconf reset -f /org/compiz/ 
unity --reset-icons &disown

but i get:

compiz (core) - Info: Loading plugin: core
compiz (core) - info: Starting plugin: core
unity-panel-service: no process found
compiz (core) - Error: Another window manager is already running on screen: 0
compiz (core) - Info: Stoping plugin: core

i found a page here saying that reboot if it doesn't work right away. same broken unity after reboot.

You need to make nvidia config:

sudo nvidia-xconfig

Then restart your login manager.

sudo restart lightdm

If it does not help, try to load nvidia kernel module manually:

sudo modprobe nvidia

And even if it does not help, you have to blacklist nouveau module:

echo "blacklist nouveau" | sudo tee -a /etc/modprobe.d/blacklist.conf

Then restart and your problem should disappear. If not, check if your card is supported by the driver.
