After installing new kernel update unity is not loading. Just blank screen without Unity panel. I have tried to delete Unity and Compiz config files, and to reinstall Unity, but there is no result. I also tried to boot with older kernel, but there is the same situation with unity. If in terminal (Ctrl+Alt+F1) try to run unity command, then will be message

 WARNING: no DISPLAY variable set, setting it to :0

I also checked if the video driver installed by runing lshw -c video, and the driver was mentioned there. How to solve this problem? Maybe I need to reinstall video driver (but I don't know how to reinstall built-in driver for my Intel HD Graphics 4000), or maybe something wrong with xorg...

Open the console by the following keys:

Then do the following:

Use this to Remove/Uninstall Compiz Unity:

sudo apt-get remove compizconfig-settings-manager
sudo apt-get remove compiz-fusion-plugins-extra
sudo apt-get remove compiz-plugins-extra

Then to Re-install Compiz Unity use:

sudo apt-get install ubuntu-desktop
sudo apt-get install ubuntu-desktop-2d
sudo apt-get install compizconfig-settings-manager
sudo apt-get install xserver-xgl
sudo apt-get install emerald
sudo apt-get install compiz-fusion-plugins-extra
sudo apt-get install git compiz-plugins-extra
