So you were trying to customize your Ubuntu 14.04 desktop but messed it up to end up with no Unity, no Launcher and no Dash? Don’t panic, there is a solution for this issue.
Fix no Unity, no Launcher, no Dash in Ubuntu 14.04 and 14.10
At login time, use Ctrl+Alt+F1 to access the command line interface. You will have to use your username and password here. Once logged in, use the following commands:
sudo apt-get update sudo apt-get install --reinstall ubuntu-desktop sudo apt-get install unity sudo shutdown -r now
Hope this fixes the issue with Ubuntu 14.04 and Ubuntu 14.10.
If the above solution did not work for you, try removing everything from config using the command below:
rm -rf ~/.config
This will reset everything and your Ubuntu system will resemble to the looks of a fresh install. Installed applications will be untouched.
If even that did not work for you, there is another trick which was used in Ubuntu 12.10. Give it a try of you want to.
Fix no Unity, no Launcher, no Dash in Ubuntu 12.10
I was installing Ubuntu 12.10 on my friend’s laptop the other day when i encountered this strange scenario. After the fresh install when I boot in to Ubuntu, there was no Unity, no side launcher, no dash, nothing. All it had was just the default wallpaper of Ubuntu 12.10:
Clearly something was broken. I tried the good old technique to reset Unity and Compiz in Ubuntu, did not work. After looking for hours in forum, I came up with this awesome one liner solution.
Use Ctrl+Alt+T to open the terminal. Now use the following command in the terminal:
rm -rf .compiz-1
And that is it. No need to do anything else. You will have Unity back again. Cheers :)
