I suddenly had my unity crashed. Dashboard and launcher have suddenly stopped functioning.
I saw the following thread: Unity doesn't load, no Launcher, no Dash appears
However when executing the command
DISPLAY=:0 ccsm &
I am receiving the following error:
"*ImportError: /usr/lib/x86_64-linux-gnu/libharfbuzz.so.0: undefined symbol: FT_Reference_Face*"
I also tried to reinstall unity by running
sudo apt-get install --reinstall ubuntu-desktop
sudo apt-get install --reinstall unity
but the same issues appear.
Any ideas on what is the problem?
