There is no unity dash or nothing after I updated my system last night. System Information : Distributor ID: Ubuntu Description: Ubuntu 14.04 LTS Release: 14.04 Codename: trusty Kernel Version : 3.13.0-27-generic And I have NVIDIA drivers 331.67 installed. I have also tried to fix this by following the advice from this post : Unity doesn't load, no Launcher, no Dash appears But no luck. In the CompizConfig Settings Manager, Ubuntu Unity Plugins is enabled, but no unity, even after a reboot. If there is a way to retrieve the list of packages which got updated the last time, please tell me so that I can post them here.
