I've researched this for the better part of the day and I can't seem to find the cure. I can no longer autohide the launcher and then get it to reappear again using the mouse. I know it's there as I catch a glimpse of the animation when minimizing windows but I can no longer place the mouse on the left edge or alternately the left corner and get it to reappear. I can use the super key to bring it up. A recent upgrade included a new Nvidia update which doesn't appear to have changed anything. I have recently installed Docky and Wine. I've turned off Docky to see if that was affecting things but that doesn't appear to be the case. I have the Unity plugin checked under Compiz and I've lowered the reveals and sensitivities to no avail. I have tried changing these settings in My Unity and Ubuntu Tweak. I've re-installed all the packages under the package manager. I'm not sure what to try next. Any suggestions? Wanna kill these ads? We can help!
