Ever since I installed Ubuntu on my computer, I have had issues with Flash objects. Half of the time, I was unable to click on certain parts of Flash objects, like the video controls in some YouTube videos, for example. For the longest time, I thought that the problem was due to the fact that the 64-bit Adobe Flash plugin is in it’s alpha stages, but recently I discovered the real culprit.
It turns out, Compiz interferes with how the system gets information from my mouse, causing the failed clicks. Simple solution is to turn off Compiz, and the problem disappears.
For me, this came with a new problem. Gnome Do‘s Docky requires compositing in order to work, so without Compiz enabled, I was left without a dock (and I like my dock). As uninformed as I was, I didn’t know that Gnome’s own Metacity had a compositing manager bundled with it, so I enabled that and I saw my dock once more. Just to be safe, I tested that Flash objects still worked. They did.
So, how can you go about disabling Compiz and enabling Metacity’s compositing manager? Read on.
- Click on System->Preferences->Appearance and then navigate to the Visual Effects tab.
- Select ‘None’ and close the window.
- Open up a terminal window and run the command:
- In the left tree pane, navigate to apps->metacity->general and find compositing_manager in the list on the right.
- Enable the compositing_manager option and close the window.
- Restart the X Server or just log off and log back for changes to take effect.
