If you are like me, you probably installed Flash player from the repository, expecting it to work properly. Well, that just isn't the case. For instance, on YouTube or Hulu videos, I wasn't able to push the buttons without first right clicking, then left clicking twice. Weird, huh?

Here's how to get the Adobe Flash 64 bit Alpha for Linux working in Ubuntu 9.10 Karmic Koala.

First, close Firefox. Next, uninstall the following packages if you have them installed:

sudo apt-get remove flashplugin-installer flashplugin-nonfree nspluginwrapper
