I use ubuntu since 2008, i never install a software antivirus, I do not know if there exist. Challenge you to stand up for 3 years without antivirus in windows. put to me a few examples of viruses on Linux and then .... ask yourself why the most famous viruses throughout history have always been struck by windows and linux.
it is ubuntu 10.04, I installed the repository to add some news outlets from ubuntu 10.10.
What version of driver you have installed and Compiz?
Look in the options and the plugin system as it sees it'll much better ... What I have now is nothing compared to what you see in the video.
Thanks for watching
