I just updated to the latest version (11.04) yesterday, and ever since then, the system has been really choppy.

I used to have 10.10 installed, and that was running smooth.

Anyone also experiencing this? Any fixes?

I'm only running Chrome and Netbeans...

  1. Install CompizConfig SettingsManager

    sudo apt-get install compizconfig-settings-manager

  2. Click on the Composite tab, and un-check Detect refresh rate.

I had same problem, but, however, in my case adjusting compiz settings didn't help a lot.

I also had ATI drivers installed. Then I noticed ATI had JUST released new ones, which are said to have much better supprot for the latest X and Unity. However, ATI released them too late, and they failed to get into Ubuntu repositories.

What I reccoment you is to uninstall the ATI driver (fglrx) Ubuntu installed for you, and get the newest one from the ATI's site: http://support.amd.com/us/gpudownload/Pages/index.aspx

In my case this provided incredible improvement of overall performance. I hope it will help you too!
