    Unhappy HELP! "Desktop effects could not be enabled" after upgrading to Ubuntu 10.10

    The desktop visual effect cannot be activated after I upgraded my Ubuntu 10.04 to 10.10. No matter "Normal", "Extra" or "Custom" option I selected in Visual Effects tab of the Appearance Preferences dialog box, the "can not be enabled" warning shows up. But I can enabled the Extra desktop visual effect under Ubuntu 10.04.
    My video card is nVidia m105, and my laptop is Thinkpad SL400. I tried to add my user account to the "gdm", "video" etc, but I got the same error message.
    So I came here to ask for your help.

    Also, I think I've updated the video driver to the latest version ("nvidia-current") using command "sudo apt-get update & sudo apt-get upgrade". I also installed the compiz using "sudo apt-get install compiz-*". But it seemed that was not working.

    Try going to the hardware center (Sys -> Admin -> Hardware), then remove the Nvidia driver, reboot and activate the driver again.

    Thanks for your reply. I already did this before I went here, but that didn't help.

    Re: HELP! "Desktop effects could not be enabled" after upgrade to Ubuntu 10.10

    Hello,

    I too reached this point. Then I went to Ubuntu Tweak and enabled x Updates stable. It gave me 5 nVidiia driver updates which I installed. Alas, to not avail. In a related issue, even though additional drivers tells me it is installed and activated, extras won't work in visual effects. Is this one of those just waits?
    Thanks, Richard

    Yes, I also enabled the x-updates source list in Ubuntu Tweak, but it gave me nothing new when I click Sync or Refresh button.

    Thank you. I was having the exact same problem. I figured it couldn't be the driver but was stumped to what it was. Here is the comment from above that fixes the issue.

    The post you refer to says the following:

    Please go to "Package Cleaner"->"Purge PPAs", purge the "Compiz PPA", it will fix this problem.

    Sorry for this newbish question.. but how do I "go to Package Cleaner" ??

    Thanks !

    I had this exact issue moving from 10.04 to 10.10 when it was released. I had tried purging all nvidia packages and re-installing nvidia-current, but what worked in the end was installing the latest driver off the nvidia site, not nvidia-current.
