    Default 3D effects no longer working

    I did an update to KDE 4.5 recently, and afterwards noticed that 3D effects were no longer enabled. When I try to enable them from desktop settings, I get a pop up in the panel that says another application is preventing compositing (or something like that).

    I have the nvidia 256.53 drivers installed and 'glxinfo' says direct rendering is on. I'm also using X server 1.9, but compositing was working with the new X server before I did the update to 4.5.

    Anyone else getting this or know a fix?

    Are you using KWIN?
    And is that the setting you have in Default Applications > Window Manager?

    says another application is preventing compositing (or something like that).

    Yes, I'm using KWin. I'll post the exact message later when I'm in front of my Linux box.

    Looks like you need to reinstall the NVIDIA driver. Some X update/upgrade will have damaged it's install, or the driver module from the repos does not have the module for the running new kernel.

    I reinstalled the nvidia driver this morning after I updated X server, which was about the fourth time I've installed it lately while trouble shooting this problem.

    The exact message I get when trying to enable compositing is this:

    Desktop effects have been suspended by another application. You can resume using shift > alt > F12
    Here are some screen shots:

    I had the exact same issue a few days ago on my 11.2 box, what bugged me the most out of it is that there is no log to be found where you at least can find which other application. It was enough to reinstall the nvidia drivers (manually), it happened after this set of updates:

    Code:
    rpm -qa --last | more

    as I said I did the nvidia update manually, it does an uninstall of the previous install which I am not sure the rpm does, and that fixed it.

    So now if you go back to your normal account
    Do a console login and rename and backup .kde4 - like this:

    Code:
    mv .kde4 .kde4-backup
    then switch to su -
    and type reboot

    At the login screen now, remember to make sure the session is selected to kde and login
