    Did you disable composite?<br>
    <br>
    Run sudo nvidia-xconfig --no-composite <br>
    OR, add this to /etc/X11/xorg.conf or a file in /etc/xorg.conf.d:<br>
    Create file /usr/share/X11/xorg.conf.dG/55-mythtv.conf, or 
    /etc/X11/xorg.conf <br>
    Section "Extensions"<br>
        Option             "Composite" "Disable"<br>
    EndSection<br>
    NOTE This is incompatible with unity desktop in 13.04 and later<br>
    You will have to install and use xfce desktop manager instead of
    unity<br>
