  • Fix "usr/bin/Xvnc: undefined symbol: pixman_composite_trapezoids"

    This is one another error which appears while trying to restart vncserver services which came to me in CentOS 6.2.

    /usr/bin/Xvnc: symbol lookup error: /usr/bin/Xvnc: undefined symbol: pixman_composite_trapezoids

    /usr/bin/Xvnc: symbol lookup error: /usr/bin/Xvnc: undefined symbol: pixman_composite_trapezoids
    Make sure that the below mentioned package is installed and updated to the latest version available.

    # rpm -qa | grep pixman

    If the above packages are missing, install them using yum

    # yum install pixman pixman-devel

    Now try starting your vncserver services and let me know your success and failure rate.
