Comment 3 for bug 1019023

The launcher script "/usr/lib/fglrx/bin/amdxdg-su" tests for various desktop environments to determine which sudo front-end to use.

case "$DE" in
    kde)
    su_kde

    exit_failure_operation_impossible "no graphical method available for invoking '$cmd' as '$user'"
    ;;
