    Stop altering the root window pixmap to avoid X crash (bug #7442).
    
    Altering the back pixmap makes X segfault, sometimes on startup
    of xfdesktop, all the time during logout. Not the best solution
    to fix it this way, but the background is still shown when
    xfdesktop is running, so not a big issue.
