xset 为什么报错？

dacheng

我的命令及错误信息：
$ xset +fp /usr/share/fonts/truetype/msfont/
xset:  bad font path element (#76), possible causes are:
    Directory does not exist or has wrong permissions
    Directory missing fonts.dir
    Incorrect font server address or syntax

我的xorg.conf中的字体路径：
Section "Files"
        FontPath        "/usr/share/fonts/truetype/msfont"
        FontPath        "/usr/share/fonts/truetype/ttf-bitstream-vera"
        FontPath        "/usr/share/fonts/X11/misc"
        FontPath        "/usr/X11R6/lib/X11/fonts/misc"
        FontPath        "/usr/share/fonts/X11/cyrillic"
        FontPath        "/usr/X11R6/lib/X11/fonts/cyrillic"
        FontPath        "/usr/share/fonts/X11/100dpi/:unscaled"
        FontPath        "/usr/X11R6/lib/X11/fonts/100dpi/:unscaled"
        FontPath        "/usr/share/fonts/X11/75dpi/:unscaled"
        FontPath        "/usr/X11R6/lib/X11/fonts/75dpi/:unscaled"
        FontPath        "/usr/share/fonts/X11/Type1"
        FontPath        "/usr/X11R6/lib/X11/fonts/Type1"
        FontPath        "/usr/share/fonts/X11/100dpi"
        FontPath        "/usr/X11R6/lib/X11/fonts/100dpi"
        FontPath        "/usr/share/fonts/X11/75dpi"
        FontPath        "/usr/X11R6/lib/X11/fonts/75dpi"
        # path to defoma fonts
        FontPath        "/var/lib/defoma/x-ttcidfont-conf.d/dirs/TrueType"
EndSection

xset q中的相关输出：
Font Path:
  /usr/share/fonts/X11/misc,/usr/share/fonts/X11/100dpi/:unscaled,/usr/share/fonts/X11/75dpi/:unscaled,/usr/share/fonts/X11/Type1,/usr/share/fonts/X11/100dpi,/usr/share/fonts/X11/75dpi,/var/lib/defoma/x-ttcidfont-conf.d/dirs/TrueType

我的问题有两个：
为什么xset +fp命令出错？
为什么xset q中找不到/usr/share/fonts/truetype/msfont目录？
