Mplayer在root身份下使用正常，普通用户下却无法使用！

秦武扬

用root用户登录后可以正常使用！但是普通用户就不行，连在普通用户下用sudo都不行！这个问题太邪门了，请Debian高手指教！

这中问题，我不是第一次碰上，但从来没有解决过，最后都只能通过重装Debian来解决，这次我不想再重装了！

我在好多地方求助过这个问题，但一直无人能帮我！

root以后startx了？

估计是你修改过mplayer的权限吧。

ls -l一下看看是什么样的。

试试添加用户到video组，重新登录一次

秦武扬

qwy@redforce:~$ ls -l /usr/bin/gmplayer
lrwxrwxrwx 1 root root 7 10-05 15:19 /usr/bin/gmplayer -> mplayer
qwy@redforce:~$ ls -l /usr/bin/mplayer
-rwxr-xr-x 1 root root 4367580 10-01 02:52 /usr/bin/mplayer
qwy@redforce:~$


这是ls的结果！

我确实在xorg.conf坏掉时，用root登录后startx过！问题莫非出在这个步骤上？！

ls的结果跟我的看起来一样啊，不过我的是ubuntu，应该没关系的。
你在普通用户下输入 mplayer 提示什么？

mplayer可以运行
好像是你 mount 的目录权限不够，不能读取，你 mount 时把权限改一下

例子：
在/etc/fstab   中加入  
  /dev/hda6   /mnt/ntfs   ntfs   defaults,umask=0222,gid=adm   0   0  
  其中umask是指有什么权限，0222   =   -r-xr-xr-x     或者   777   =   -rwxrwxrwx  
  gid是指用户组，   重启后就可以了。

我装过几次了，从来也没碰到楼主的这种情况啊？

我的系统里没有ntfs分区，我都是里斯格式的文件系统！

看看你存mp3的目录和文件的权限是不是正确
