启用声音或读取 DVD 时出现
启用声音或读取 DVD 时出现拒绝访问
的错误
把你的用户加入 optical 和 audio 组。
# gpasswd -a johndoe optical # gpasswd -a johndoe audio
注销，然后使用普通用户登入（如，johndoe），这样刚才作出的组的修改就可以生效了。
如果你有 DVD 驱动器，你可能要为你真实的 DVD 驱动器创建一个 /dev/dvd 的符号链接。
例如，如果你使用 udev 而 DVD 驱动器又是 /dev/hdc 的话，你就可以使用 root 用户进行如下步骤：
# cat >>/etc/udev/rules.d/00.rules <<EOF > KERNEL="hdc", NAME="hdc", SYMLINK="dvd" > EOF # /etc/start_udev # mount /dev/pts # mount /dev/shm
