我有一台 emachine W3105。AMD Sempron 3100+ 1.8 GHz 处理器 512 MB RAM 100 GB 硬盘 DVD±RW DL 驱动器
我用 Ubuntu 12.04 替换了 Windows XP 操作系统，但它无法检测到 DVD±RW DL 驱动器。我运行了 sudo lshw -C disk，结果如下。

在我看来，Ubuntu 操作系统检测到了 DVD 驱动器。这是否意味着我必须安装 AMD 的专有驱动程序？我也尝试了该mount命令，但得到了这个

我尝试了这个命令lspci -vvnn | grep GA，得到了这个，

这是我遇到的问题。我只想在驱动器中读取 CD 和 DVD？有人能帮忙吗？谢谢
