使用后，sudo lshw -c video我获得了有关系统中图形处理单元的信息，如下所示：
p@prikarsystem:~/Downloads$ sudo lshw -c video

显示Skylake GT2 [HD Graphics 520]来自Intel Corporation；这是VGA compatible controller我获得另一个选项，Display controller表示产品名称是Sun XT [Radeon HD 8670A/8670M/8690M / R5 M330 / M430 / Radeon 520 Mobile]。前者有physical_ID=2，后者，physical_ID=0。
我个人对图形处理单元及其与操作系统交互的细节没有太多经验，但我记得当我使用 Windows 时，视频规格还不错，但当我现在使用 Linux 时，在许多情况下，视频需要很长时间才能渲染。此外，我的系统上还有一张 amd-radeon 显卡的标签。
我想知道我实际拥有哪个物理设备，以便继续安装其驱动程序。解释和帮助将非常有益。
编辑：
使用相应规格的 linux-installable amd 驱动程序，我遇到了这个麻烦：
sudo apt install -f ./fglrx_15.200-0ubuntu1_amd64_ub_14.01.deb

我应该怎么做才能在这里安装我想要的东西？
