显卡：AMD Radeon HD 7570M


1,打开文件夹或运行其他程序都卡，右键菜单出来明显的慢，shell运行ls等也是卡一会才出来
2,top看资源的利用率貌似也不高
新手向请教各位大侠。谢谢
注：top中的java是运行了pycharm，但即使是关闭了pycharm也没有改善多少，还是会卡，点一会才反应。

补充一下：桌面环境是xfce，从登录时要求输入用户名登录就觉得卡顿，按tab键切到密码栏光标明显卡顿不流畅。

通常是 還沒安裝合適的驅動
把下面指令 複製 貼進終端機 執行
sudo lshw -numeric -class video
把結果直接 選取/複製 貼上來
不必擷圖

嗯，谢谢@poloshiao，结果如下:
public@debian:~$ sudo lshw -numeric -class video

你的電腦 有沒有 主板內建顯卡 ?

刚才走开了，谢谢@poloshiao，我试试，先定位到显卡问题就行，稍迟再报告。
最初也对显卡做了以下处理：
1,到hp的官网下载驱动，但安装后无法进行桌面环境
2,按照https://wiki.debian.org/ATIProprietary这里的方法，安装成功后，明显感到字体等变换，但对系统的卡顿并没有改善。
3,也关注的有关双显卡的问题，但貌似我的本本是独显，不大懂。lspci或lshw 没看到Intel HD Graphics等信息，VGA或者display只有ATI这个。
4,也到Debian HCL看了一下硬件驱动支持情况，水平有限，看得一头雾水。
