是不是意味着 xf86-video-ati 没用了?

'''
Install the xf86-video-ati package. It provides the DDX driver for 2D acceleration and it pulls in mesa as a dependency, providing the DRI driver for 3D acceleration.

lshw的输出显示的是内核模块驱动信息
看看 cat /var/log/Xorg.0.log | grep radeon
还有没有这些信息

执行 cat /var/log/Xorg.0.log | grep radeon
什么都没有
离线
pacman -S xf86-video-ati
然后
cat /var/log/Xorg.0.log | grep radeon

看来还是有用的。
不过真没感觉出来有什么区别。

应该是跟2D加速有关,拖动窗口看cpu占用率

Unload不就是说用的驱动不是radeon吗?也许你的显卡比较新用的是xf86-video-amdgpu呢?

楼主的显卡是richland,本质上还是HD 6000系列,不是GCN,amdgpu不支持
