安装了amd开源驱动，如何才能启动呢

因为开源的驱动可以双显卡切换，所以选择了amd的开源驱动，参考wiki里面ati闭源驱动的安装https://wiki.archlinux.org/index.php/ATI_(%E7%AE%80%E4%BD%93%E4%B8%AD%E6%96%87)
安装xf86-video-ati,lib32-mesa-libgl mesa-vdpau lib32-mesa-vdpau
因为系统中没有这个文件/etc/X11/xorg.conf.d/20-radeon.conf，然后手动添加。
在/etc/mkinitcpio.conf，加入了MODULES="radeon"
# mkinitcpio -p linux

在wiki后面的关于设置的内容没有进行，系统重启还是使用的intel集显。请问：
如何启用amd显卡并在intel与amd双显卡之间切换

Re: 安装了amd开源驱动，如何才能启动呢

我没有intel cpu，
https://wiki.archlinux.org/index.php/AT … e_Graphics
https://help.ubuntu.com/community/Hybri … ch_the_GPU
这个试下，试完记得反馈下详细步骤，也许我以后也会用到
