ubuntu nvidia显卡切换

笔记本是双显卡 intel+navida

刚开始时 sudo ubuntu-drivers autoinstall 装好驱动，外置显示器显示正常，后来重启后死活不显示

查了一天的资料，终于找到答案了

原因是切换过 intel 显卡，变成节能模式，hdmi 接口就检测不了外置显示器，要注释掉 nvidia-drm modeset

sudo nano /lib/modprobe.d/nvidia-kms.conf

# Set value to 0 to disable modesetting
# options nvidia-drm modeset=1
