use*_*870 5 display nvidia multiple-monitors hdmi external-monitor
我最近将笔记本电脑从 16.04 更新到了 Ubuntu 18.04。当我第一次尝试使用外接显示器时,一切正常,我将外接显示器设置为主显示器。然而,当我第二次尝试使用我的笔记本电脑时,外部显示器仅显示黑屏,即使它显示了连接的源(它显示一条文字“HDMI”,因为我通过 HDMI 连接显示器)。由于笔记本电脑已识别它并且自上次使用以来未修改设置,因此内置屏幕已关闭。
连接外部显示器时,xrandr会产生以下输出(请注意,我只能“盲目”运行它,因为每当连接第二个显示器时,两个屏幕都是黑色的):

我尝试了以下方法,但无济于事:
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash amdgpu.dc=0"到/etc/default/grub(请参阅此答案)
