想要与第二台显示器共享我的屏幕，但是连接 HDMI 后没有任何反应。只是未检测到第二个监视器。我尝试执行命令
xrandr --listproviders
Providers: number : 2
Provider 0: id: 0x8d cap: 0x2, Sink Output crtcs: 3 outputs: 4 associated providers: 0 name:modesetting
Provider 1: id: 0x66 cap: 0x7, Source Output, Sink Output, Source Offload crtcs: 4 outputs: 3 associated providers: 0 name:nouveau
rafal@Precision:~$ xrandr --setprovideroutputsource 1 0
X Error of failed request: BadValue (integer parameter out of range for operation)
Major opcode of failed request: 140 (RANDR)
Minor opcode of failed request: 35 (RRSetProviderOutputSource)
Value in failed request: 0x8d
Serial number of failed request: 16
Current serial number in output stream: 17
我收到错误消息。我记得下面的命令一旦起作用，连接 HDMI 后，我就看到了第二台显示器，我可以打开它。
xrandr --setprovideroutputsource 1 0
我不知道我的系统现在发生了什么。我认为某些软件包可能会更新或升级，这导致今天没有检测到我的第二台显示器。然后从这个主题中给予帮助 Debian 9 未检测到 hdmi 端口中的显示器 但不是今天
我也尝试创建xorg.conf包含内容的文件
Section "Device"
Identifier "Intel"
Driver "intel"
# Option "AccelMethod" "uxa"
# Option "VSync" "false"
EndSection
我的 HDMI 显示器上只有白屏，但这只是一次。
