实验室的台式机，一个vga接口，一个HDMI接口，开机和关机时两台显示器都出现deepin标志，但是进入桌面之后只有vga的显示器可以成功显示，切换win10可以双屏所以排除硬件原因，xrandr -q之后显示只有vga的是connected

然后listproviders有两个


Providers: number : 2
Provider 0: id: 0x77 cap: 0xf, Source Output, Sink Output, Source Offload, Sink Offload crtcs: 3 outputs: 5 associated providers: 0 name:modesetting
Provider 1: id: 0x43 cap: 0xf, Source Output, Sink Output, Source Offload, Sink Offload crtcs: 2 outputs: 2 associated providers: 0 name:OLAND @ pci:0000:01:00.0


按照网上的方法setprovideroutputsource之后就显示Could not find provider with name
显卡是Intel集显和amd独显
