I have a pc connected to my tv, I would like to disable the laptop monitor while it's connected.To see all the connected monitors I run this tail /sys/class/drm/*/status and I get:==> /sys/class/drm/card0-DP-1/status <==disconnected==> /sys/class/drm/card0-LVDS-1/status <==connected==> /sys/class/drm/card0-VGA-1/status <==connectedNow when I run xrandr --output LVDS-1 --offAll screens go black, and I can't even find the command to get them on so I just restart.I would like just to just blank the laptop monitor.After that I would add it too boot. But that should not be a problem.Any suggestions?p.s - when they are on I get a duplicate setting on them.I have an xorg.conf file'Section Device  Identifier  Device0  Driver      modesetting  VendorName  INTEL CorporationEndSectionSection Screen  Identifier  Screen0  Device      Device0  Monitor     VGA-1  DefaultDepth  24  SubSection Display    Depth       24    Modes     1920x1080@59.94p 1920x1080@24p 1920x1080@60p  EndSubSectionEndSectionSection Monitor  Identifier  VGA-1  HorizSync   14.0 - 70.0  VertRefresh 24.0 - 62.0#  Option      DPMS true  Modeline    1920x1080@24p     74.230 1920 2560 2604 2752 1080 1084 1089 1125 +hsync +vsync  Modeline    1920x1080@50p    148.500 1920 2448 2492 2640 1080 1084 1089 1125 +hsync +vsync  Modeline    1920x1080@59.94p 148.352 1920 1960 2016 2200 1080 1082 1088 1125 +hsync +vsync  Modeline    1920x1080@60p    148.500 1920 2008 2056 2200 1080 1084 1089 1125 +hsync +vsyncEndSectionSection Extensions  # fixes tearing  Option      Composite           DisableEndSection
