With my Asus Zenbook UX31E (Intel HD Graphics 3000) when I plug an HDMI device in and run xrandr everything is fine and both laptop and external HDMI monitor work. However, when I disconnect the HDMI device and run xrandr again it gives the following errors and both screens go off. [jamie at jamie-laptop ~]$ xrandr --output eDP1 --auto --output HDMI1 --auto --above eDP1 xrandr: Configure crtc 0 failed X Error of failed request: BadMatch (invalid parameter attributes) Major opcode of failed request: 150 (RANDR) Minor opcode of failed request: 21 (RRSetCrtcConfig) Serial number of failed request: 38 Current serial number in output stream: 38 [jamie at jamie-laptop ~]$ xrandr -q Screen 0: minimum 320 x 200, current 1920 x 1980, maximum 8192 x 8192 eDP1 connected (normal left inverted right x axis y axis) 1600x900 60.0 + 1024x768 60.0 800x600 60.3 56.2 640x480 59.9 VGA1 disconnected (normal left inverted right x axis y axis) HDMI1 disconnected (normal left inverted right x axis y axis) DP1 disconnected (normal left inverted right x axis y axis) When both are connected and working: [jamie at jamie-laptop ~]$ xrandr -q Screen 0: minimum 320 x 200, current 1920 x 1980, maximum 8192 x 8192 eDP1 connected 1600x900+0+1080 (normal left inverted right x axis y axis) 293mm x 164mm 1600x900 60.0*+ 1024x768 60.0 800x600 60.3 56.2 640x480 59.9 VGA1 disconnected (normal left inverted right x axis y axis) HDMI1 connected 1920x1080+0+0 (normal left inverted right x axis y axis) 475mm x 267mm 1920x1080 60.0*+ 1600x1200 60.0 1680x1050 60.0 1280x1024 60.0 1440x900 59.9 1280x960 60.0 1280x720 60.0 1024x768 60.0 800x600 60.3 640x480 60.0 720x400 70.1 DP1 disconnected (normal left inverted right x axis y axis)
Same behaviour on my UX32VD.
