[SOLVED] Duplicate screen to VGA monitor through HDMI

Hi all !

Here is my hardware configuration:

PC: I have a HP laptop (Envy 15, HD Intel graphics + NVIDIA), with a single HDMI port.
I'm using Intel graphics all the time, and I have access to my nvidia card sometimes through bumblebee/optirun.
Adapter: I've bought a simple (but expensive) adapter HDMI -> VGA to connect my monitor to my laptop
Monitor: I've a simple neovo VGA monitor.

Here is my actual outputs:

I'm using GNOME, and once all connected (and monitor turned ON), I've only my laptop screen on the GNOME settings.
So I've seen to use xrandr:

$ xrandr
Screen 0: minimum 8 x 8, current 1366 x 768, maximum 32767 x 32767
eDP1 connected primary 1366x768+0+0 (normal left inverted right x axis y axis) 344mm x 194mm
   1366x768      59.99*+  39.94  
   1280x720      60.00  
   1024x768      60.00  
   1024x576      60.00  
   960x540       60.00  
   800x600       60.32    56.25  
   864x486       60.00  
   640x480       59.94  
   720x405       60.00  
   680x384       60.00  
   640x360       60.00  
HDMI1 disconnected (normal left inverted right x axis y axis)
VGA1 disconnected (normal left inverted right x axis y axis)
VIRTUAL1 disconnected (normal left inverted right x axis y axis)

And then:

$ xrandr --output HDMI1 --auto                         

Intentionally left blank

I mean, I've no errors, no success messages, nothing. But my monitor is still black with "no signal" message.

I'm open to all ideas.

Re: [SOLVED] Duplicate screen to VGA monitor through HDMI

After many reboots, nothing.

Then I've booted over Windows7 or Ubuntu, also nothing.

But now it works, no reason
