I have a LUBUNTU 16.04 system, and I've been trying to make chromium browser go fullscreen on a dual display setup without success. It just goes fullscreen on a single display.

It must also be done automatically on startup. Can't login to manage this every day.

I've been fiddling with XRandR and Xinerama but I'm no expert here.

Also tried several options in the chromium command itself:

--window-position=0,0 --window-size=3840,1080 --kiosk

XRandR output: XRandR output

The hardware I'm using is an Intel Nuc with an Intel Core i3-6100U CPU. Integrated graphics, which I think it's HD 520. The display setup is just two 1920x1080 HDMI displays on a frame. I leave the desktop as is (not rotated). Something like this:

So at this point I'm not sure if this is a chromium related problem or I just didn't get my display setup correctly. Is this at all possible to achieve?

From experience I know that plasma KDE is capable of this through a KWin script. Just pressing F11 makes the target window go fullscreen on all activated displays. However, this system is part of a network of thousands of players running LUBUNTU which update and configure themselves automatically, so changing the DE would be the last resort.

Thanks in advance

For others who might be reading this now years later,

xrandr --setmonitor virt auto HDMI-1,HDMI-2

Could do the trick.It would create a virtual monitor with the resolution of both screens put together.
