I have a laptop, which has two display output (+the built-in display)
I can connect a single external monitor to in the VGA output or the HDMI output and it works. Gnome Display detects the external monitor and I can set to extend the Desktop.
However when I try to connect two external monitors, one to VGA and one to HDMI. I am left with only two displays, out of the three at a time. (Either two external and no built-in output (blank), or one external and one built-in (second monitor blank).
Is there a way to force the three displays to work when I connect the two monitors?
The laptop is a Dell Inspiron 17R, http://www.dell.com/en-us/shop/cty/inspiron-17r-laptop/spd/inspiron-17r-5721
