Intel Graphics and Dual Monitor

Hi all,

I'm trying to run dual monitors using the built in Intel Graphics in my motherboard. The Motherboard has 2 HDMI ports and 1 DP. I'm using both of the HDMI ports.

Here is the output from lspci regarding VGA controller:

00:02.0 VGA compatible controller: Intel Corporation Device 3e92 (prog-if 00 [VGA controller])
	Subsystem: ASRock Incorporation Device 3e92
	Flags: bus master, fast devsel, latency 0, IRQ 122
	Memory at de000000 (64-bit, non-prefetchable) [size=16M]
	Memory at c0000000 (64-bit, prefetchable) [size=256M]
	I/O ports at f000 [size=64]
	[virtual] Expansion ROM at 000c0000 [disabled] [size=128K]
	Capabilities: <access denied>
	Kernel driver in use: i915
	Kernel modules: i915

   720x400       70.08  
HDMI2 disconnected (normal left inverted right x axis y axis)

I have tried running the following commands without any success

xrandr --output HDMI1 --auto --output HDMI2 --same-as HDMI1
xrandr --output HDMI2 --auto

Re: Intel Graphics and Dual Monitor

Quick note: I have used both the HDMI ports before and it worked flawlessly. Just recently removed the second one to work on another computer. Now, when plugging it back in again, the second monitor is not detected.

Re: Intel Graphics and Dual Monitor

Hi again, this resolved itself by shutting down the computer completely (Reboot was not enough) and waiting a couple of minutes. At startup the second HDMI port was enabled again.
