I did this, and this is the output:

I have no idea what all of it means, but hopefully someone else will be able to make sense of it.

Your laptop has 2 graphics chips:

An Intel Core Graphics chip, running and i915 driver.

And you have an ATI Radeon HD 5000M graphics chip. Running the fglrx_pci driver.

To verify this, list the modules (drivers) you are running:

Code:

lsmod

Does your laptop have two graphics ports? Perhaps a VGA (15 pin, blue) port and a white, multipin DVI port.

Not to scare you, but you may need to read this thread and start to understand the tweaking that may be required to get your combination to work.

This came from a simple google search: ubuntu dual display fglrx_pci

I typed lsmod in the terminal and this is what I came up with:

As for the graphics ports, I have a blue VGA and an HDMI port. Before I used the HDMI port to connect to the monitor in Windows.

And what is the model and native resolution of the Samsung display?

**elhancho** · December 10th, 2012

The model is the Samsung SyncMaster T260HD and the native resolution is 1080p 1920 x 1200 at 60 Hz.

I have an older version of that monitor, and I use dual-monitor all the time with my thinkpad. But I use a DVI port as my thinkpad does not have an HDMI out.

So in reading the mega-thread that I posted above, there are some limitations using the fglrx driver and the arrangement of your monitors.

I have 12.10 running on another machine, but I don't have dual monitors set up so I cannot help any more at this point. Others will have to chime in for the commands to use. There are several suggestions in the thread that I posted earlier.
