Metamodes/Twinview depending on connected displays
 
Hi all,

I'm using my notebook either in a docking station with two connected LCDs (DFP-2 and DFP-3) or without the dock, ie. only with the internal display. So I'd like to have a twinview configuration that selects the two external displays if they are connected, or reverts to just the internal display (DFP-0) if they are not. I tried the setting
Code:

Option        "metamodes" "DFP-2: nvidia-auto-select +0+0, DFP-3: nvidia-auto-select +1920+0; DFP-0: nvidia-auto-select +0+0"
but it did not work: When the notebook is in the dock, I get the following output:
Code:

[  2815.163] (--) NVIDIA(0): Connected display device(s) on NVS 4200M at PCI:1:0:0

[  2815.736] (II) NVIDIA(0):    "DFP-2:nvidia-auto-select+0+0,DFP-3:nvidia-auto-select+1920+0"

With the last line, I'd assume that the two external displays should be in use, but DFP-2 is on position +0+0 (ok so far) and DFP-0 (ie the internal display instead of the second external LCD on DFP-3) is on position +1920+0, with DFP-3 disabled.

If the book is not in the dock, I get the following output:
Code:

[  3071.743] (II) NVIDIA(0):    "DFP-2:nvidia-auto-select+0+0,DFP-3:nvidia-auto-select+1920+0"

and, as I want, only the internal display is active.

Interestingly, CRT-0 always shows as connected even though it is not, neither with nor without the dock.

It would be great if anyone could point me towards what is wrong here... :)

BTW: An additional bonus would be if there were a third option for presentations in which the driver automatically cloned the internal display to CRT-0 if a CRT is connected :).

EDIT: Driver version is 280.13 on Ubuntu 11.10 x86_64.

Thanks!

I'm also experiencing the same problem with any driver after 275.09.07. The internal LCD display is recognized (DFP-0), as is the external VGA display. However, the external LCD (DFP-1) is recognized, but removed from the list of valid displays.

Where do I file a bug report?
