I have a system:

* Antec Sonata III 500 case with power supply
* Intel DQ67SWB3 motherboard
* Intel Core i7-2600S processor
* Corsair CMV8GX3M2A1333C9 memory 2 @ 4 GB DDR3 1333 MHz matched pair
* Intel SSDSC2CW060A310 solid state drive -- 520 series, 60 GB, SATA 3
* Seagate ST3000DM001 hard drive -- 3 TB, 7200 RPM, 64 MB, SATA 3
* Pioneer BDR-2206B5PK Blu-ray drive -- RW, 12x, SATA
* StarTech DVIVGAMFBK DVI to VGA adapter connected to DVI-I port
* Nokia 445XiPlus monitor connected to StarTech DVIVGAMFBK adapter
* StarTech DP2VGA2 Display Port to VGA adapter connected to DisplayPort port
* Nokia 445Xi monitor connected to StarTech DP2VGA2 adapter

The goal is to get both monitors working at maximum resolution and 
refresh rate in extended desktop mode.

Here are the BIOS -> Configuration -> Video settings:

     Integrated Graphics Device                            Always Enable
     IGD DVMT Memory                                        Maximum DVMT
     Primary Video Adapter                            Int Graphics (IGD)
     IGD Primary Video Port                          DVI-I (Blue) Analog
     IGD Secondary Video Port                                DisplayPort
     No Video Detected Error Beeps                                Enable

I have installed Debian testing (Wheezy) amd64 and have all current updates:

The primary monitor ("Nokia445XiPlus" on VGA1) looks good.  :-)

The secondary monitor ("Nokia445Xi" on DP2) is repeatedly resizing 
horizontally -- the right edge of the screen creeps in ~0.5" in ~3.6 
seconds, the screen flashes and resizes to full size, and then the 
process repeats.  :-(

Any suggestions?
