I would like to know if a DualHead2GO would work in Linux, to have two external screens attached to it and to the VGA/DVI of my laptop:

http://www.matrox.com/graphics/en/products/gxm/dh2go/

The model number below:

18ea:0004 Matrox Graphics

According to the other ids I found on http://www.linux-usb.org/usb.ids , my model is probably a DualHead2Go Digital Edition:

18ea  Matrox Graphics, Inc.
    0002  DualHead2Go [Analog Edition]
    0004  TripleHead2Go [Digital Edition]

maybe this thread will give you some ideas - ubuntuforums.org/showthread.php?t=1744124 –  fossfreedom Aug 2 '11 at 11:40
    
Is this something specific to Matrox hardware or generic to many manufacturers? –  213441265152351 Aug 3 '11 at 19:31

1 Answer 1

As Fossfreedom pointed out, Cyclops_ got it to work (see) by updating the firmware and changing the settings under Windows.
