    The model you're linked doesn't specify compatibility, though it does list its inputs:
    VGA / SVGA / XVGA Input: Scaled to SVGA (800 x 600)

    It 'might' work out of the box like a plug and play monitor but it also may not.

    The best way to check on Linux support is to contact the manufacturer of the devices you are looking at.

    Custom drivers can be made for linux but it is easier for people to do so with the cooperation of the original developers.

    There are, now that small LCDs have gotten cheap, numerous "display glasses" type products that toss an LCD in front of each eye and have some sort of video input(generally VGA or composite, sometimes both or other). Basic VGA-in display glasses should work exactly like any other monitor on virtually anything. No guarantee that the EDID isn't complete nonsense; but it should basically work.

    Any sort of OMG Stereoscopic Vision! drivers, though, will probably be useless in Linux. Those guys [prnewswire.com] claim to support stereoscopic shutter glasses under certain conditions; but seem to be aiming at the Real Serious Workstation market. If you can deal with normal, non-3D glasses, you should have no problems, 3D, possibly not so much.

    VR goggles are nothing more than miniature displays that are mounted on eyeglass frames, so I doubt there'd be a compatibility issue, per se. You may have to get your hands deep into the xwindows config files to fine tune things, though, because they likely won't be set up already.

      Normally dual displays just expand the size of the viewing area from one camera point. To have stereoscopic support 3D images need to have 2 viewing cameras setup, at a slightly different offset; viewing the same object from different angles.

      So a dual monitor desktop still has just one perspective, for 3D you need 2.

      Its a lot easier to do this with dual displays, as you only really need to modify the camera config in openGL, or your F/X API of choice (of course this is best done in the software itself or v

        Someone, somewhere is doing it wrong. VR goggles should work fine if you're farsighted. The actual location of the display isn't what matters, it's the distance your eyes need to focus to in order to bring the image into focus. With proper image separation, you should be able to focus on "distant" objects in VR goggles.

        On the other hand, often, focusing on any object for someone with normal eyesight using VR goggles is challenging.

    The Clemson VR lab uses (or used, at least) Linux workstations to run provide input to their VR goggles. Compatibility shouldn't be an issue, but you basically have to provide content yourself -- things won't automatically be cool. We didn't even use any kind of support in the drivers -- the goggles were two 640x480 screens, but were treated as a single 1280x480 screen. We just used OpenGL to draw two versions of our scenes from slightly different positions and presented them side-by-side so that they mapped properly onto the goggles.

In case you're wondering, the $60 option is an NTSC TV fed into a dimly lit monoscopic visor, while for $40,000 you get an amazing 1280x1024 digital LCD stereoscopic per eye at 90Hz. Nowhere in that range is a device that you can wear to use a GUI or a CLI interface for more than about 40 minutes. Even if your eyeball's diopter requirements are calibrated very carefully, even if your visual acuity is excellent, even if the contrast is good and the font sizes are large and beautiful, you will just not be well-served by reading text on a near-range display for more time than that.
