Nvidia Removed Linux Driver Feature For Feature Parity With Windows 237

RemyBR writes "Softpedia points to a Nvidia Developer Zone forum post revealing that the company has removed a specific Linux feature as of the v310 drivers due to the Windows platform. A BaseMosaic user on Ubuntu 12.04 noticed a change in the number of displays that can be used simultaneously after upgrading from the v295 drivers to v310. Another user, apparently working for Nvidia, gave a very troubling answer: 'For feature parity between Windows and Linux we set BaseMosaic to 3 screens.'"

    Silly RMS and his free software. He is starting to look quite a bit more insightful, decades after he started his public campaign.

    I used that feature on a Geforce 2MX to try it out, a good while ago. No idea what you mean by "hacking" 3D support, you only had to press a hotkey to enable Stereo 3D in any game or app (with or without great results, but at least it's working or trying to). Five year laters I tried shutter glasses on Geforce 6/7 (too bad FSAA wasn't working, as I had to run at 640x480 or 800x600 on the old CRT to play with stereo).

    Anaglyph was really shit though, it fucks your color vision (after using it for a hour your eyes or brain compensate, if you look away from the screen and close one eye, one eye sees in red and the other in blue! to this day my right eye seems to see in a warm tint and the left eye in a cold one)

    What deal? The only deal would be between Nvidea and Microsoft, who I'm sure paid a princely sum to hide one of Windows' various deficiencies.

    Why do that, when you control the Windows logo rules?

    Windows must have a preferred status; features available to Windows users must surpass the list of features available to users of competing platforms; that is, as a condition of applying Windows logo certification to a qualifying hardware product, Hardware must have an experience or supported featureset on Windows that exceeds the user experience on any competing operating system.

    I think WHQL certification is mostly MS' way of pressuring component vendors to implement new features they want. For example; UEFI secure boot / OS signing, and preventing OSes such as Linux for booting, or providing TCPA / TCPM (Trusted Computing Platform Modules).

    But that's not all. there are plenty of features. Whatever MS requires or forbids will be extremely influential, as computer manufacturers Want to be able to advertise their product using the Windows Logo; and they are required to use only Windows logo certified components in their systems, so a hardware vendor not getting the stamp of approval on their product can be harmful to their business.

    MS will use their leverage to do what they think will improve the number of people buying their product --- that includes improving their user experience, or diminishing the user experience of old operating systems, or competing vendors' OS.

    For example: making new hardware no longer compatible with XP or Windows 7 would be a win for them, because it encourages more sales of Windows 8.

    The WHQL [microsoft.com] requirements are full of lists of features that must be supported and features that must not be supported by hardware.

    In the former category; they list supposed business justifications, and it's all about user experience.

    For the latter category; these are limitations of Windows, and the hardware is not allowed to have support for features outside of Windows' limitations.

    In the middle category; there are features hardware vendors must ask for permission to implement; that is probably the safest category for MS to use to pressure vendors --- just withhold permission, until they agree to 'off the record' conditions.
