I agree that Nvidia should explain more precisely the reason why the feature was removed from Linux driver. Only saying “for parity with Windows” isn’t enough as there are many possible assumptions:
- Quality Assurance : feature to support 4+ screens not fully and really tested on Linux, waiting for more benchmarks and returns
- There have been problems and bug reports for this option in Linux so it is deactivated for the moment until correction.
- It is easier to maintain the code if most of it is identical both in Linux and Windows. But that’s not logical : if it was the case, this feature wouldn’t have been all implemented in Linux first.
- There is a commercial agreement between Nvidia and Microsoft, ensuring that the performances and features of drivers can not be better than those in Windows in any other Operating System.
Such agreement could exist (we already saw worse with MS), but Nvidia would never admit it, and again if it was, why having put this feature in BaseMosaic v295 ?
Is this situation provisional (and will be reintroduced soon on a next version of Linux driver) or definitive ?
So that’s why Nvidia should tell us with more details the justification of remove and not only “This is expected behavior for latest drivers. For feature parity between Windows and Linux we set BaseMosaic to 3 screens on GeForce.”
For the moment, I tried to ask Nvidia on Twitter - https://twitter.com/valeryan24/status/386627085919207424 and https://twitter.com/valeryan24/status/387204503411232768 - on the French Nvidia Facebook official page : no answer. There is also a discussion here - http://hardware.slashdot.org/story/13/10/05/0021237/nvidia-removed-linux-driver-feature-for-feature-parity-with-windows - and for french readers interested : http://linuxfr.org/users/valeryan_24/journaux/hypocrisie-de-nvidia-envers-le-libre-le-pilote-graphique-linux-volontairement-degrade
