Nvidia Removed Linux Driver Feature Due to Windows

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.

According to the post, the Ubuntu user connected three displays using BaseMosaic, backed by Nvidia's v310 drivers and two GeForce GTX 560 Ti cards in SLI. But after configuring the xorg.conf file and adding the supposedly supported fourth display, only three monitors would light up.

What's interesting here is that Nvidia's proprietary Windows driver has features not found in the Linux drivers, but the company will remove specific Linux-only features for "parity." The comment indicates that the three-screen limit has nothing to do with a degradation of quality when using four screens, but a possible Microsoft request/demand.

Nvidia's driver documentation states that BaseMosaic can be used to extend a single X screen transparently across all of the available display outputs on each GPU.

Maybe for "parity" they can downgrade the Windows driver too!? Oi.

Parity comes in two flavors odd and even. This is clearly odd parity

Just when nvidia are starting to make the right noises towards linux they go do something dumb like this.

Hey, Linus!.... It's finger-time!
