Nvidia Removed Linux Driver Feature Due to Windows

The reason seems a little contradictory.

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.

*** and ***

Yet in v295, the Ubuntu user was able to get four monitors up and running. So why was BaseMosaic altered to support only three monitors instead? Nvidia explains. “For feature parity between Windows and Linux we set BaseMosaic to 3 screens,” said “Sandpit” of Nvidia’s Linux team.

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.

“This is like SLI Mosaic mode except that it does not require a video bridge connected to the graphics cards,” the notes read. “Due to this Base Mosaic does not guarantee there will be no tearing between the display boundaries. Base Mosaic is supported on all the configurations supported by SLI Mosaic Mode. It is also supported on Quadro FX 380, Quadro FX 580 and all G80 or higher non-mobile NVS cards.”

It will be interesting to see if Nvidia returns four-monitor support back to its Linux drivers, given that the reason for removing the feature seems a little contradictory.

Yeah, dumbing down the free market competitor is fair. But don’t do the something equivalent to the big guy.

Nvidia is taking a gamble.

Hope they pay for that decision.

Personally, I have placed them on my “Toshiba” list. Technology I will never buy. (Toshiba sold the US Navy sub quiet propeller design to Red China.) 

Like my “Jane Fonda” list, I have a very LONG memory.

Hope you all do too!
