The company have reportedly crippled their Linux drivers to ensure parity with Windows. An Ubuntu user discovered that after an update to Nvidia’s non-free drivers his system was restricted to support only three monitors. The user wanted to connect 4th monitor using two GTX 560Ti graphics cards with a SLI connector.
A few days ago I tried hooking up a 4th monitor, configured the xorg.conf file, but still only 3 monitors popped up. Then I tried installing the v325 drivers after uninstalling all the ubuntu nvidia packages. This only worked for 2 monitors, because I couldn’t get BaseMosaic working anymore, even not from the NVIDIA GUI after enabling advanced options.

An Nvidia representative responded to the thread stating, “For feature parity between Windows and Linux we set BaseMosaic to 3 screens on GeForce.”
Nvidia chose to disable a feature from their Linux drivers because Windows doesn’t have that capabilities? There are many features in Windows drivers which are not available on Linux so it’s disturbing to see Nvidia chose to further cripple Linux divers to give Microsoft an edge over Linux players.
Another user posted a question to Nvidia developers:
Does “feature parity” takes places only when the features are going to be removed?
I can’t figure out why nvidia went from 4 to 3 monitors on linux instead of just raising windows to 4.
Anyway, if i’m right, optimus support under linux is not on par with windows.
Are you nvidia going to fix optimus on linux, or “for feature parity” are you going to make the optimus support worse on windows too?
Maybe the same applies to stereo3d.
This doesn’t make any sense to me, and all points to some really bad (for the users and probably for the company image) marketing/managment choice.
Oh, and there is still a question waiting for an answer:
- Will it be able in future drivers to support more then 3 monitors again using BaseMosaic?
Which, for “feature parity” means: Are you going to raise the number of monitors to 4 in windows so that “for feature parity” linux users can have it too?
Do a linux user have to post a bug report in the windows forum to have 4 monitors?
“Seriously, This Is Getting Ridiculous.”
Nvidia seemingly needs another round of ‘wrath of Linus‘.
