There is reason for that. Nvidia does not disclose much of chip =
internals (like memory layout etc), so to write decent open source =
driver is not possible, hence only generic functions are supported by =
open source nv driver. Anything a step off usual, say dual screen with =
different screen resolutions - quite often thing in the Department I =
support - is not possible. You have to install Nvidia proprietary binary =
driver (I often correct those who say =E2=80=9Ccompile nvidia driver=E2=80=
=9D. Nope! What one is compiling is interface between proprietary binary =
driver and specific kernel).

Same observation here. ATI chip internals were decently described by =
manufacturer in their documentation, so open source driver developers =
can write excellent drivers supporting pretty much all capabilities of =
the chip[set]. Such were my observations for a couple of decades, even =
after AMD bought ATI. Someone, correct me if you noticed things changed, =
which I hope they didn=E2=80=99t.
