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). >> After 20 years of being loyal customer of nVidia I have switched to >> AMD RADEON RX580 simply because they support Open-Source while nVidia >> does not. >=20 > In the past, ATi had excellent open source support for all the > features of the graphics card, and there was one (!) driver that > supported them (named "ati").

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.
