Not quite so. Example: ATI card, 2 monitors with _different_ resolution,
CentOS 6. Nouveau video driver (which in fact is wrapper using open source
drivers) works perfectly: no need for sysadmin to gig into X11 manual

The same: 2 monitors with _different_ resolution; NVIDIA card. No way! As
open source driver can not handle this in nvidia case (details about how
video RAM is laid out was never disclosed by NVIDIA). So you are stuck
with proprietary binary NVIDIA driver in this case.

More knowledgeable people will correct me. This situation (two monitors
with different resolution) is quite often for me: when graduate students
leave the Department, students who are still here can use their monitors
as second monitor...

These ones always sets me off: video chips with fake non existent video
memory; fake RAID card that are not capable to do even modulus 2 sum...
