i can confirm that the communication to the monitor on crt-port is not like it was with the drivers before.
It does not get all the possible modes as it was before. Twinview itself is working, but not with the modes as it was.
For me its missing the resolution 1280x1024 on that crt.
In xorg.log this may be the reason for this:
NVIDIA(GPU-0): Unable to read EDID for display device CRT-1
In my xorg.conf the twinview part:
Option "TwinView" "1"
# Option "TwinViewXineramaInfoOrder" "DFP, CRT, TV"
With this minimal config X is starting up and usable. With the commented option activated the driver will lock the PC including keyboard so that it is impossible to switch to a tty to get the control back. A second PC with ssh is needed (That behavior is described in other posts in this forum). The xorg.log in that situation states as last line:
NVIDIA(0): Enabling RENDER acceleration
without any EE or WW lines or any more diagnostic lines that could point to a problem.
