I am using dualhead configuration from first release but it does not work with new driver 1.0-8756 (the CRT-0 output is lost).
My Xorg.0.log:

Bug or feature ?

You're using the ConnectedMonitor option and UseDisplayDevice option to specify a CRT, yet no CRT is being detected. Try removing those options, and if you need more help, please post a bug report.

It is working now!

The problem was in new driver functionality. I used "ConnectedMonitor" option to override/determine output in screen section with only ONE monitor string and older drivers correctly assign screen. Now I should use ALL monitor strings (to override detection) and determine output monitor by "UseDisplayDevice" option.

1) attach monitor before X start (without option "ConnectedMonitor")
2) override detection with config like this:

Section "Screen"
Identifier "lcd"
Option "ConnectedMonitor" "DFP-0,CRT-0"
Option "UseDisplayDevice" "DFP-0"

Section "Screen"
Identifier "crt"
Option "ConnectedMonitor" "DFP-0,CRT-0"
Option "UseDisplayDevice" "CRT-0"

Thank you, M.C>
