It doesn't work for me
I also have tried with 185.19 beta version - result was the same - six screens.
1. do You have the same GeForce G105M card with PCI ID: 06ec ?
2. was there on Your computer also situation with six screens on monitor?
3. maybe can You post Your xorg.conf?
Sorry, but I'm desperred with this problem.
Thank You with advance.
