First, excuse my poor English, I'm french, trying to learn English but it's really not easy
I have a 9800GX2, and in nvidia-settings (driver 180.44), I can't use "twinview", I only can have "separate X screen". Here is a screenshot :
When I had a 8600GT, I did use Twinview and compiz with no problem, but now, I can't use twinview and of course, I can't use compiz with xinerama.
What's the problem? Is there a driver that correct that bug ?
Thank you for helping.
