I think that > Xinerama is obsolete, but don't know. From whatever I've read it is. xrandr is used rather than a formal definition and the virtual screen size is updated as required. I use this quite frequently for a presentation screen. Using xrandr you can determine mode, placement, etc. From that specific problem... not sure. I believe only one card can be used at a time unless defined in a certain way in the conf - but I think you already know that. But then that requires ServerLayout options set as well. It may even require using "screens".

I'd also be interested to know if there is a way to define multiple monitors on separate screens (screen0, screen1, etc as 0.0, 0.1, etc). > _______________________________________________ > freebsd-x11@freebsd.org mailing list > http://lists.freebsd.org/mailman/listinfo/freebsd-x11 > To unsubscribe, send any mail to "freebsd-x11-unsubscribe@freebsd.org"
