FYI, Xinerama is in the process of being deprecated and replaced by
RandR. Currently RandR is not fully functional as a replacement for
One result of faulty driver implementation of an incomplete RandR is
that using some recent nvidia or ati proprietary drivers to implement a
xinerama-like desktop stretched across two displays a full screen
maximization of a window would stretch across both displays. This is an
artifact of the incomplete RandR implementation and can be remedied by
disabling RandR when implementing this xinerama-like screen.
Please note that these drivers are not actually using xinerama but
proprietary code to do this.
Currently, if you are using the latest ati or nvidia drivers the only
reason to use Xinerama is to have independent displays which you can
drag windows across if you are using multiple gpus When the latest
nvidia and ati proprietary drivers do use Xinerama, RandR is disabled.
One thing that can be done with these drivers (at least with ati's
fglrx) when using xinerama is that compiz can be enabled on one screen
and that screen can be rotated independent of the other displays.
Multiple independent displays with multiple independent view ports.
RandR has not been implemented for this yet in any display manager.
The open source driver devs are following X org and have already
deprecated xinerama in favor of randr.
Apparently the ability to rotate the screen on your notepad is far more
important than having more than one independent display/viewport since
it seems to be the driving reason for tossing xinerama into the trash
and adopting randr before it is ready to actually be implemented by the
display managers to replace xinerama.
Anyway, I hope this clears up some of the confusion about this little
xinerama dust up.
