  • Disable Xinerama info

    I have 3 screens, 1920x1080 each, vertical. Two on one GPU (GTX 470, Screen 0), and One on another GPU (GTX 465, Screen 1).

    I would like to *disable* Xinerama info so that applications are reported that there is just one, large, 5760x1080 screen. Is there a way to do this? Specifying --no-twinview-xinerama-info using nvidia-xconfig reports one 3840x1080 screen and one 1920x1080 screen, but I would like to disable all Xinerama information coming from the X server so that applications think they're running on one big monitor.

    Anyone do this before?

    The nvidia driver only allows overriding of it's own xinerama information.

    But you're using the X.org Xinerama extension to join your screens. Having that extension report different screen geometries would require hacking said Xorg extension.

    You could also hack (or configure) your window manager. Some allow overriding Xinerama info, some don't.

      Yeah, this is apparent.

      There is a method to do this, but I'd much rather avoid nonstandard setups...

      WINE is being used to run some applications, so Wine 'is' the window manager in certain scenarios.

      Hmm. Why didn't the X developers think of allowing someone to just omit screen boundary information in Xinerama?
