Twinview as separate screens, not stretched


I have pasted my XF86Config file because I have gotten my computer and tv to show either a clone with both showing the same thing on both screens.

When I cahnge my XF86Config file to have the tv rightof, then it stretches the screen across both.

The problem is, when I want to watch a DVD just on the tv the screen maximizes to just the tv, but it is stretched because of the the stretching of the screens.

I tried to change the resolution to 1024x1536, which I thought would stop the stretching because you wouldn't be stretching 768 across both screens, but X wouldn't start in this mode.

Me too :-\

I've got the exact same problem. I've got an NVidia Quadro 280 NVS, and I'm running Gentoo Linux 2004.1. TwinView setup was a piece of cake, but now my window manager (KDE 3.2.2) does not detect that there are 2 screens and not just one, so it stretches everything over both screens, including the task bar, the startup screen, etc.

I did have this working previously, but that was with FreeBSD 5.2.1, IIRC.

I'm using version 1.0-5336 of the NVidia drivers. Perhaps it's an error in those drivers, because I've tried virtually everything, including:

- Reinstallation of the nvidia-glx and nvidia-kernel stuff
- Added to XF86Config: Option "Xinerama" "off" in the ServerFlags section
- Added to XF86Config: Option "NoTwinViewXineramaInfo" "off" in the Driver section
- Changed resolutions for the second monitor

The problem MAY be that the NVidia drivers are not able to export Xinerama-compatible information to the window manager, because the 'normal' XFree86 Xinerama extension is loaded and in the way.

I have tried to disable it, but I'm not sure how to do it. The XF86Config man file indicates that Xinerama is by default disabled, so I would think that I should not have to do anything...

The nvidia documentation is here:
ftp://download.nvidia.com/XFree86/Li...0-5336/README/

It says explicitly that if the Xinerama extension is enabled in XFree86, then the NVidia drives won't be able to publish Xinerama-compatible information to the window manager.

When I check my XFree86.N.log file (where N is the ID), then I do see that some XINERAMA extension is loaded and then initialized. I'm just not sure whether that is the XFree86 XINERAMA driver, or the Nvidia driver publishing a XINERAMA-compatible interface of some sorts....
