Nvidia Twinview

I'm running an Nvidia Quadra Pro video card with dual monitor out, one digital one analog (not that it matters), the problem is I have one good monitor and one crappy monitor. I have a dual head setup working and all thats not an issue. The problem is things like maximizing windows doesn't work (trys to put it across both monitors) same with new windows. The problem is made really bad due to the fact that the LCD can do 1280x1024 and the crappy CRT can only do 1024x768, so X thinks the entire desktop is really 1280x1024 which doesn't exist on the crap monitor.

Anyone have any working Xorg.conf for a similar setup? Good graphics card, one good and one crappy monitor?

I'll stick mine below.

Look herefor some ideas.
As for a window taking up both screens, the WM has to have support to be able to maximize only to one screen. KDE for example has it when the relevant parts are compiled with the xinerama use flag.

Maybe this can ease the work:
* media-tv/nvtv
Available versions: 0.4.5 ~0.4.6 ~0.4.7
Installed: no
Homepage: http://sourceforge.net/projects/nv-tv-out/
Description: TV-Out for NVidia cards

* media-tv/rivatv
Available versions: 0.8.2 ~0.8.5-r2 ~0.8.5-r3
Installed: no
Homepage: http://rivatv.sourceforge.net/
Description: kernel driver for nVidia based cards with video-in

Also if you use kde you need xinerama support in you USE flags

I have a setup with three monitors on 2 nvidia video cards. They are all the same resolution, but that can be easily changed in the xorg.conf file. I use kde and if you build it with the xinerama use flag it has a multiple monitor setup tab in the monitor section of the perpherals control panel for easy setup. It also only maximizes a window on one monitor instead of both. Here's my config file:

It sounds like your trouble is in your window manager. Check your use flags for "xinerama"

What can I say ... similair setup, similair problem.

I think, that this is a problem related to nvidia twinview, because everything works fine with two graphic cards

I found my digital -> analog adapter today, was happy to see videos on my crappy monitor too and now there are problems:

1. Windows maximize on both monitors, just like xdm, gdm, kdm, entrance, any sort of panels and the nvidia logo do
2. I can _scroll_ on my right monitor (I don't want it ...), but just to the right, so it becomes even more weird.

My second monitor is small, so I prefer 1024x768 on it, but for testing purposes, I changed this to 1280x960 (like on the main monitor), now I cannot scroll anymore, but all the other problems stay

Gaming seems to work fine, testet with doom3.

When using two graphic cards (one Nvidia Geforce 4 4200 Ti, one old ATI), everything works just as one could wish.
Windows maximize on the first monitor, [xgk]dm show up on one screen, the panel looks right in kde, gnome and xfce4. I reemphasize that I'm using Xinerama in both setups.

So if you want to hear my suggestion (til someone solved that creepy problem), get yourself a PCI graphics card from the hardware cemetry ...

Sorry for doubleposting, but I don't think anyone will recognize this if I don't:

I solved it.
almost.

Bad news: The desktop-scrolling-probling persists with different resolutions.

BUT (good news:), I did a little RTFM and found the following:

Sorry for the third post, but I now found the cause of the scrolling problem!

It seems to be the Modes line in your [xX].*\.conf, when you deactivate every mode besides the one you want to use, everything works just fine. This is my ne modes line:

could someone please post the *working* xorg.conf when using 1 video card that has 2 heads, with 2 monitors that use different resolutions.

I've been going at this problem in another forum for awhile
