Anyone have a multi-card, multidisplay setup working with gnome 3 and Fedora 15?
I have two nvidia 9500GT cards driving 4 monitors (2 per card) using the proprietary nvidia drivers (270.41.19) The setup had been working fine with the previous version of Gnome and Fedora 14. I was using xinerama to have one large desktop spanning 4 screens. No problems until I upgraded. KDE works after configuring using nvidia-settings, however gnome 3 is not useable. I get two screens black (but with mouse pointers when I move the mouse) and the right two screens with the background but the activities corner in the right hand side of the right most screen, rendering it useless.
the right two screens with the background but the activities corner in the right hand side of the right most screen, rendering it useless.
That is the way GNOME shell was designed i.e. to have a single Activities button/Hot corner on the primary monitor. See the _relayout() function in main.js for the algorithm.
Thanks for replying. That part I understand it's just that it shows up on the right hand edge of furthest screen to the right so that when it expands I can't see but a slither of it. I tried changing the primary screens but to no avail.

Same problem with my setup although I am using 3 monitors. I have X working correctly using Xinerama but GNOME3 will only run in 'Fallback' mode. I don't think GNOME3 works with multiple graphics cards very well yet. If I change my setup to only use the two monitors on one card then GNOME3 works perfectly.
I took a look at the xorg.conf you attached and it is only configured for two screens. This might be your current problem. I have attached the 3 config files I put in /etc/X11/xorg.conf.d for my setup. This might help you.
I have 2 cards, 8600GT + 9500GT. Two monitors on the 8600GT (Middle and Right) and one on the 9500GT (Left). I remove the /etc/X11/xorg.conf file created by the rpmfusion nvidia package and use the defaults with my specifics in /etc/X11/xorg.conf.d
I agree that the xorg.conf looked funny. That's what was produced by the nvidia-settings application. I made my own up that seems to make sense. So far this "works" but I believe I am in fallback mode. System Monitor info claims Gnome 3.0.1 but when I logged in as another user I got the fallback mode notification.
Attached is my Xorg.0.log and nothing seems violently wrong. There is a warning about Xinerama and RandR has likely been disabled by the X server.
Same problem here. Unfortunately does Fedora switch the display setup by connecting the secondary display, so I have no chance to do some fixing. I could solve it for now, if I switch to a lower resolution, for me the lowest, before plugging the display. The desktop would now be extended to the new display by connecting the cable and I can setup my preferred settings.
I have installed Fedora 15 and am able to get two monitors working with no problem using Nouveau with a NVidia Quadro NVS 290 card. I have Fedora 15 installed on another machine with a NVidia Quadro NVS 450 card and I am trying to get the desktop to span across 3 monitors which worked in Fedora 14. Since Nouveau seems to only handle two monitors I installed the NVidia drivers from rpmfusion. Using nvidia-config I am able to set one monitor up as one x server and use twinview (xinerama) to link the other two monitors as another x server. When I boot the computer the login screen comes up on the primary monitor and the other two are filled in with the Fedora 15 background but at a different resolution (monitors are the same hardware). When I login the gnome-panel aborts and I just have the background and the cursor. I was getting the SELinux issue mentioned here https://bugzilla.redhat.com/show_bug.cgi?id=694918 so I disabled SELinux and relabelled the filesystem. Problem still persists.
Is it possible to use three monitors with Gnome 3? and the NVidia Quadro NVS 450?
I was able to get gnome shell working with two monitors and a NVidia Quadro NVS 450 graphics card with some minor adjustments. I have the nvidia drivers installed from RPMFusion and using the NV Forum as reference I added the following to xorg.conf:
This forced the use of /usr/lib64/xorg/modules/extensions/nvidia/libglx.so for GLX.
I am not using Xinerama. I am using TwinView.
When I try to add a third monitor I must configure it to use another xserver. When I do this all three monitors show the Fedora 15 background but they all have difference resolutions. When I try to login the two monitors using twinview go black and a message pops up saying:
Oh no! Something has gone wrong.
A problem has occurred and the system can't recover.
Please log out and try again.

Is there a way to get more than two monitors to work with gnome 3 and gnome shell?
I am having the same problem as almost everyone else with a nvidia card running multiple monitors, it seems. I have a nvidia GeForce Go 7600 and was trying to use just two monitors on separate x screens. The screen appears to be working fine, having a background image displayed. But when I go to log in I get the broad, dumbed down, "oh no! something has gone wrong." trying to log in doesn't help at all.
I'm resurrecting this older thread because it seems a resolution other than some steps (which weren't validated) were posted and Google is returning this when searching for "Fedora 15 multiple monitors gnome 3" as the #1 result.
What is the status on this? Has anyone tried those steps?
TwinView mode indeed works with latest nvidia drivers. Unfortunately, this mode is unusable if your display devices have different refresh rate (this is common for Monitor+TV tandem) because of noticeable "tearing" glitch on second display (say TV).
Separate screens mode with nvidia drivers is not supported and unlikely if will be supported any soon (incompatibility between Gnome 3 rendering and nvidia drivers).

Sadly it looks like the standard Gnome 3 experience is still not workng for multiple cards.
I have installed F16 (Gnome 3.2.1) and can only use the Gnome desktop in fallback mode (screenshots attached).
If I try use Gnome 3 in standard mode then the background is displayed on all three monitors but nothing else. I can login by typing <Enter>, my user password and then <Enter> again. A process list shows all of my autostart apps running but nothing is displayed on the desktop except my two gkrellms.
If I change my Xorg config to only use two screens (on same card) then the standard mode works without any problems.
I will do some more digging to see what exactly is tripping Gnome 3 up with regards to multiple cards. Will report back here what I find.
Linear Mode
