[SOLVED] Nvidia twinview (dual-screen) fullscreen video and panels--HELP

[vprasaj]

I set my two monitors in nvidia settings to twinview. It works.

But I can't get panels over both screens.

And video fullscreen is only on one display and not over both.

Is there a way to make this work? Any advice is very welcome.

Nevermind.

I solve it.

I just enabled Option Xinerama.


Option "Xinerama" "0"

Changed to:


Option "Xinerama" "1"

And it works. :)

ah, handy tip, cheers.
but I actually prefer having my second monitor panel/icon free

[vprasaj]

It's a matter of taste.

You can move icons to only one monitor.

Well, for me, my desktop is now complete. \\:D/

I'm happy that you found this handy.

Cheers.

Do you have any success in making maximize work only on one screen, not both? I used nvidia-settings to setup twinview, and now clicking maximize expand window to both monitors :((

[pavelbrilow]

Ok, I just managed it by myself.
Added
Option "NoTwinViewXineramaInfo" "False"
to my xorg.conf.

Hi!!!
I just want to add this:
I had the contrary of your problem: fullscreen on both monitor with dualview, so unable to watch a movie! And idem for appplication: So complicated to use.

So I saw you had the option in Section "Screen"
Option "TwinViewXineramaInfoOrder" "CRT-0"
And I did not have this option, I had the contrary:
Option "NoTwinViewXineramaInfo" "true"

So now, I comment my line, and add yours:
##Option "NoTwinViewXineramaInfo" "true"
Option "TwinViewXineramaInfoOrder" "DFP-0"
And it's OK!!! Thanks!

So I guess what you want is:
Option "NoTwinViewXineramaInfo" "true"

I did not use the "classic" Xinerama, I had problem with the zoom in Compiz with it.

See you.

Hello,

is this Xinerama behaviour a full or nothing stuff or is there a possibility to have it both (at the same time).

In detail:
My preffered setup on my dual monitor workspace is separated (xinerama off). There is one display that holds the gnome panels the other widget stuff and so on and on each of them windows are maximised to the actual display.

But now there are some special applications like Google Earth I would like to span across both displays.
I found no option for that and manually sizing is not easy because I can not drag the mouse over display borders while sizing. Additionally the window snaps back to the display where more of its half is positioned when grabbing the size cursor on the minor side ... (maybe no one will understand now what I'm talking about :D )

I will stop to talk now to not increase confusion, please ask me if I should explain it more precisely what I mean. Maybe making a video is also an option.. ;)

Ah one thing I forgot: in games it is possible to span across both displays and to get this to work I configured meta-modes. But even if I would have an idea on how to apply meta-modes to normal windows, this would not be perfect since it possibly will overlap all panels etc then.

Any hints?

//Edit:
Just tried out Xnest, but the Xnest window also is limited to the geometry constraints of the physical display.
How to override this? Is this a kind of "rescue/prevent off screen" feature?

//Edit2:
Hey ... its me again! :D :D
I just managed it to work with Xephyr "Xephyr :1 -screen 3000x1000" and this looked good at the beginning and will be a good workaround for normal tasks I want to have spanned.
But, for the example task Google Earth this was not good, as it complained of being run in Software Acceleration mode and this performance was really bad.
So it gets more interesting, but it still is not perfect - any ideas?
