NVidia TwinView


I have a Nvidia GeForce twinview card, and today was the first time i actually tried to take advantage of that.


I setup my XF86Config following Acid_Kewpies' XF86Config with my options of course and when i tried to startx it failed with a bunch of Nvidia unresolved symbols... Then i went to the NVidia README and setup TwinView as they suggest, and.. It worked!


Great! Now i have a dual head display similar to using Xinerama, but without Xinerama. In other words i can move apps, and the mouse between monitors, all is cool, but apps appera always in the middle of two monitors when i start them up, in other words if i start Opera, half of it is on Monitor1 and other half on Monitor2, now that is not a problem since i can just move the app. but the problem is when i maximize apps they span through both monitors, and its hard to surf the web like that!
And then games (like UT) start with a resolution of about 800x600 in the center of the two monitors (like other apps) and the other area is black, and unusable.
In other words apps think that i have one huge monitor and place apps like that, which is not good.
I want to make it so that if i start a app on one monitor, it will stay on it and not span over the other one when i maximize. Now you would say "Just turn Xinerama off" But there is no Xinerama, thats the problem, it's TwinView, not Xinerama.
So does someone know how to do this? There is some info about this here:
http://download.nvidia.com/XFree86_4...880/README.txt in Appendix i but i didnt understand much cuz it's first time i'm doing this. Its about MetaModes and even if i set them up correctly i dont think it will solve the games problem.
So does someone have an idea how to have two start two X sessions using TwinView, since that would be the best and easiest solution.
Sorry for the long and messy/hard to understand/complicated question, but i would need help on this.
Thank you very much in advance!

1)
Option "TwinView" "boolean"
Enable or disable TwinView. Please see APPENDIX I for
details. Default: TwinView is disabled.

To disable TwinView just set this option to False.

2)

o TwinViewOrientation
This option controls the positioning of the second display
device relative to the first within the virtual X screen, when
offsets are not explicitly given in the MetaModes. The possible
values are:

"RightOf" (the default)
"LeftOf"
"Above"
"Below"
"Clone"

When "Clone" is specified, both display devices will be assigned
an offset of 0,0.



--> Here maybe set the orientatin to Clone, and see what you get.


I don't have a Nvidia Card, but I am guessing these will work, based on the README.

Sfin: Thanks for help! I tried "Clone" and holy $#i7 that was weird. I get X started on both monitors, like i wanted, but there is a mouse on every monitor too, and if move the mouse the cursor moves on both monitors, also if i click, etc, it does the same thing on both monitors, like a mirror. Is there a way to fix this to have only one mouse that will page over from screen to screen? If no i'll have to go play with MetaModes although i have no idea what the hell they are...
Thanks for help!

Got it to work. I played with MetaModes and found one that will disable the second monitor ONLY when i run games (change to lower esolution)




Here is the significant part of my XF86Config just in case some one has the same problem and searches the forum one day, like i did today: Anyway here it is:




Section "Screen"




Identifier "Screen 1"




Device "NVIDIA GeForce"




Monitor "My Monitor"




Option "TwinView"




Option "SecondMonitorHorizSync" "31.5 - 48.5"




Option "SecondMonitorVertRefresh" "50-90"




# Option "MetaModes" "1024x768,1024x768;800x600,800x600;640x480,640x480"




Option "MetaModes" "1024x768,1024x768;640x480,NULL"




Option "TwinViewOrientation" "LeftOf"




Option "ConnectedMonitor" "DFP, DFP"














And for future reference, all your NVIDIA Linux question are probably already answered here: http://www.nvnews.net/vbulletin/index.php?
(There is a Linux section)







Hope that will help someone one day.




and thanks for your help guys!
