twinview+play a game ?! = impossible ?

i have configured twin view, all works good

exept : games and mplayer

the problem is they run on the two screen at the same time

first screen is 1024*768 and slave is 640*480 (dont support more :( )

i like to use the second screen to survey some logs or chats

what can i do to have a game workin in fullscreen on first display same for mplayer ?

i have tested without twinview (two xscreen section etc) the problem is that use all my memory and gnome is slow

i have best perf with twinview ...

did you mean you use xinerama?

better not use xinerama,

xine (video-player) has some configuration with xinerama...

The problem is rooted in the way twinview works.

Because twinview fools your os into thinking it's just a double wide screen (in my case 2560x1024) Any applications that load would span both monitors, without really knowing you're running twin monitors.

So twinview fakes standard xinerama hints to your window manager and to apps. However certain apps are coded to over ride certain window manager hints, which in turn can either make the app work correctly, or incorrectly.

Blender for example is coded to hint the WM to get rid of borders and to go full screen. It works great for my purpose of dual screens.

Mplayer or full screen games get the impression from X that you've got one double wide screen, so the app nests it's self in the center of the two screens, thinking that it's only one. This is a feature believe it or not, but it's rotten one if you've got two screens.

Mplayer for example runs full screen borderless across both screens.

As of right now, the only thing you can do is create a seperate config file, or seperate layout and just restart your x-server everytime you want to play a game, or watch something.

It's quite a pain, but there's currently no way to have an app communitate with the drivers to say it wants to be on one screen, not both.

does xinerama give you the ability to work a screen seperatly?

and can you not get a metamode like this? : "1024x768,1024x768;1024x768,null" for example

then just by pressing CTRL-ALT-KP_PLUS you'd go single-monitor and can play games on one screen...? (maybe you'd need the randr extension, I'm not sure)
