[SOLVED] 2 Screens and only black screen

[gwydion.dot]

Hi


I have a little problem with compiz/compcomm. When I set up my second screen, and start compiz/compcomm, I have got only a blackscreen.
Is there no support atm or is it a bug? I have a nvidia card with 2 DVI-Outs.


Each search is separated view.


Any solutions?

If I recall correctly, this functionality (managing two separate displays with beryl) never made it into any stable beryl version, just in the development code. I don't even know how well it worked when it was available in beryl, but I'm going to go out on a limb and say it has not made it into compiz.

However, it should work just fine if you switch to twinview. Since it's one display, you won't be able to spin the cubes independently, but compiz should at least work for you on both monitors this way (it works here).

Hi


Ok, thanks. Is there a other way to have a second screen? I only need it to watch movies on a beamer. No need for compiz or so, only need a xserver.

[adamk]

Why not just use twinview?

The beamer is not running all the time, and when I run twinview, some parts are on the beamer. That is not so pretty...

I found a solution, how works very well!

Add this arguments to compiz.

[code:ce238]
--display :0.0 --only-current-screen
[/code:ce238]

Out of curiousity, are you then able to run beryl on the other screen, or do you have to run another window manager on it?

Hi

No, on the second screen is no windows manager. But I only use the screen for watching movies, and thats no problem so. ;-)
