Definitely a compiz bug. Using Nouveau and tested on Unity2D and gnome- shell, both of which do not use compiz.
There are certain windows that always open in the second monitor, many of which can be seen in this video: open/save dialogues, images (via Eye of Gnome), and the system settings (not pictured). Others, such as new terminals, videos (via totem), and new text documents open in the focused monitor. This is a small sample portion of windows opening on other screens. ** Attachment added: "bug.ogv" https://bugs.launchpad.net/ubuntu/+source/compiz/+bug/957786/+attachment/2916322/+files/bug.ogv ** Changed in: compiz (Ubuntu) Status: New => Triaged ** Description changed: I have 1 monitor and an LCD TV arranged in as a dual monitor setup with an nvidia card. Ubuntu's display preferences doesn’t recognise the monitors, so I have to use Nvidia settings. The system works but with unity 3d windows keep poping in the monitor I'm not using. It's silly. Because I only turn on the TV when I want to see video, I can't use the system unless I have the other monitor on. Because this is impractical I switched to Unity 2D were this behaviour doesn't happen. Unity 3D should to open windows in the monitor with the focus, or at least give that choice. This behavior also hapens in Ubuntu 11.10. + + https://bugs.launchpad.net/ubuntu/+source/compiz/+bug/957786/+attachment/2916322/+files/bug.ogv ProblemType: Bug DistroRelease: Ubuntu 12.04 Package: unity 5.6.0-0ubuntu4 ProcVersionSignature: Ubuntu 3.2.0-18.29-generic 3.2.9 Uname: Linux 3.2.0-18-generic x86_64 NonfreeKernelModules: nvidia ApportVersion: 1.94.1-0ubuntu2 Architecture: amd64 CompizPlugins: [core,bailer,detection,composite,opengl,compiztoolbox,decor,place,session,mousepoll,wall,move,resize,imgpng,vpswitch,snap,gnomecompat,grid,regex,animation,expo,workarounds,ezoom,staticswitcher,fade,scale,unityshell] Date: Sat Mar 17 09:51:29 2012 InstallationMedia: Ubuntu 11.10 "Oneiric Ocelot" - Release amd64 (20111012) SourcePackage: unity UpgradeStatus: Upgraded to precise on 2012-03-14 (2 days ago) ** Changed in: compiz-core Status: New => Confirmed -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/957786 Title: [nvidia] Windows keep opening in another monitor To manage notifications about this bug go to: https://bugs.launchpad.net/compiz-core/+bug/957786/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
