I think the wider issue here is that this is a specific change in functionality, wherever it may be. Under the prior version of Ubuntu, configuring a second monitor/second video card as a seperate X screen would result in the second screen being set up the same as the first when it came to window decorators. Since the upgrade, this functionality has changed, and the X-Server is launched without a default window manager, let alone a clone of the first monitor's window manager setting.
Now, there is completely non-obvious behaviour happening, and for the majority of first-time users, the fact that the second monitor *does not work as expected* will cause consternation. Contrary to the low improtance assertion, there are a number of valid use-cases for configuring a second monitor with a seperate X-Server. I use a seperate X-Server on my HDMI-out for general display work when I'm using my laptop for other purposes. I've used it in the past for presentation work, or for displaying server monitoring services and displays in a way that doesn't interfere with my primary workspaces. Not every use case for multiple monitors has them next to each other, or even in close proximity. As I type this I have a monitor being driven by a seperate X Server at the end of a 5 meter HDMI cable - if it was running in Twinview then when I switched workspaces I'd lose what was being displayed in the external monitor. And I'm not the only audience for that second screen. I'd heartily disagree that this is of "Low" importance, although I wonder if the actual bug is in Compiz, or in the way X (or Ubuntu for that matter) handles the user-selected configuration of multiple X-Servers, especially where a second display is launched without a default window manager (if one is not set for the primary display), and where there is no obvious way to run a display manager for those without comand line knowledge. I struggled myself to resolve this, and I've been using Ubuntu as my only OS (work and home) for the past 5 years or so, so I shudder to think of the reaction of a newcomer to Ubuntu when they run into this kind of issue. -- You received this bug notification because you are a member of compiz packagers, which is subscribed to compiz in Ubuntu. https://bugs.launchpad.net/bugs/764051 Title: Second monitor useless in dual desktop mode _______________________________________________ Mailing list: https://launchpad.net/~compiz Post to : compiz@lists.launchpad.net Unsubscribe : https://launchpad.net/~compiz More help : https://help.launchpad.net/ListHelp
