I am VERY interested in continuing work on this. I'm now running 19.04 and the problem persists. I cannot change the status so please update it.
There has been a long running discussion on the Xfce buglist which you can review here: https://bugzilla.xfce.org/show_bug.cgi?id=15116 The problem seems to be that the move to gtk3 is the source of the condition as it has dropped support for multiple monitors. Olivier Fourdan is maintaining xfwm4 and he has apparently done something internally that allows X11-aware applications to be launched on a separate display (:0.1) in addition to the native display (:0.0), but none of the other Xfce components such as the panel, desktop, etc have the ability to run more than one instance on the main display. In this forum discussion: https://forum.xfce.org/viewtopic.php?pid=50336#p50336 member gert pointed to this patch in the gtk3 repository that seems to indicate that multi-screen support has been added back into the toolkit. https://github.com/xfce- mirror/xfwm4/commit/b52c2f5b740434803342c471d4dcb5dd62eb99a1 However, this patched version of gtk has not yet made it into a Ubuntu distribution. Losing multi-headed independent desktop support has been a terrible step backwards for Ubuntu. Please look into this more closely and make sure that the 19.10 release gets the tools required to get this capability restored. I'll provide additional info if necessary. However, as an end0user in this arena, I don't have more insights into the interactions of the display components making up the various desktop environments. On a couple of other forums, I asked whether there was another flavor of Ubuntu that was properly supporting multiple screens. I received zero replies. Multiple independent desktops is critical (as opposed to Xinerama mode) so that material can be displayed statically on one display while changing workspaces on the other screen. ** Bug watch added: Xfce Bugzilla #15116 https://bugzilla.xfce.org/show_bug.cgi?id=15116 -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg-server in Ubuntu. https://bugs.launchpad.net/bugs/1822181 Title: Ubuntu 18.10 broke dual-screen dual-desktop configuration To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg-server/+bug/1822181/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
