I rely heavily on dual monitors with many terminal windows and workspaces. For many years (since SunOS4 I think) I've configured dual monitors as independent screens (i.e., :0.0 and 0:1). From within a terminal on one screen I could open a new terminal displayed on the other screen, and cut&paste worked seamlessly across any terminals. Since I moved from Centos6 to Centos7, this seems to be a real challenge. With the latest Centos7 and gnome-terminal, cut&paste works fine amongst gnome-terminals on the same screen. However, it does not work at all amongst gnome-terminals on separate screens. I noticed this does not apply to some other apps I tried. For instance, cut&paste works fine across screens for firefox and openoffice. Cut&paste FROM other apps into a gnome-terminal on a different screen also works, while cut&paste TO other apps from a gnome-terminal does not. I installed xterm and it seems to work fine, but I'm hoping to avoid going back to it. I think this is related to gnome-terminal as opposed to my graphics driver (NVIDIA-Linux-x86_64-352.63) or window manager (XFCE4).
I'm guessing the reason is that gnome-terminal uses GTK+3. The release notes for 3.10 have this: * GDK has been changed to allow only a single screen per display. Only the X11 backend had multiple screens before, and multi-screen setups (not multi-monitor!) are very rare nowadays. If you really need multiple X screens, open them as separate displays. But, it looks like it was added back in (or at least support for the clipboard was added) in 3.17.6: https://git.gnome.org/browse/gtk+/commit/gdk/x11?h=3.17.6&id=55edc81c10742bf3e410168f6dc317f8aca05938 -- Cheers, Sven Arvidsson http://www.whiz.se PGP Key ID 6FAB5CD5
