I think that the upstream bug https://gitlab.gnome.org/GNOME/mutter/issues/878
may not be the same issue. This bug has "X11" in the title, and so it really refers to behavior under X11. On Ubuntu 19.10, if I run an X11 session then copying/pasting fails very often, especially in LibreOffice. For this reason I switched to Wayland several weeks ago. Under Wayland, copying/pasting still fails occasionally, but far less often. I saw copy/paste failures dozens of times per day under X11, and now they happen maybe once or twice per day in Wayland (with intensive use of LibreOffice in both cases). In a comment in the mutter bug linked above, Carlos Garnacho wrote This is wayland specific. So it is unclear to me that the patches linked there (which are to both GTK and mutter) will fix the problem in X11. Has anyone tried to reproduce this copy/paste problem after applying these patches under X11? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1852183 Title: [X11] copy/paste (clipboard) is broken in Ubuntu 19.10 To manage notifications about this bug go to: https://bugs.launchpad.net/df-libreoffice/+bug/1852183/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
