I'm also experiencing this issue. I first noticed it when attempting to start gnome-terminal using i3. The keyboard shortcut failed to launch the terminal. I've noticed the same behavior intermittently using Gnome desktop as well.
Sometimes restarting resolves the issue. But after a couple restarts, and uninstalling/re-installing, gnome-terminal still fails to launch (it simply returns the dbus accessibility warning). Fortunately I could use the impressive alacritty terminal in the meantime. Here's my system info: ➜ ~ lsb_release -rd Description: Ubuntu Artful Aardvark (development branch) Release: 17.10 Just let me know if any additional information is needed. And thanks to Plamen above for the workaround! Using "dbus-launch gnome- terminal" launches gnome-terminal without issue. -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gnome-terminal in Ubuntu. https://bugs.launchpad.net/bugs/1694454 Title: Can't open gnome terminal To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-terminal/+bug/1694454/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
