I restarted gnome-shell with Alt-F2 r and media keys started working. This is probably a duplicate of one of the other "media keys randomly stop working sometimes" bugs. I was searching for the particular error message and found none -- probably because the error message itself was only added relatively recently (in gnome-settings-daemon 3.20), while upstream tries to figure out what causes this bug.
I haven't located the upstream bug report yet. ** Bug watch added: GNOME Bug Tracker #758302 https://bugzilla.gnome.org/show_bug.cgi?id=758302 -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gnome-settings-daemon in Ubuntu. https://bugs.launchpad.net/bugs/1659517 Title: media keys stopped working: "Could not find accelerator for accel id 123" To manage notifications about this bug go to: https://bugs.launchpad.net/gnome-settings-daemon/+bug/1659517/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
