Thanks for the reply. The PC is a desktop - Dell Precision Tower 5810. However... I may have narrowed this down to something related to my Dell USB soundbar. I've disconnected it and the issue goes away.
The soundbar is a Dell AC511. -- 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/1770629 Title: Keyboard and mouse lockup when using media keys to adjust volume To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-settings-daemon/+bug/1770629/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
