I can confirm a very strange behaviour of media keys after release- upgrade from 16.04 to 18.04 (unity-desktop). At first, media keys seemed to have stopped working at all, but that is not the case. If I press for example the "mute" key, it takes about 25 seconds before the muting succeeds. At the same time, the syslog says:
May 9 09:43:29 bionic unity-settings-[7849]: Failed to connect to proxy Switching 'commands' on/off via ccsm does not help. On the loging screen when using gdm3, all keys work as expected. On the loging screen when using lightdm, the bevahiour is as described above. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1727842 Title: Volume and Mute buttons on keyboard not doing anything in Unity after upgrade to 17.10 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/unity/+bug/1727842/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
