Comment 40 for bug 1727842

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.
