I did some testing during the last days, and still this bug remains really strange.. I could not find a way to really reliable reproduce it or make it disappear.
I did several clean test installations of Ubuntu 17.10 and made the following steps after installation: - First boot, log in (Gnome desktop starts) - Install Unity: apt install unity-session, reboot - Second boot, select Unity at GDM login - Test if media keys, power button etc. work. Usually, it seems that the bug does _not_ appear on this second boot. - Do nothing else, reboot. - Third boot: Log in to Unity, test again, if keys work. Usually, the bug appears this time. - On further reboots of the system, the bug may appear or not. Then I did some testing with running 'unity-session-daemon --debug -r', and found out that it is possible to make the bug randomly appear or disappear by restarting unity-session-daemon. The first briefly tests were run on my clean test installation, and afterwards I did some more exhaustive testing on my "main" Ubuntu installation, where the bug had appeared permanently so far. During this "exhaustive testing" I repeatedly restarted u-s-d and checked every time if the keys were working. I had to do this approximately 15 times, until the bug disappeared for the first time and the keys worked! I am attaching two log files: - One containing a log of unity-settings-daemon where media keys etc. _did_ work - Another one with a log of u-s-d where the bug appeared and they didn't work Kind regards, Jan ** Attachment added: "Log file of start of 'unity-settings-daemon --debug -r' that lead to working keys" https://bugs.launchpad.net/ubuntu/+source/unity/+bug/1727842/+attachment/5025609/+files/unity-settings-daemon%20working%20keybindings.txt -- 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
