As an additional check I once more installed the SRU version (and rebooted):
$ apt-cache policy xkb-data xkb-data: Installed: 2.23.1-1ubuntu1.18.10.1 Candidate: 2.23.1-1ubuntu1.18.10.1 Version table: *** 2.23.1-1ubuntu1.18.10.1 500 500 http://de.archive.ubuntu.com/ubuntu cosmic-proposed/main amd64 Packages 500 http://de.archive.ubuntu.com/ubuntu cosmic-proposed/main i386 Packages 100 /var/lib/dpkg/status 2.23.1-1ubuntu1 500 500 http://de.archive.ubuntu.com/ubuntu cosmic/main amd64 Packages 500 http://de.archive.ubuntu.com/ubuntu cosmic/main i386 Packages ---- Now the problem occurs again. I.e. the first key press still enables the airplane mode just like with the non-SRU version, but the second key press fails to disable the mode: 1.Press key (STILL OK) -> Airplane mode enables. The airplane mode icon appears in the Gnome panel. Wifi turns off. BT turns off. 2. Press key again (THIS IS NOW BROKEN) -> Airplane mode appears to disable momentarily: For a short moment the airplane mode icon disappears from the Gnome panel. HOWEVER, then the airplane mode immediately and automatically re-enables. The airplane mode icon reappears in the panel, Wifi and BT remain off. - does that command works to get out of airplane mode? (Command: gdbus call etc.) Yes, this still works -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to libxkbcommon in Ubuntu. https://bugs.launchpad.net/bugs/1740894 Title: KEY_RFKILL is not passed to userspace Status in libxkbcommon package in Ubuntu: Fix Released Status in xkeyboard-config package in Ubuntu: Fix Released Status in xorgproto package in Ubuntu: Fix Released Status in xkeyboard-config source package in Bionic: Fix Committed Status in xkeyboard-config source package in Cosmic: Fix Committed Bug description: * Impact the airplane mode key doesn't work in GNOME * Test case Use a laptop with a key to activate airplane mode, it should toggle the corresponding mode on/off when used * Regression potential The change adds a new key definition but doesn't touch any existing one, nothing specific to test out of the new key working --------------------- There are a couple things going on, that could be fixed by a Debian or Ubuntu maintainer: - libxkbdcommon needs to be updated from 0.7.1 to 0.7.2. This introduces the RFKill key: https://lists.freedesktop.org/archives /wayland-devel/2017-August/034721.html - x11-proto needs a new release. This commit added RFKill, but it is not in a release: https://cgit.freedesktop.org/xorg/proto/xproto/commit/?id=98a32d328e7195e12c38baa877917335bceffbaf - Likely other X11 packages need to be rebuilt.
