Either this change will make the rfkill button work (good), or not (current behaviour). Given the code paths, validating similar SKUs for non-regression is a good enough confidence level that this change doesn't regress other/unrelated machines. It's a low risk to accept this change as is, because the worst case scenario is a no-change in behaviour. The upside is that it may have fixed rfkill button.
Also if this change doesn't fix the rfkill buttons on these laptops, it would imply that later releases and upstream master are also still broken and unfixed. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1762385 Title: dell_wmi: Unknown key codes Status in OEM Priority Project: Triaged Status in linux package in Ubuntu: Fix Committed Status in systemd package in Ubuntu: Fix Released Status in systemd source package in Xenial: Fix Committed Status in linux source package in Bionic: Fix Released Status in systemd source package in Bionic: Fix Released Status in linux source package in Cosmic: Fix Committed Status in systemd source package in Cosmic: Fix Released Bug description: [Impact] * Bogus keycode messages produced by the kernel / user annoyance * rfkill keyboard shortcuts not working as intended on some Dell machines [Test Case] * check that there are no spurious kernel messages about unknown keys in journalctl upon RFKill key presses * check that RFKill key presses work correctly and kill/restore RF capabilities [Regression Potential] * The change is scoped to particular SKUs and thus should only affect them * It is related to matching gsd support, which is in-place on xenial and up [Solution] Cherrypick upstream commit https://github.com/systemd/systemd/commit/cab01e9ecf1c69656785e64f5fc94cd4ed09e57f [Original Bug report] RFKill key produces these messages in kernel log: dell_wmi: Unknown key with type 0x0010 and code 0xe008 pressed This key code is a notification and should be added as KEY_IGNORE here: https://github.com/torvalds/linux/blob/master/drivers/platform/x86 /dell-wmi.c#L263 ProblemType: Bug DistroRelease: Ubuntu 18.04 Package: linux-image-4.15.0-15-generic 4.15.0-15.16 ProcVersionSignature: Ubuntu 4.15.0-15.16-generic 4.15.15 Uname: Linux 4.15.0-15-generic x86_64 ApportVersion: 2.20.9-0ubuntu4 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC0: dmig 2737 F.... pulseaudio CurrentDesktop: ubuntu:GNOME Date: Mon Apr 9 18:09:03 2018 InstallationDate: Installed on 2018-03-27 (12 days ago) InstallationMedia: Ubuntu 18.04 LTS "Bionic Beaver" - Alpha amd64 (20180327) MachineType: Dell Inc.
