This is a note to let you know that I've just added the patch titled HID: lenovo: Map mic-mute button to KEY_F20 instead of KEY_MICMUTE to the 5.10-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=summary The filename of the patch is: hid-lenovo-map-mic-mute-button-to-key_f20-instead-of.patch and it can be found in the queue-5.10 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. commit 72e0f93ae496f9d6545abee11ea479ec0b47b658 Author: Hans de Goede <hdegoede@xxxxxxxxxx> Date: Sun Apr 4 10:04:29 2021 +0200 HID: lenovo: Map mic-mute button to KEY_F20 instead of KEY_MICMUTE [ Upstream commit 617103246cfd19af837e4cb614ba9f877c4f7779 ] Mapping the mic-mute button to KEY_MICMUTE is technically correct but KEY_MICMUTE translates to a scancode of 256 (248 + 8) under X, which does not fit in 8 bits, so it does not work. Because of this userspace is expecting KEY_F20 instead, theoretically KEY_MICMUTE should work under Wayland but even there it does not work, because the desktop-environment is listening only for KEY_F20 and not for KEY_MICMUTE.
