https://bugzilla.kernel.org/show_bug.cgi?id=216824 --- Comment #16 from Hans de Goede (jwrdegoede@xxxxxxxxxxxxxxxxx) --- That is weird. You could try adding the following line to the list MSI keys in hwdb: KEYBOARD_KEY_55=f21 But as the evtest output shows scancode 85 / 0x55 is normally used for a key found on some Japanese keyboards and the Fn + F4 keypress is not just sending 0x55 it is sending windows-key + ctrl + 0x55 . You say this did work under KDE ? -- You may reply to this email to add a comment. You are receiving this mail because: You are watching the assignee of the bug.
