https://bugzilla.kernel.org/show_bug.cgi?id=214899 --- Comment #17 from Johannes P (johannes.penssel@xxxxxxxxx) --- Looks like the mic mute key and the brightness keys do not behave identically with the ideapad-laptop module unloaded after all. While playing around with ACPI EC debugging today, I was able to produce output for everything (including the otherwise "invisible" KB backlight toggle) except the brightness keys. This included the mic mute key and other keys reliant on ideapad-laptop. Without the module, pressing these keys still triggered EC debug output. Just as a correction to my above claims. -- You may reply to this email to add a comment. You are receiving this mail because: You are watching the assignee of the bug.
