Hi! With up-to-date thinkpad_acpi.ko driver on ThinkPad T480s I'm seeing a strange behavior of LEDs which are integrated into mic mute (Fn+F4) and mute (Fn+F1) keys. When thinkpad_acpi.ko is not loaded, then mute key is working fine. When pressed, it correctly generates KEY_MUTE on AT Translated Set 2 keyboard input device and also turn on/of mute led. But when micmute key is pressed then, nothing happen. No key event is reported and also led is not turned on/off. On the other hand, when thinkpad_acpi.ko is loaded, then both buttons mute and micmute correctly generates input events; mute via AT keyboard and micmute via ThinkPad Extra Buttons. But led is not changed. When thinkpad_acpi.ko is loaded it turn off both leds (mute and micmute) and leds after pressing any of those buttons, leds are not turned on again. When thinkpad_acpi.ko is unloaded, then pressing mute button again start switching led on/off. So it seems that some init sequence of thinkpad_acpi.ko breaks mute led. And fini sequence of thinkpad_acpi.ko makes mute led working again. -- Pali Rohár pali.rohar@xxxxxxxxx ------------------------------------------------------------------------------ Check out the vibrant tech community on one of the world's most engaging tech sites, Slashdot.org! http://sdm.link/slashdot _______________________________________________ ibm-acpi-devel mailing list ibm-acpi-devel@xxxxxxxxxxxxxxxxxxxxx https://lists.sourceforge.net/lists/listinfo/ibm-acpi-devel
