Hello list, I'm running a recent linux kernel (v5.1.2) on a Lenovo X380 Yoga with the thinkpad_acpi kernel module active: bash-4.4# dmesg | grep think [ 1.912994] thinkpad_acpi: ThinkPad ACPI Extras v0.26 [ 1.913000] thinkpad_acpi: http://ibm-acpi.sf.net/ [ 1.913003] thinkpad_acpi: ThinkPad BIOS R0SET39W (1.23 ), EC unknown [ 1.913006] thinkpad_acpi: Lenovo ThinkPad X380 Yoga, model 20LJS43M00 [ 1.913506] thinkpad_acpi: radio switch found; radios are enabled [ 1.913571] thinkpad_acpi: Tablet mode switch found (type: GMMS), currently in laptop mode [ 1.913801] thinkpad_acpi: This ThinkPad has standard ACPI backlight brightness control, supported by the ACPI video driver [ 1.913808] thinkpad_acpi: Disabling thinkpad-acpi brightness events by default... [ 1.916093] thinkpad_acpi: rfkill switch tpacpi_bluetooth_sw: radio is unblocked [ 1.921443] thinkpad_acpi: Standard ACPI backlight interface available, not loading native one [ 1.921451] thinkpad_acpi: volume: disabled as there is no ALSA support in this kernel [ 1.926063] thinkpad_acpi: battery 1 registered (start 128, stop 128) [ 1.926126] input: ThinkPad Extra Buttons as /devices/platform/thinkpad_acpi/input/input7 [ 130.702563] thinkpad_acpi: setting the hotkey mask to 0xffffffff is likely not the best way to go about it [ 130.702568] thinkpad_acpi: please consider using the driver defaults, and refer to up-to-date thinkpad-acpi documentation [ 130.703930] thinkpad_acpi: asked for hotkey mask 0xffffffff, but firmware forced it to 0xfffffffb My problem is, that the state of the tablet mode switch - which can be determined by reading /sys/bus/platform/drivers/thinkpad_acpi/thinkpad_acpi/hotkey_tablet_mode - never changes, no matter how far I open or close the Yoga's lid. Also, in a dual boot setup (Windows 10 / Linux), when I switch the Yoga to tablet mode in Windows, reboot it in this state to linux and then "fold" it back to laptop mode, the "hotkey_tablet_mode" still tells me that the Yoga is in tablet mode (which means that the keyboard does not work...); and I did not find any way to switch it back to laptop mode under linux. Only after booting Windows again and rebooting in laptop mode, hotkey_tablet_mode holds the correct value. I suppose that there's something wrong with my kernel config, but I have no clue what... Maybe someone can give me a hint? Thanks and best regards, Christian _______________________________________________ ibm-acpi-devel mailing list ibm-acpi-devel@xxxxxxxxxxxxxxxxxxxxx https://lists.sourceforge.net/lists/listinfo/ibm-acpi-devel
