I'll add a summary of what was told in the anwser : I have the latest BIOS on the Lenovo webpage, this bug appears for both (Linux) and neither on Win10.
- xev detects any Fn-Fx combination, apart from Fn-F6 (touchpad toggle). It doesn't detect Fn alone - dmesg does not print any error linked with me pressing Fn-F6 - "Ideapad extra buttons" is listed both in /proc/bus/input/devices and in xinput --list - File named /sys/devices/platform/ideapad/touchpad in the documentation appears to be /sys/devices/pci0000:00/0000:00:1f.0/PNP0C09:00/VPC2004:00/touchpad on my computer. Its content is always 1 regardless of the setting in Kubuntu or me pressing Fn-F6 - File /sys/kernel/debug/ideapad/status is always ``` Backlight max: 21 Backlight now: 17 BL power value: On ===================== Radio status: On(1) Wifi status: Off(0) BT status: Off(0) 3G status: Off(0) ===================== Touchpad status:On(1) Camera status: Off(0) ===================== Conservation mode: Off(268829184) ``` regardless of regardless of the setting in Kubuntu or me pressing Fn-F6 (touchpad status) or even me changing the luminosity, toggling Wifi, etc. - evtest results : + F1 through F12 show the corresponding keycode. + On its own, Fn does not appear at all. + Fn-F1 (mute) shows MSC_SCAN value a0, keycode 113 (KEY_MUTE) with values alternating 1-0 (as I press/release, this will be the same) + Fn-F2 (vol down) and Fn-F3 (vol up) show MSC_SCAN values ae and b0, with keycodes 114 (KEY_VOLUMEDOWN) and 114 (KEY_VOLUMEUP) + Fn-F4 (mute mic) does not appear at all (it works well though) + Fn-F5 (reload) appears as F5 + Fn-F6 (touchpad switch) does not appear at all (and doesn't work) + Fn-F7 (airplane mode) does not appear at all (but works) + Fn-F8 (cut camera, I guess?) does not appear at all (doesn't work? I haven't found its use, but when streaming my webcam to VLC, it did nothing) + Fn-F9 (lock) appears as LEFTMETA-L, where releasing F9 releases L and Fn releases LEFTMETA + Fn-F10 (change multiscreen options) appears as LEFTMETA-P where repressing F10 represses P and releasing Fn releases LEFTMETA + Fn-F11 (luminosity down) and Fn-F12 (luminosity up) do not appear at all (but work well though) - acpi_listen results: + Fn-F1: button/mute MUTE 00000080 00000000 K + Fn-F2: button/volumedown VOLDN 00000080 00000000 K + Fn-F3: button/volumeup VOLUP 00000080 00000000 K + Fn-F4: button/f20 F20 00000080 00000000 K + Fn-F5: ^[[15~ (not acpi_listen, but the same code as F5 in console) + Fn-F[6-10]: + Fn-F11: video/brightnessdown BRTDN 00000087 00000000 + Fn-F12: video/brightnessup BRTUP 00000086 00000000 -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1885033 Title: Touchpad switch not working (Lenovo IdeaPad L340-15IRH, Kubuntu 20.04) Status in linux package in Ubuntu: Incomplete Bug description: The touchpad switch, Fn-F6, does not work for me.
