I've tried all Fn+F combinations. They mostly work. "Reader mode" combo Fn+F9 doesn't have any effect for me, Ubuntu 26.04 Gnome shell. "Fn+F7" External display toggle doesn't make any difference to me too. Also, I've checked `fan_mode` default value & changing it: $ sudo cat /sys/devices/platform/lg-laptop/fan_mode 0 $ echo 1 | sudo tee /sys/devices/platform/lg-laptop/fan_mode # should disab= le LG fan silent mode? Is it correct, by the way? 1 $ sudo cat /sys/devices/platform/lg-laptop/fan_mode 1 Loading driver + keys testing dmesg logs: ``` [ 7437.824922] ACPI Error: No handler for Region [XIN1] (000000006c907335) [UserDefinedRegion] (20251212/evregion-131) [ 7437.824931] ACPI Error: Region UserDefinedRegion (ID=3D143) has no handl= er (20251212/exfldio-261) [ 7437.824935]=20 Initialized Local Variables for Method [_TMP]: [ 7437.824936] Local0: 0000000056306aad Integer 0000000000000024 [ 7437.824940] No Arguments are initialized for method [_TMP] [ 7437.824942] ACPI Error: Aborting method \_SB.PC00.LPCB.LGEC.SEN2._TMP du= e to previous error (AE_NOT_EXIST) (20251212/psparse-529) [ 7441.231104] lg_laptop: loading out-of-tree module taints kernel.
