I am running Fedora 42 with kernel 6.14.9 on a Samsung Galaxy Book Pro 360 (first generation). The keyboard backlight is not working and does not appear in /sys/class/led= s/. The Fn keys related to keyboard backlight do not trigger ACPI events either. Attempting to load the samsung_laptop kernel module fails with: modprobe: ERROR: could not insert 'samsung_laptop': No such device This suggests the device is not supported or not detected correctly by the = DMI table lookup used by the module. Attached is a tar.gz file with full system diagnostics including: - dmidecode - dmesg - journalctl - lsmod - lsusb / lspci - /sys/firmware/acpi/tables/DSDT if available Please advise if support for this model can be added or if there's any workaround.
