The > sysfs interface `asus::kbd_backlight` is completely missing from > `/sys/class/leds/`. >=20 > The keyboard and touchpad are driven by a PixArt I2C-HID controller > recognized as `ASUP1200:00` (HID ID 093A:200A). The kernel correctly > registers the keyboard functions via i2c-hid, but does not expose any > LampArray or LED brightness interfaces. >=20 > Attempts made: > - Upgraded laptop BIOS to the latest version. > - Tested OpenRGB and VRGB (devices not found because hidraw/sysfs endpoin= ts > are missing). > - Loaded i2c-dev and verified Intel SMBus i801 adapter is fully active. > - Attempted to pass `acpi_osi=3D"Windows 2020"` and `i2c_hid.polling_mode= =3D0` > in GRUB parameters, but the HID interface for LEDs remains hidden. >=20 > I am attaching the acpidump, fastfetch summary, dmesg logs, and dmidecode > details in a compressed archive. >=20 > Cross-reference: Tracking this issue on ASUS-Linux GitLab at > https://gitlab.com=20 Errata corrige for Asus-Linux Gitlab link: https://gitlab.com/asus-linux/linux-g14/-/work_items/18 --=20 You may reply to this email to add a comment.
