--- Comment #1 from [email protected] --- 1. The kernel LED state is correctly updated: - /sys/class/leds/input32::capslock/brightness correctly shows 1/0 - Verified with: cat /sys/class/leds/input32::capslock/brightness 2. Writing to sysfs succeeds but doesn't update the physical LED: - echo 1 > /sys/class/leds/input32::capslock/brightness (no error) - Kernel state changes but LED remains off 3. Device identification: - Event device: /dev/input/event23 - Vendor ID: 16d0 - Model ID: 0d3c - HID device: /dev/hidraw16 4. Hypothesis: MX Keys uses Logitech HID++ protocol for LED control, which KDE Wayland compositor doesn't implement. The keyboard firmware doesn't respond to standard Linux LED control mechanisms. -- You are receiving this mail because: You are watching all bug changes.
