xset led 3 not working on Ubuntu 21.04

ph flag

update my ubuntu recent version 21.04, but now my external keyboard backlight is not working. Previously it was working using "xset led on" in terminal and it is working perfectly on Windows. I even reinstalled ubuntu, used "xset led on", "xset led 3" and even "xset led 1 to 32" but the problem is still there.
