I used turned on my keyboard backlight by entering xset led named "Scroll Lock" in terminal till two days ago. But now it doesn't work... backlight is not turning on! (I mean I cannot turn on my keyboard light with this code.)

But the keyboard works perfectly fine on my windows laptop...!

Fn+Sl also doesn't work!

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
