Screen Brightness reset issue

nr flag

I have a brand new lenovo 5 pro laptop with Windows 10 + Ubuntu 20.04 dual boot installation, and I am facing a weird issue. Every time my screen sleeps and locks due to inactivity, and when I unlock it again, the screen brightness resets to maximum. When I move the brightness slider, the brightness adjusts to the corresponding level of the slider. This only happens during screen sleep, lock and unlock cycle. Does not happen after suspend, restart or hibernate. All the solutions I found pertained to Ubuntu 12.04 or thereabout. Not sure what to do here.

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.
