How to enable discrete GPU in Lubuntu 21.04?

cn flag

I have DELL Inspiron 5520 laptop with Lubuntu 21.04 installed and working properly. This laptop has a normal GPU (Intel) and a discrete GPU (Radeon 7600m). When I ran the upgrade I noticed that Lubuntu recognized the discrete GPU and installed its drivers correctly. But the question is, how can I enable that discrete GPU (Radeon) for using specific apps and games in Lubuntu 21.04?

This works for me

DRI_PRIME=1 app_you_want_to_run_into_discrete

you can also add "DRI..." indicator inside the destination run box desktop icon too.

Edit: you can check this option works reading temperatures with lm-sensors

sudo apt-get install lm-sensors

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.
