With the current kernel do you have any errors or is anything not working?

Not now but when I installed ubuntu some months ago then I was having graphics issue, and someone on reddit suggested that generic kernel is too old for your hardware and you should upgrade the kernel to by `sudo apt install linux-oem-20.04d`. So I thought just after installing kubuntu of doing that, but thought it would be better to ask to someone who knows the stuff.

If you have no errors I would not be changing the kernel. As for video issues maybe a kernel or maybe a different driver would be needed.

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.
