Ubuntu flashing screan on power off and turn on after suspend

lk flag

I installed ubuntu 20.04 on my Dell Studio 1555 laptop and It flashes two or three times when I try to turn it off and when It woke up after suspend. I had this problem with older versions of Ubuntu and even Kali linux

Here you can see what happens

If it works fine other than those 2 seconds then not really a problem or is it? Be glad that such old machine still works and have decent support with Linux.

@ChanganAuto Yes, but my laptop easily runs all Windows versions so my question came up as to why it should flashing in Linux

It has an old graphics that never had the "love" it deserved from the Linux AMD graphics drivers. Initially, and for a few years after, it was supported by proprietary drivers. Then AMD moved to make all their graphics drivers open-source and by that time this chip was already old. So, the family of drivers that has been used since that time focused mostly on newer chips.

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.
