Getting suspend to work on Ubuntu (21.10 - impish release)?

uz flag

I turned off secure boot and installed ubuntu.

Everything was wiped and installation went fine.

I am using an aero 15x v8 laptop. Version 21.10 of Ubuntu.

Then I turned secure boot back on but it doesn't resume after I suspend (close the lid, or it idles for too long).

I'm not sure how to fix it.

I bought a book on linux but it is 500 pages and it will take me some time to get through it.

Is there something I missed?

Is suspend not working *only* after secure boot is turned on? In other words, does it work correctly with secure boot turned on? Make that very clear in your question. If that is the case, the workaround is easy: keep secure boot turned off.

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.
