You mean just suspend as in 'sleep'? Like closing the lid on a macbook. I am doing that with the regular framework 13 (same amd though) multiple times a day.
I think it’s very valid. I want to be hardware-independent, not only OS independent. I need graphene to work on a fairphone, jolla phone or whatever other alternatives there are. E/os can do that (to an extent), Graphene can’t for probably very good reason, but still: It‘s not an alternative then.
