I used to hibernate on my laptop whose disk is encrypted, under ubuntu 20.04, following the instruction given here and here (except that I didn’t manage to make it work before ubuntu 20.04 because of nvidia drivers issues…).
But for some times, it does not work anymore: at recovering, after I type my encryption password, it hangs forever…
I first problem that I have is that I don’t really know how to "debug" this issue…
Then I wonder if the problem could come from swap priority. When I compare to here, my priorities are in wrong order.
root@is241395:~# swapon NAME TYPE SIZE USED PRIO /swapfile file 40G 0B -3 /dev/dm-2 partition 980M 0B -2
Can my problem comes from this. How to update these priorities (I am not sure to understand the relation with the fstab)?
