Ubuntu 20.04.2 LTS freezes after being suspend

mc flag

The issue happened all of a sudden without any new software installation or updates (to my knowledge).

After I try to wake up the computer I get a white cursor on the screen and when I press CTRL + ALT + F7 I can see the following output:

/dev/nvme0n1p6: recovering journal
/dev/nvme0n1p6: Clearing orphaned inode 3019465 (uid=1000, gid=1000, mode=010060
...
...
/dev/nvme0n1p6: clean, 2591309/12058624 files, 26099507/48227072 blocks

I already tried setting GRUB_CMDLINE_LINUX in /etc/default/grub to both nouveau.blacklist=1 and nouveau.modeset=0. Neither worked.

Ubuntu 20.04.2 LTS

Do you have multiple monitors? I have similar behavior sometimes, using Asus notebook with external monitor connected. As a temporary workarround, try disconnect secondary monitor before computer suspends.

@MauricioID yes, I'm using the exact same setup as you - a laptop with an external monitor. I just managed to solve the issue by moving to nvidia-driver-450.

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.
