21.04 black screen after suspend integrated GPU

cn flag

Did a clean install of 21.04. Screen is black when waking from suspend.

Edit - What I did so far:

nouveau.modeset=0 in grub

Tried with ASPM set to L1 and L1L0s

gdm3 to lightdm

Edit2 - Updating to kernel 5.13.1 worked. Now I'm praying that I can get the Tesla K80 working as well.

Edit3 - sudo add-apt-repository ppa:graphics-drivers/ppa then installing driver 465 did not yield error. Getting error from the driver during use though. It prevents the computer to sleep after launching a couple of app (sleep work if I don't do anything). :(

Edit4 (last) - Putting the axe on 21.04. I don't think 5.13.1 is compatible with nvidia's drivers yet. Going for 20.04 Kubuntu.

I had a similar issue with my Asus Zenbook 13 running Ubuntu 20.04. I didn't have any drivers listed in Software & Updates > Additional Drivers (as I didn't have a dedicated GPU).

I experimented further, nonetheless, and under the Developer Options tab I checked Pre-released updates (focal-proposed). After that I updated the system (sudo apt update && sudo apt upgrade -y) and just like that the suspend error was gone and so far I haven't come across any bugs after installing the proposed updates...

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.
