I was able to reproduce this with kernel 5.0.0 too. Isn't it possible that this is not caused by the kernel? I don't think I had this issue back then - it's something more recent.

This doesn't happen if I suspend it manually by opening the system menu and pressing the suspend button. Suspension works flawlessly when it is triggered manually. When the system resumes from automatic suspension, the lock screen is visible but does not respond. It's frozen. A notification says something like "system will suspend shortly due to inactivity". It never goes away. The keyboard responds during this (at least for a while). The CAPS LOCK LED turns on and off as I press it (with no delay). Sometimes I can even switch to another TTY and kill the X server, which is why I'm reporting it against gnome-shell. When switching TTY is impossible, I use the "REISUB" combination to shut down. Either way, I always lose the running session. This is reproducible about 60% of the time. Eventually I ended up disabling it and relying only on manual suspension. # Additional information: 1) Ubuntu 20.04.2 LTS / Release: 20.04 2) gnome-shell 3.36.4-1ubuntu1~20.04.2 ProblemType: Bug DistroRelease: Ubuntu 20.04 Package: gnome-shell 3.36.4-1ubuntu1~20.04.2 ProcVersionSignature: Ubuntu 5.8.0-44.50~20.04.1-generic 5.8.18 Uname: Linux 5.8.0-44-generic x86_64 ApportVersion: 2.20.11-0ubuntu27.16 Architecture: amd64 CasperMD5CheckResult: skip CurrentDesktop: ubuntu:GNOME Date: Wed Mar 3 16:56:01 2021 DisplayManager: gdm3 InstallationDate: Installed on 2021-01-31 (31 days ago) InstallationMedia: Ubuntu 20.04.1 LTS "Focal Fossa" - Release amd64 (20200731) RelatedPackageVersions: mutter-common 3.36.7+git20201123-0.20.04.1 SourcePackage: gnome-shell UpgradeStatus: No upgrade log present (probably fresh install) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1917674/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
