Thanks for pointing out uninstalling the shell extensions. I had the same problem and switching off all custom shell extensions helped instantly.
Basically, this also urges an audit of gnome-shell and associated libraries, as this type of crash _could_ be a security issue triggered by extensions (potentially untrusted thris party data/code). -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-shell in Ubuntu. https://bugs.launchpad.net/bugs/1797141 Title: [nvidia] gnome-shell frequent restart or crash after unlocking screen or resume from sleep Status in gnome-shell package in Ubuntu: Expired Bug description: First, let me provide necessary information about system or packages System: Ubuntu 18.04.1 LTS Package version: gnome-shell 3.28.3-0ubuntu0.18.04.2 The problem started 3-4 weeks ago (probably after updating several packages via `apt update; apt upgrade` After *almost all* screen unlock or resume from sleep events, this is what happens: * I briefly see the desktop screen (which is security or privacy problem I guess) * then login screen comes up, asking for the password * after I put the password there is a wait (5-10 seconds) * after that there are two possibilities: 1. there's brief flash in screen and then screen goes black. i can not fire up tty consoles and i have to use SysRq Magic keys to reboot the system 2. if it does not crash, I login the system, I see the programs/windows but they're unresponsive for 10-30 seconds. after unresponsive time, gnome-shell restarts and only then system starts to function normally. Then apport-bug is started for gnome-shell, I try to send the crash reports. I'm not sure this is gnome-shell or gdm3 or Xorg problem. But, apport- crash always starts collecting data about gnome-shell, thus I filed report against gnome-shell. I also filed bug report against xorg (https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1797124). Let me provide additional info that might help; - I have nvidia drivers installed in system - gnome-shell produces tons of journal entries (this apport-crash reports are huge, nearly 150 MB and I cannot upload them) ProblemType: Bug DistroRelease: Ubuntu 18.04 Package: gnome-shell 3.28.3-0ubuntu0.18.04.2 ProcVersionSignature: Ubuntu 4.15.0-36.39-generic 4.15.18 Uname: Linux 4.15.0-36-generic x86_64 NonfreeKernelModules: nvidia_modeset nvidia ApportVersion: 2.20.9-0ubuntu7.4 Architecture: amd64 CurrentDesktop: GNOME Date: Wed Oct 10 17:10:40 2018 DisplayManager: gdm3 InstallationDate: Installed on 2018-06-01 (131 days ago) InstallationMedia: Ubuntu 18.04 LTS "Bionic Beaver" - Release amd64 (20180426) 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/gnome-shell/+bug/1797141/+subscriptions -- Mailing list: https://launchpad.net/~desktop-packages Post to : desktop-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
