Well, the problem I have ocurrs randomly and I saw it in Ubuntu 17.10 and 18.04. In the prior version I get the typical “stopping user manager for uid” message, but in the most recent version I only see some information about storage I always see in the system boot, nothing apparently bad. I always use the official NVIDIA blob driver from the Proprietary GPU Drivers PPA, but the I also saw the bug in drivers provided by Ubuntu’s repositories. I used Linux Mint 19 for one month and I didn’t see the bug, so I think that origin is from Ubuntu’s stack. I suspect of two components and three possibilities: -GDM. -NVIDIA Prime. -Both combinanted. I’m trying a workaround setting nomodeset in the file “/etc/default/grub”. The line: ----- GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" ----- Is now: ----- GRUB_CMDLINE_LINUX_DEFAULT="quiet splash nomodeset" ----- After modify the file I executed the “sudo update-grub” command. Until now I didn’t see the bug again, but it’s too early to make sure. If I don’t see the bug again in two months I will declare the bug solved for me, but this is not the "out of the box" behavior you expect from a system like Ubuntu. Sorry if my English is hard to understand. --- ProblemType: Bug ApportVersion: 2.20.9-0ubuntu7.2 Architecture: amd64 CurrentDesktop: communitheme:ubuntu:GNOME DisplayManager: gdm3 DistroRelease: Ubuntu 18.04 GsettingsChanges: b'org.gnome.shell' b'had-bluetooth-devices-setup' b'true' b'org.gnome.shell' b'favorite-apps' redacted by apport b'org.gnome.desktop.interface' b'gtk-im-module' b"'gtk-im-context-simple'" InstallationDate: Installed on 2018-07-26 (14 days ago) InstallationMedia: Ubuntu 18.04.1 LTS "Bionic Beaver" - Release amd64 (20180725) NonfreeKernelModules: nvidia_modeset nvidia Package: gnome-shell 3.28.2-0ubuntu0.18.04.1 PackageArchitecture: amd64 ProcEnviron: TERM=xterm-256color PATH=(custom, no user) XDG_RUNTIME_DIR=<set> LANG=es_ES.UTF-8 SHELL=/bin/bash ProcVersionSignature: Ubuntu 4.15.0-30.32-generic 4.15.18 Tags: bionic Uname: Linux 4.15.0-30-generic x86_64 UpgradeStatus: No upgrade log present (probably fresh install) UserGroups: adm cdrom dip lpadmin plugdev sambashare sudo _MarkForUpload: True To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1785834/+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
