But then after reboot, the screen freezes in the middle of the boot process and I never get the login banner. I was able to launch the recovery mode and get some information through journalctl command and it seems that the problem is related to a Wayland server crash. I don't really know if the problem comes from Wayland or Gnome. The first worrying error message is : "gnome_shell[1165]: Failed to apply DRM plane transform 0: Permission non accordée" (ie, Permission denied in french) Thanks to the recovery mode I was able to upgrade via "apt-get update" and "apt-get upgrade", but the symptoms were the same after a reboot I uncommented the "Enable=true" flag of the [debug] section of /etc/gdm3/custom.conf and I provide and extract of the journalctl output related to the error as an attachment to this report (journalctl_extract.txt part). I also provide some system information (system.txt pat). I hope this may help to solve the issue. --- ProblemType: Bug ApportVersion: 2.20.10-0ubuntu27.1 Architecture: amd64 CurrentDesktop: ubuntu:GNOME DistroRelease: Ubuntu 19.04 InstallationDate: Installed on 2019-07-15 (2 days ago) InstallationMedia: Ubuntu 19.04 "Disco Dingo" - Release amd64 (20190416) Package: gdm3 3.32.0-1ubuntu1 PackageArchitecture: amd64 ProcEnviron: TERM=xterm-256color PATH=(custom, no user) XDG_RUNTIME_DIR=<set> LANG=fr_FR.UTF-8 SHELL=/bin/bash ProcVersionSignature: Ubuntu 5.0.0-20.21-generic 5.0.8 Tags: disco Uname: Linux 5.0.0-20-generic x86_64 UpgradeStatus: No upgrade log present (probably fresh install) UserGroups: adm cdrom dip lpadmin plugdev sambashare sudo _MarkForUpload: True mtime.conffile..etc.gdm3.custom.conf: 2019-07-18T07:25:10.575513 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg-server/+bug/1836805/+subscriptions -- Mailing list: https://launchpad.net/~desktop-packages Post to : [email protected] Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
