It should start with no issues [ Regression potential ] We were deferencing a NULL pointer while outputting an error. This is pretty safe. Although the session might still not run properly as per a driver issue to be addressed in linux package. --- https://gitlab.gnome.org/GNOME/mutter/issues/70 https://errors.ubuntu.com/problem/16426125ad8d92ae4dc9ce9e89450153b0a8b665 https://salsa.debian.org/gnome-team/mutter/merge_requests/6 --- The crash was reported after booting and logging in to an X.Org session. $ lsb_release -rd Description: Ubuntu Bionic Beaver (development branch) Release: 18.04 $ apt-cache policy gnome-shell gnome-shell: Instalovaná verze: 3.27.92-0ubuntu1 Kandidát: 3.27.92-0ubuntu1 Tabulka verzí: *** 3.27.92-0ubuntu1 500 500 http://de.archive.ubuntu.com/ubuntu bionic/main amd64 Packages 100 /var/lib/dpkg/status ProblemType: CrashDistroRelease: Ubuntu 18.04 Package: gnome-shell 3.27.92-0ubuntu1 ProcVersionSignature: Ubuntu 4.15.0-10.11-generic 4.15.3 Uname: Linux 4.15.0-10-generic x86_64 NonfreeKernelModules: wl ApportVersion: 2.20.8-0ubuntu10 Architecture: amd64 CurrentDesktop: GNOME-Greeter:GNOME Date: Sun Mar 11 11:08:00 2018 DisplayManager: gdm3 ExecutablePath: /usr/bin/gnome-shell GsettingsChanges: InstallationDate: Installed on 2017-12-19 (81 days ago) InstallationMedia: Ubuntu 17.10 "Artful Aardvark" - Release amd64 (20171018) ProcCmdline: /usr/bin/gnome-shell ProcEnviron: LANGUAGE=cs_CZ PATH=(custom, no user) XDG_RUNTIME_DIR=<set> LANG=cs_CZ.UTF-8 SHELL=/bin/false SegvAnalysis: Segfault happened at: 0x7f3fee5d2f17 <meta_gpu_kms_apply_crtc_mode+215>: mov 0x20(%rax),%rcx PC (0x7f3fee5d2f17) ok source "0x20(%rax)" (0x00000020) not located in a known VMA region (needed readable region)! destination "%rcx" ok SegvReason: reading NULL VMASignal: 11SourcePackage: gnome-shell StacktraceTop: meta_gpu_kms_apply_crtc_mode () at /usr/lib/x86_64-linux-gnu/libmutter-2.so.0 meta_renderer_native_finish_frame () at /usr/lib/x86_64-linux-gnu/libmutter-2.so.0 () at /usr/lib/x86_64-linux-gnu/mutter/libmutter-clutter-2.so () at /usr/lib/x86_64-linux-gnu/mutter/libmutter-clutter-2.so () at /usr/lib/x86_64-linux-gnu/mutter/libmutter-clutter-2.so Title: gnome-shell crashed with SIGSEGV in meta_gpu_kms_apply_crtc_mode() UpgradeStatus: Upgraded to bionic on 2018-03-05 (5 days ago) UserGroups: To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1754949/+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
