Second monitor is repeatingly blank and activated again. At the bottom it probably contains the upper part of the first monitor. I had the same problem at 18.04 when using gdm3 without wayland during logon. [ Test case ] - Run gnome-shell with multimonitor - No flashing should happen on gdm initialization Also we should monitor crashes in e.u.c [ Regression potential ] Low, the proposed fix is part of the current stable branch upstream and not changed in further revisions. -- ProblemType: CrashDistroRelease: Ubuntu 18.10 Package: gnome-shell 3.29.90-2ubuntu1 ProcVersionSignature: Ubuntu 4.17.0-9.10-generic 4.17.17 Uname: Linux 4.17.0-9-generic i686 ApportVersion: 2.20.10-0ubuntu9 Architecture: i386 AssertionMessage: double free or corruption (fasttop) CurrentDesktop: ubuntu:GNOME Date: Mon Sep 3 21:02:58 2018 DisplayManager: gdm3 ExecutablePath: /usr/bin/gnome-shell GsettingsChanges: b'org.gnome.desktop.interface' b'gtk-im-module' b"'gtk-im-context-simple'" ProcCmdline: /usr/bin/gnome-shell ProcEnviron: LANGUAGE=en_US:en PATH=(custom, no user) XDG_RUNTIME_DIR=<set> LANG=en_US.UTF-8 SHELL=/bin/bash Signal: 6SourcePackage: gnome-shell StacktraceTop: __libc_signal_restore_set (set=0xbfcd5e9c) at ../sysdeps/unix/sysv/linux/nptl-signals.h:80 __GI_raise (sig=6) at ../sysdeps/unix/sysv/linux/raise.c:48 __GI_abort () at abort.c:79 __libc_message (action=do_abort, fmt=<optimized out>) at ../sysdeps/posix/libc_fatal.c:181 malloc_printerr (str=str@entry=0xb6b437e8 "double free or corruption (fasttop)") at malloc.c:5350 Title: gnome-shell assert failure: double free or corruption (fasttop) UpgradeStatus: No upgrade log present (probably fresh install) UserGroups: adm cdrom dip lpadmin plugdev sambashare sudo To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/mutter/+bug/1790525/+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
