I had the same issue with Ubuntu 18.40 (final Beta) and HP EliteBook 850 G5 and reported the bug 1762814 and the solution (or rather workaround) for me was to blacklist amdgpu and this gnome shell crash, all the boot errors and suspend issues were gone.
How to blacklist amdgpu is described here: https://unix.stackexchange.com/questions/360709/how-to-blacklist-amdgpu sudo vi /etc/modprobe.d/blacklist.conf ... blacklist amdgpu ... sudo update-initramfs -u I've as well made my comment on this here: https://askubuntu.com/questions/769581/ubuntu-16-04-not-waking-up-after- suspend-on-hp-elitebook-8440-and-spamming-kern/1023798#1023798 -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gnome-shell in Ubuntu. https://bugs.launchpad.net/bugs/1748450 Title: gnome-shell crashed with SIGTRAP in _g_log_abort() from g_log_default_handler() from default_log_handler(message="Connection to xwayland lost") from g_logv() from g_log() from <bug 1505409> To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1748450/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
