[Desktop-packages] [Bug 1734044] Re: gnome-shell crashes when monitor turned off or switch kvm [meta_monitor_manager_get_logical_monitor_from_number: assertion '(unsigned int) number < g_list_length (
This bug was reported for Ubuntu Desktop 17.10. I would like to add that the problem when disconnecting the only monitor also occurs when using Ubuntu Desktop 18.04 LTS (latest updates Jul19,2018). gnome-shell will not always crash but the desktop becomes unusable when using x11vnc. The new report#1782573 is already marked as a duplicate. https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1782573 https://www.dropbox.com/s/a8jjnw14uhtibzk/ubuntu1804-x11vnc- disconnected-monitor-fatal.mp4?dl=0 -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-shell in Ubuntu. https://bugs.launchpad.net/bugs/1734044 Title: gnome-shell crashes when monitor turned off or switch kvm [meta_monitor_manager_get_logical_monitor_from_number: assertion '(unsigned int) number < g_list_length (manager->logical_monitors)' failed] Status in GNOME Shell: Fix Released Status in gnome-shell package in Ubuntu: Incomplete Bug description: Gnome shell will crash every time when I turn off monitor or switch the kvm to my other system.

[Desktop-packages] [Bug 1782573] [NEW] Remote X11vnc session unusable due to crash in gnome-shell when disconnecting HDMI monitor under Ubuntu Desktop 18.04 LTS
Public bug reported:
Expect to happen: I can use X11VNC when the monitor is disconnected.
What happens instead: remote X11vnc session unusable due to crash in
gnome-shell when disconnecting HDMI monitor under Ubuntu Desktop 18.04
LTS
I'm using a stable system that works fine when the monitor is connected;
also X11VNC works fine.
But I want to access the GUI remotely via X11VNC when the HDMI monitor
is disconnected then the system is not usable (lots of gnome-shell
errors in syslog) and sometimes the gnome-shell will also segfault (the
segfault is not in this bugreport). The X11 remote viewer is full of
clutter (see screencast).
Please see below for the syslog entries when disconnecting the monitor
with no X11VNC active, and the syslog entries when the monitor is
disconnected and starting X11VNC.

[ Test Case ] Requires a GeForce 6150SE or similar integrated GPU from nVidia. Problem manifests immediately on login. [ Regression Potential ] The fix involves a specific hardware blacklist. Anticipated regressions include fixed support for the specific hard in future nVidia driver releases and potentially additional unidentified hardware affected by this bug needing to be added to the blacklist. Note that there is a manual workaround to the problem consisting of disabling the X11 Sync feature through CCSM. [ Other Info ] This fix was cherry-picked from the Ubuntu Vivid Vervet development release where it has been in regular use for some weeks.
