Package: gnome-shell
Version: 3.18.1-1
Severity: important
Dear Maintainer,
Each time I unplug an external screen from my computer, whether this screen was
plugged using VGA or HDMI, gnome-shell crashes immediately, putting me back to
TTY1. The only solution then is to restart gdm3 using '/etc/init.d/gdm3
restart'.
This bug sort of looks like Bug#818357, but not exactly as it first does not
concern a dock. I don't have anything printed in the console. And my system
does not freeze.
Looking at 'dmesg', I can see the following line each time it happens:
[ 269.643683] traps: gnome-shell[5493] trap int3 ip:7fab50a0a87b
sp:7ffe148df7e0 error:0
Doing 'journalctl -b -a', I can see the following that seem to relate to the
current error:
Mar 16 19:12:38 duck gnome-session[5485]: (gnome-settings-daemon:5538): Gdk-
ERROR **: The program 'gnome-settings-daemon' received an X Window System
error.
Mar 16 19:12:38 duck gnome-session[5485]: This probably reflects a bug in the
program.
Mar 16 19:12:38 duck gnome-session[5485]: The error was 'BadRROutput (invalid
Output parameter)'.
Mar 16 19:12:38 duck gnome-session[5485]: (Details: serial 226 error_code 147

Mar 16 19:12:38 duck gnome-session[5485]: (Note to programmers: normally, X
errors are reported asynchronously;
Mar 16 19:12:38 duck gnome-session[5485]: that is, you will receive the
error a while after causing it.
Mar 16 19:12:38 duck gnome-session[5485]: To debug your program, run it with
the GDK_SYNCHRONIZE environment
Mar 16 19:12:38 duck gnome-session[5485]: variable to change this behavior.
You can then get a meaningful
Mar 16 19:12:38 duck gnome-session[5485]: backtrace from your debugger if
you break on the gdk_x_error() function.)

This bug makes things difficult, as each time I need to use an external screen,
I know that when I'll unplug gnome will crashes.
I can provide more data on demand, as the bug is easily reproduced (I just need
to unplug my external screen...).
Thanks,
Raphaël
