Description Jack 2018-01-11 11:50:59 UTC

When the only screen is disconnected (Sony Tv over HDMI), Gnome, both on Wayland and Xorg crashes causing X to restart (on both Wayland and Xorg).

System:
Micro PC with single Sony Tv monitor connected through HDMI
Ubuntu 17.10
gnome-shell version 3.26.2-0ubuntu0.1

Steps to reproduce:
1. Start computer and log in (also started playing music)
2. Power off (at wall) / disconnect screen

3. Reconnect monitor

Expected result:
User should remain logged in (and music should continue to play)

Observed result:
Music stops as soon as monitor is disconnected. When monitor is reconnected, login screen is presented.

Tested on "Ubuntu", "Ubuntu on Xorg" and "Ubuntu Unity". "Ubuntu Unity" did not have the issue.

It looks like Ubuntu's dash extension is to blame for this - can you reproduce the issue in a regular GNOME session?

Comment 2 Jack 2018-01-11 16:16:35 UTC

Ah. Indeed it is. Installing vanilla Gnome and running that fixed the issue. Apologies.

Comment 3 Florian Müllner 2018-01-11 16:35:22 UTC

Thanks for checking. Closing as a downstream bug then.
