I've just upgraded from Ubuntu 23.10 to 24.04 and realized that everytime I disconnect the external monitor (HDMI), the Gnome session ends abruptly and the login screen is shown. On Ubuntu 23.10 that didn´t use to happen.

I'm using wayland.

All opened apps are killed too.

How to reproduce:

  1. Start graphical user session (login) with external monitor connected
  2. Disconnect HDMI cable

Does anyone know how to fix it?

Regards

I was having the same problem.

It seems to be a problem with the Ubuntu tiling assistant extension and/or the library mutter. I've found a discussion about it here.

As presented in the bug report, there are two steps to solve it:

  1. Disable the "Ubuntu tiling assistant" extension.
  2. Install manually an update of mutter from 46.0 to 46.1. To do so (still from here):

wget https://launchpad.net/ubuntu/+source/mutter/46.1-2ubuntu1/+build/28374184/+files/gir1.2-mutter-14_46.1-2ubuntu1_amd64.deb https://launchpad.net/ubuntu/+source/mutter/46.1-2ubuntu1/+build/28374184/+files/libmutter-14-0_46.1-2ubuntu1_amd64.deb https://launchpad.net/ubuntu/+source/mutter/46.1-2ubuntu1/+build/28374184/+files/mutter-common-bin_46.1-2ubuntu1_amd64.deb https://launchpad.net/ubuntu/+source/mutter/46.1-2ubuntu1/+build/28374184/+files/mutter-common_46.1-2ubuntu1_all.deb

sudo dpkg -i *.deb

Log in again or reboot.

I've just disabled the "Ubuntu tiling assistant" extension, and it seems to work fine for me.

I don't know if there is some side effect of manually installing the mutter update.

For me, the issue was a Pano - Clipboard Manager gnome extension. https://extensions.gnome.org/extension/5278/pano/

I had the pre-release version from github: https://github.com/oae/gnome-shell-pano/releases/tag/v23-alpha

After removing it, the issue is gone.
