Gnome-Shell on Wayland Poweroff system menu button not working

[Carla Sella]

When I click on the system menu arrow and select the power off button, it highlights in orange but when clicked it does not power off, or ask to power off as expected.

In syslog I have these logs:

Sep 4 22:16:58 carla-XPS-8900 gnome-shell[1853]: JS ERROR: TypeError: this.systemMenu._onPowerOffClicked is not a function#012Extension<._onPowerOffClicked@/home/carla/.local/share/gnome-shell/extensions/suspend-button@laserb/extension.js:188:9#012wrapper@resource:

I have Ubuntu Artful Aardvark (development branch) with all updates installed.

Carla, does clicking the button twice help (like in bug 1683867)?

[Jean-Baptiste Lallement (jibel)]

From the log you have the "Suspend button" extension enabled. Maybe it is incompatible with the latest version of gnome-shell in Ubuntu. Can you try to disable it and tell us if it solves your problem?

Thanks.

Hi Guys,
Thanks for your help.
I solved the problem uninstalling the "Suspend button" extension (I had forgotten it was installed).

Thank you Carla for following-up. I'm closing this report and as usual don't hesitate to submit any bug you may find.
