Accessing the leave dialogue


Is there a keyboard shortcut?

If not, can there be one?

Whilst I can not see a matching action in lumina-config (Desktop Settings), two days ago I did somehow get the dialogue whilst working with Lumina without a GUI (limited to the desktop background alone … I thrashed around, blindly, until the dialogue appeared but it was so thrashy that I could not tell what led to its appearance).

Graphics (display/screen rendering, DRI, DRM etc.) with and without vendor-specific drivers

There is no keyboard shortcut to open that dialog at the moment.
There will be eventually (been on my list).
