0 s: Enable the second external display
produces this log:
Aug 31 14:40:06 c89 kernel: [703995.721847] [drm] Reducing the compressed
framebuffer size. This may lead to less power savings than a non-reduced-size.
Try to increase stolen memory size if available in BIOS. 

13 s: you click Keep Changes
produces 4 of these after 4 s
Aug 31 14:40:11 c89 gnome-terminal-[19749]: Allocating size to GtkBox
0x49fbb5a10 without calling gtk_widget_get_preferred_width/height(). How does
the code know the size to allocate?   

24 s: all monitors go to black

32 s: thunderbolt logs

Mucking with Wayland windows makes it go down quickly
Doing nothing in a good state goes to reset, too, after 51 s or longer
