Is there an equivalent to Win + Ctrl + Shift + B on Ubuntu/Linux ? (lemmy.world)

I'm using Ubuntu on my Dell XPS 17, connected to a Dell Dock via USB-C, that has 2 monitors connected with Displayport. Sometimes on signal acquisition, screens remain black, and I have to lock the session (Win + L), wait a few seconds, then wake up the laptop, so signal may or may not be correctly acquired (otherwise I'd do it again until it works)

On Windows, there's this shortcut, Win + Ctrl + Shift + B, that acts as if the screen were disconnected/reconnected. It may help with my signal acquisition problem. Is there an equivalent on Ubuntu/Linux, please ?

The [Super]+[P] combo might be useful. This is for display switching, it should rotate between:

internal only
external only
extend display
duplicate display
display off (all)

On KDE you can hold down [Super] and rotate through the options by tapping [P]. I'm not sure how this is normally configured on Unity/Gnome, it may require selecting an option with the arrow keys and then pressing [Enter].
