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 ?
eh
