When I connect my EliteBook to my Dock and Daisy Chain USB-C cable, sometimes there are issues with the screens coming on.
Historically I’ve just tended to restart, but you don’t need to, you can just restart the display manager, as below.
$ sudo systemctl restart display-manager
This will log you out, so it’s almost as inconvenient as a restart, but it tends to fix any issues I’m having.
I'm a technology professional who's been passionate about computers since my Grandad introduced me to an Intel 386 back in the 90s when I was a kid. Those moments inspired a passion within for technology, and I've been playing around with anything with a circuit board ever since. Whenever I have a moment you can probably find me working on something computer-related, and this is where I like to write about those moments.
