Black screen after login for more than one minute

I have two accounts on a device. I logged out of one and logged into the other. Now I see a black screen. It’s been like this for more than a couple minutes. Will hard restart but just leaving a paper trail.

Worked after physical restart but like I said just leaving a paper trail.

Happened again. I clicked switch user, locked into my account, splash screen showed up and then black screen again.

Is there any distro that has great defaults? One which uses Ctrl and not Alt for switching tabs? One that doesn’t install browser bookmarks. One that I can maximize windows with the Super + Up shortcut?
