Whenever I log in, my screen says "HDMI NO SIGNAL"

[Perzan]

This has not happened for me before. Usually the screen will show fine after I log in, but now I have to drag my cursor into the darkness of the problematic screen and make it dance until the signal is picked up.

Potentially related:
I recently tried to make a guest account with no password required. I set a temporary password and then executed something like `sudo passwd -d guest`. As expected, it didn't work (it makes sense because there was no option to do so in the "Users" configuration GUI). Anyway, I then just gave up on it and deleted the account. When I tried to log into my main account, the screen problem started to happen. I tried restarting, but no luck.

Is this still an issue?

You've given us no indication as to what release or flavour of Ubuntu you are using.
You've not indicated which version of the linux kernel you are using to boot from.

Marking as "Incomplete" awaiting further information.
