Some Screen Problem

  • 772

first time here! I'm having a problem and I need HELP

I installed an add-on to dim my screen for the night, but the result was not so satisfying, the screen went automatically black, no way of seeing anything.

Then anytime I try to login to my user, the add-on is already running and I can't see anything, so no use for my Ubuntu anymore. Ofc, silly me, I don't remember the name of the add-on either, so I can't even search it with the "apt-cache search" command in the recovery boot. Well, I tried to search "dimmer" and "dimme", that had no result, and "dim", which had so many results I couldn't find anything useful.

Anyone have an idea about how to fix this without having to reinstall the entire Ubuntu?

    Assuming that you're running Ubuntu 18.04 or newer...

    • turn on the computer
    • at the GRUB menu, choose Additional Options
    • choose Recovery Mode, then Root Access
    • at the # prompt, type:
    dpkg -l *redshift*

dpkg -l *lux*

    If you get an answer to either one of the above commands, note the name of the application, then type:

    sudo apt-get purge enter-application-name-here

ie: sudo apt-get purge redshift

    If you don't get an answer to one of the above commands, then type:

    ls -al /home/enter-your-username-here/.local/share/gnome-shell/extensions

    And report that output back to me as an edit to your question, and I'll tell you the next step.
