on my laptop, upon closing the lid and opening it, the computer screen goes black, i know the system is still powered on as the power button is blue and the screen is actually projecting a black background, but i can't do anything to get to the login screen or desktop . I mean, is it locked to a certain key or sm ? I have already tried turning off screen timeout by setting it to never, however this has stopped working.
Can you launch terminal and run
sudo nano /etc/systemd/logind.conf
Arrow key down to the line
Change this in both of two ways: remove the hashtag
# and change
ctl+o to overwrite, then tap
enter to save current configuration. Tap
ctl+x to exit the editor.
Reboot... and test. Please relay the results.
yup, this worked perfectly, cheers!
