Black screen after i close the lid and reopen

Question

After I close the lid of the laptop it doesn't enter in suspend mode. This happened immediately after an update of Ubuntu 18.04. I use the setting suspends when the laptop lid is closed OFF until I find a solution.

Why it doesn't suspend mode work?

Solution

In Ubuntu 18.04 Gnome desktop, there’s no option in Settings utility for configuring laptop lid close actions. And Gnome Tweaks only offer a switch to enable/disable ‘Suspend when the laptop lid is closed.

Follow the steps:

• Open Terminal
• Paste the following command in the Terminal sudo gedit /etc/systemd/logind.conf
• Provide your system password if it asks.
• Now you need to find the line #HandleLidSwitch=suspend & uncomment it (Remove the # from the beginning).

• It will be like the below image:

• Save and exit the file.

• Now restart the Systemd service using the following command: systemctl restart systemd-logind.service

That's it, This method will fix your issue.

I did a new installation of ubuntu and the result is the same : suspend mode doesn't work. The login screen remains locked and i must press and hold the power button to restart the os.
