Screen Turning Off When Idle Even with Power Settings Disabled: A Troubleshooting Guide

Are you experiencing a frustrating issue where your screen turns off when idle, despite having power settings disabled? You're not alone. This problem has been reported by many users, especially those running Ubuntu 17.10 with the Gnome desktop environment. In this article, we'll delve into the possible causes and provide step-by-step solutions to help you resolve this issue.

When your screen turns off when idle, it's usually due to the system's power management settings. However, in your case, you've already disabled the power settings, which should prevent this behavior. So, what's going on? There are a few possible explanations:

Caffeine extension not working: You've mentioned that the Caffeine extension, which is designed to prevent screens from turning off, is not working. This could be due to a conflict with other extensions or a bug in the extension itself.
Blank screen disabled, but not working: You've also mentioned that you've disabled the Blank screen option, but it's still not working. This could be due to a misconfiguration or a bug in the Gnome settings.
Recent behavior change: You've noticed that this issue has started recently, which suggests that there might be a change in your system's configuration or a new software installation that's causing the problem.

To resolve this issue, let's go through some troubleshooting steps:

Step 1: Check for Conflicting Extensions

If you're using the Caffeine extension, try disabling it and see if the issue persists. You can also try removing the extension and reinstalling it to see if that resolves the issue.

Step 2: Re-enable Blank Screen Option

Try re-enabling the Blank screen option and see if that resolves the issue. You can do this by going to the Gnome settings, clicking on the "Power" option, and then selecting the "Blank screen" option.

Step 3: Check for System Updates

Make sure your system is up-to-date by running the following command in the terminal:

sudo apt update && sudo apt full-upgrade

This will update all the packages on your system, including the Gnome desktop environment.

Step 4: Disable Power Management

Try disabling power management altogether by running the following command in the terminal:

sudo systemctl stop systemd-logind

This will disable the systemd-logind service, which is responsible for managing power settings.

Step 5: Check for Conflicting Software

Try removing any recently installed software that might be causing the issue. You can do this by running the following command in the terminal:

sudo apt autoremove

This will remove any unnecessary packages that might be causing conflicts.

Step 6: Reboot Your System

Try rebooting your system to see if that resolves the issue.

If none of the above steps resolve the issue, you might need to try some more advanced troubleshooting steps:

Step 1: Check for Gnome Settings Corruption

Try resetting the Gnome settings to their default values by running the following command in the terminal:

sudo gnome-tweak-tool --reset

This will reset all the Gnome settings to their default values.

Step 2: Check for Systemd Configuration

Try checking the systemd configuration files to see if there are any issues. You can do this by running the following command in the terminal:

sudo systemctl status systemd-logind

This will show you the status of the systemd-logind service.

Step 3: Check for Kernel Configuration

Try checking the kernel configuration files to see if there are any issues. You can do this by running the following command in the terminal:

sudo cat /proc/cmdline

This will show you the kernel command line.

Screen turning off when idle, even with power settings disabled, can be a frustrating issue. However, by following the troubleshooting steps outlined in this article, you should be able to resolve the issue. Remember to check for conflicting extensions, re-enable the Blank screen option, check for system updates, disable power management, check for conflicting software, and reboot your system. If none of these steps resolve the issue, you might need to try some more advanced troubleshooting steps, such as checking for Gnome settings corruption, systemd configuration, and kernel configuration. Good luck!
