Possible Causes of the Issue

There are several possible causes for the laptop display not turning on after waking up from suspend2ram on Linux. Let's take a look at some of the common causes:

• Graphics Driver Issue: Outdated or incompatible graphics drivers can prevent the display from turning on after waking up from suspend2ram.
• Power Management Settings: Incorrect power management settings can cause issues with waking up from suspend2ram.
• Kernel Bug: In some cases, a bug in the Linux kernel can be the cause of this problem.

Steps to Fix the Issue

Now that we know the possible causes of the problem, let's proceed with the troubleshooting steps to fix the laptop display not turning on after waking up from suspend2ram on Linux:

Step 1: Update Graphics Drivers

The first step is to update your graphics drivers to the latest version. Outdated or incompatible graphics drivers can often cause display issues. Follow these steps to update your graphics drivers:

1. Open a terminal by pressing Ctrl + Alt + T.
2. Type the following command and press Enter to update your package lists: sudo apt update
3. Next, type the following command and press Enter to upgrade your system: sudo apt upgrade
4. Reboot your laptop and check if the issue is resolved.

Step 2: Adjust Power Management Settings

If updating the graphics drivers didn't fix the issue, you can try adjusting the power management settings. Here's how:

1. Go to the system settings by clicking on the gear icon in the top right corner of your screen.
2. Select "Power" or "Power & Brightness" from the menu.
3. Adjust the settings to your preference, making sure that the "Blank Screen" and "Suspend" options are set to a reasonable time.
4. Save the changes and check if the issue is resolved.

Step 3: Check for Kernel Bugs

If the issue still persists, it's possible that there is a bug in the Linux kernel causing the problem. You can check for any known kernel bugs and see if there are any available fixes. Here's how:

1. Open a web browser and go to the Linux kernel bug tracker website.
2. Search for any known issues related to your laptop model or graphics card.
3. If there are any known issues, check if there are any available fixes or workarounds.
