How to resolve the issue of Ubuntu displaying a black screen and unable to wake up after being suspended?
If you encounter a black screen issue and are unable to wake up your Ubuntu system from suspend mode, you can try the following methods to solve it:
- Press any key on the keyboard or move the mouse to wake up the computer. Sometimes the black screen is caused by the screen saver function, and pressing a key or moving the mouse can wake up the screen.
- Check the power management settings. Adjust the power management settings in Ubuntu’s system settings to ensure the system can properly wake up after being suspended.
- Update the graphics card driver. Sometimes, an outdated graphics card driver may cause the issue of a black screen that cannot be awakened, so updating the graphics card driver could help solve this problem.
- Modify the kernel parameters. Some users have reported that the issue of a black screen not waking up can be resolved by modifying the kernel parameters. You can try adding parameters during startup for testing.
If the above methods are not able to solve the problem, it is recommended to check the system logs for more information and consider seeking help from the Ubuntu community or forums.
