Understanding the Problem
Before we dive into the solutions, it’s important to understand the problem. The issue arises when the monitor loses signal after the Ubuntu splash screen. This could be due to various reasons such as incorrect display settings, graphics adapter switch, or outdated Ubuntu version.
Solution 1: Check Display Mode or Graphics Adapter
Step 1: Swap Display Cable
The first step is to check if the problem is caused by the display mode or a switch in the graphics adapter. To do this, try swapping your display cable from your graphics card to the motherboard connector, or vice versa. This should be done before booting the system.
Step 2: Reboot System
After swapping the display cable, reboot your system. If the monitor displays the Ubuntu interface correctly, then the problem was with the graphics adapter switch. If not, proceed to the next solution.
Solution 2: Reconfigure GUI Display Settings
If swapping the display cable does not resolve the issue, you may need to reconfigure the GUI display settings. Here’s how you can do it:
Step 1: Access Terminal
CTRL-ALT-F1 to access a terminal prompt. Log in using your credentials.
Step 2: Reset Monitor Settings
Once you’re in the terminal, you can reset the monitor settings to default. Use the following command to do so:
This command removes the
monitors.xml file, which contains the current monitor settings. After this file is removed, Ubuntu will automatically create a new one with default settings upon the next boot.
Step 3: Reboot System
After running the command, reboot your system. If the monitor displays the Ubuntu interface correctly, then the problem was with the GUI display settings. If not, proceed to the next solution.
Solution 3: Upgrade Ubuntu
If the above solutions do not work, it might be beneficial to perform a full installation of a newer version of Ubuntu. This will ensure that you have the latest drivers and settings.
Step 1: Backup Data
Before upgrading, make sure to back up all important data. This is a crucial step as upgrading your system can sometimes lead to data loss.
Step 2: Upgrade Ubuntu
To upgrade Ubuntu, you can use the following command:
sudo apt-get update && sudo apt-get dist-upgrade
This command first updates the package list using
sudo apt-get update and then upgrades all installed packages to their latest versions with
sudo apt-get dist-upgrade.
Step 3: Reboot System
After the upgrade is complete, reboot your system. If the monitor displays the Ubuntu interface correctly, then the problem was with the outdated Ubuntu version.
These are the most common solutions to fix the issue of the monitor losing signal during the Ubuntu booting process. Remember, always back up your data before making any significant changes to your system. If you’re still facing issues, consider seeking help from the Ubuntu community or a professional.
If swapping the display cable does not resolve the issue, you can try reconfiguring the GUI display settings. Access the terminal by pressing
CTRL-ALT-F1, log in, and run the command
rm ~/.config/monitors.xml to reset the monitor settings. Then, reboot your system.
To upgrade Ubuntu, you can use the command
sudo apt-get update && sudo apt-get dist-upgrade. This command updates the package list with
sudo apt-get update and upgrades all installed packages to their latest versions with
sudo apt-get dist-upgrade. Make sure to back up your data before performing the upgrade.
